Notebook battery review

The Digital camera battery daily maintenance

At present, there are two types of digital camera batteries, professional lithium batteries and 5 AA batteries. The professional lithium battery is very light, high capacity, environmental protection, and no memory effect, but the price is expensive, and can’t be use generally. Ni-Mh battery with high capacity, and discharge deeply, and durable to charge and discharge, short charge time and other obvious advantage. The most important of all is cheap and can be use generally.

No matter what kind of Sony NP-BG1 battery, as long as it company sale with digital camera, the user manual will indicate the attention items, some manufacturers even print out a single user guide of Canon BP-511 battery, and charger. Those manual are the basic but useful maintain instruction, such as the charge method, charge time of the battery. It is necessary for the new users to take few times to read it.

Normal users don’t have a professional bag to store the Kodak KLIC-5001 battery when use the digital camera, they usually put the battery randomly no matter the place is clean or wet after replace the battery. It is easy to dirty the battery, and contact with metal things, such as key, it also maybe wet, those are the enemy of battery.

Suggestion: User should find a professional position for the Casio NP-30 battery, and keep its clean. In order to avoid the power losing or any other problem, keep clean of battery two side touch point and battery cover, you can clean it with soft dry cloth when necessary.

If long time no need to use the digital camera, then you must take out the Fujifilm NP-40 battery from the camera and store it in dry and cool environment. Regarding the Ni-Mh battery, it should be discharged fully then store it or store it with power? The two different point, should adopt which one? A lot of people choose the former, but I think it is more reasonable to store the battery with power. Because according to the test, the best condition of storing a Ni-Mh Olympus Li-12b battery is with 80% power. This is due to the Ni-Mh battery discharge itself at 10-15% monthly. As you can as well, the new Ni-Mh battery always have power, it is the same reason.

Make your laptop battery last longer in some daily habits

1. Use the lowest brightness settings on screen displays.

This will not work in bright areas like out doors, but sure works well indoors. Cell phones, lap-tops, and even watches have brightness controls that will help stretch the life of any laptop battery.

2. Fully charge and discharge all of your batteries.

Try to avoid “topping off” the battery if there’s enough of a charge in there to get by, then remove the battery or unplug from the charger only after it has had a chance to trickle charge at 100%, and your Sony NP-BG1, Canon BP-511, Kodak KLIC-5001 battery will last 2 or 3 years easily.

3. Use programs that take less RAM and keep useless programs closed.

A lot of laptops come with cluttered programs since the day you take them home from the store. Stuff like Yahoo messenger or Firefox with 20 tabs open takes a lot of RAM and eats up batteries super fast.

4. Keeping the volume level on all of your music playing devices is key to a longer Latitude D620 battery life.

You’ll be amazed at how much life loud music sucks out of your battery. This will also do wonders in preserving your ear-drums as well.

5. To go with #4, also turn down the volume on your cell-phone ringer.

Long ring-tones may sound cool, but hearing your favorite song play every time your phone rings will drain your Dell inspiron 6400 battery in a hurry.

6. Turn off your Bluetooth whenever you’re not using it.

This can be an easy one to forget about if you’re often switching between using a Bluetooth, and the phone’s ear piece. Most people use their Bluetooth way too much anyhow, so cutting back on it’s use will lengthen the life of your Dell Inspiron B130 battery.

7. I’ve always heard that when you get a new laptop, or anything with a rechargeable battery for that matter, you should charge it over night.

Pull that bad boy out of the box and give it a nice, long, healthy charge. Even if it says full, leave it in and charging for a while.

8. When I was little I would always find VGP-BPS2C VGP-BPS2 batteries in my grandmother’s fridge.

I always wondered why, turns out she was onto something. If you have extra batteries for your phone, laptop, or anything else, go ahead and store those in the refrigerator. Just make sure not to freeze 40Y7001 40Y7003.

9. Programs that are run from a CD or DVD can be copied to and run from the hard drive, which typically consumes less power than an optical drive.

If you have music and movies you know know you’ll be playing numerous times, just rip them onto your hard drive and you’ll be styled!

10. Lastly, just using basic common sense will help extend the life of all of your Dell KD476 Dell Inspiron e1505 Battery.

If you’re not using it, turn it off! If you don’t need it, get rid of it! This is probably the most practical and applicable way to get the most out of all of your batteries.

Why laptop battery explode?

Laptop battery is composing of enclosure, interface, cell and control circuit board, battery cell is responsible for supplying and storing the power of the laptop. Control circuit board with complex working principle and design, it controls the battery start and stop charging at proper time, control the discharge current reasonable, and it also take charge of showing the battery capacity and recycle charge times recording. When the battery in a high temperature or large current and other un-normal condition, it the control circuit board can protect the battery.

The OEM post in http://www.laptops-battery.co.uk/

The four suspicion of laptop battery explosion.

A, Battery cells interior short-circuit

The Latitude D620 battery cells has no protection function when meet large current, if single or multiple cells happen short-circuit situation, it will let cells discharge at high current. These current generate large quantity of heats will let the battery enhance the temperature, and then transfer to the other parts of laptop.

If the Latitude D600 battery enclosure is plastic material, it will deform or even get fired under high temperature, it is dangerous. The regular cells has experience strict test when out from factory, and the battery enclosure always adopt fireproof material and difficult to get fire. So the most possibility is involved with poor quality material for VGP-BPS2C VGP-BPS2 VGP-BPS5.

B, Battery cells connector wire short-circuit

The Dell Inspiron 6000 Battery, interior structure is too compact which leave opportunity for the cells. The wires in the middle are quite compact and close to the cells, if the skin of the cells and wires wore out, or the connect wires break off, then the cells will discharge at very high current and bring high temperature and cause fire final.

C, The control circuit invalidation

Sometimes, the control circuit will be invalidate for its protection part even it performed normal when use Sony NP-BG1, Canon BP-511,, when under full charge and un-normal, large current situation, the temperature will enhance and cause fire.

D Heat and abrupt incident

The laptop over heat or exterior liquid corrode, lightning strike or voltage un-normal will cause short-circuit.

Electric vehicle battery trouble

At present, Many customers like to buy electric vehicles as their advantages such as light and non-polluting . Mileage measuring of electric vehicles is one main criteria of quality, while the laptop battery is the decisive factors of mileage of the length. In the quality of the many complaints of electric vehicles, more than 95% of the problem is about laptop batteries, what is the wrong of problem?

“Battery Rehabilitation centers” professionals point out that where the problem lies : factory competitive price , reduce the battery cost.

Electric vehicle manufacturers generally use the Dell inspiron 6400 battery that provided by professionals battery manufacturers. Different brands and different manufacturers vary the battery quality. Some manufacturers to participate in market competition and reduce the costs of battery, which is a direct consequence of causing the battery due to jerry-built quality.

Low After-sales service

In accordance with the relevant provisions,Dell Inspiron 6000 Battery electric vehicles as the main components, a corresponding quality of the guarantee period. The failure of the battery during the warranty period, producers should assume responsibility. In real life, some merchants or manufacturers have neither the expertise battery maintenance, the warranty period of batteries do not seriously addressed, consumers are asked to pay only for the battery.

Consumers do not know the proper use of batteries

Some consumers improper use of Ibook G4 12 battery . One is the longer charging time the more adequate electricity; second a long time electricity loss, only charge the battery until exhaust; Third, the temperature too high or too low when charging; Fourth, pay no attention to the battery regular inspection and maintenance.

How to properly charge and discharge

The right to use a certain extent, can play the role of extended battery life. Are on the correct use to be a brief introduction:

Should not have been riding on the charge

Battery life is a decision to charge and discharge cycles. Therefore, do not charge the Ibook G4 14 battery when used, it should be charge the battery at 60% -70% exercise of mileage .

Second, the charging time should not be too long

Many electric vehicles users think that the longer charging time can fully charge the VGP-BPS3 battery . This is very wrong. Charging time generally extended one hour after the lights change. Over a long period of battery charge easily lead to deformation, water loss and so on. Directly reduce the Pavilion ZD7000 battery life.

Third, it is best to use Smart Socket

Many electric vehicle users charge the battery when back home and cut off power when go to work the next day , in fact, most of the charger can not guarantee 100% automatically when the battery is fully charged. The best way is to buy smart sockets, Set the charging time for Sony NP-BG1, Canon BP-511, Kodak KLIC-5001 .

Dont use the electinic vehicles when power loss

Some users only charging the battery when power exhaust, it can damage the battery performance deeply.

Fifth, do not charge the battery when temperature too high or too low.

The process of charging, the battery itself will have a small amount of heat, high temperatures in the charging will increases bottle body temperature, that damage to the battery performance. Temperature is too low. Battery active is not enough, lack of battery power, increase the charge-discharge cycles and shorten Pavilion dv4000 battery life.

Lenovo recall battery again

Laptop battery have problems again? Lenovo today announced the recall all battery,

Lenovo Group, the official website linked to the issue of a replacement lenovo battery free of charge information. Although the relevant responsible person stressed that the issue of batteries does not pose a security risk, and intention to play down the incident, but still caused concern to the industry.

ThinkPad users as a result of a small number of reports, there can not charge laptop battery or low battery capacity, such as short battery life or a sudden drop in power the question of scale. Legend explains that "the battery can not repair the damage" or "battery can not charge" the emergence of information means that the battery can not discharge or charge. This is a permanent battery failure, but does not constitute a security risk. And low battery power, it means that time is short battery life, a sudden drop in the power scale.

If battery failure due to this problem, Lenovo will be a free replacement battery. "The official line of Lenovo Group, Lenovo areas indicate the scope of the replacement of batteries, announced the recall ThinkPad R60 battery, R61, T60 battery, T61 battery, X60 battery, X61 laptop battery part number. Lenovo said that all official information to explain the replacement of the main , is not to say that the above-mentioned 10 models of all models have the issue of batteries. users through the installation of diagnostic tools to check the battery, it still can not predict the number of batteries need to be replaced. windows users can use this tool to detect, to to determine whether battery failure due to this problem and to comply with the conditions of a free replacement.

In fact, this is not the first time the issue of Lenovo laptop battery action. The earlier outbreak of Sony "battery door" incident, Lenovo and Hewlett-Packard, Dell and other PC issues are also trapped in the work to improve the battery recall.

Asus Eee PC is becoming the history, Netbooks is stepping into declining years

The article is first posted in http://www.laptops-battery.co.uk/blog/

Along with the Intel readjustment, after Netbook experienced a prosperous age, it become step into the old age. Asus and Acer are the first to announce stop developing & researching netbooks to follow the light & thin laptop battery comprehensively.?

According to relative media reported the two laptops manufacturers, Asus and Acer has already stop the develop working of this second half year but turn all the energy into the light & thin notebooks like Latitude D600 battery. This is mainly because Intel postponed the publication of next generation netbook flat roof Pine Trail-M and MID flat roof Pine Trail-D to the 1st quarter of 2010.

But there is some information disclosed that ASUS may promote Android flat roof netbook products the later of this year, but the publication date is after October. Besides, touch model flat netbook Eee PC T91/T101 products will be follow up after the official selling of Windows 7 with dell laptop battery.

Another side, for the light & thin laptops based on CULV flat roof, ASUS already prepared 12 inch, 13.3 inch, and 15 inch machine type, 13.3 inch is the mainstream products, and it will be increased 12 inch and 14 inch model in August as Ibook G4 battery.

For Acer, the netbook products are still promote 10 inch Acer Aspire One battery series as the main products. Regarding the light & thin laptops, Acer already own 13.3 inch, 14.1 inch, and 15.6 inch, three machine models, and plan to add the model with collocation of ROM and independent display card according to the needs of market.

The two leading manufactures stop developing netbook products to developing thin and small laptop (Powerbook G4 battery), it is not some goods news for netbook market and it will bring chain-reacting. Meanwhile, it also proved that netbook market has already passed and will be replaced by light & thin laptops.

The answer for laptop battery frequent asked questions

Last week I buy a Dell notebook from Dell.com, then I want to know some laptop battery tips and problems by google. I found many frequent asked questions about laptop battery, but there are various answers for them. So I send a email to laptop battery expect “Jack Smith” in http://www.laptops-battery.co.uk/ about these doubts. He reply me in the August 11, below is the reply content.

What is the six months warranty laptop battery?

Generally the laptop battery quality warranty is one year, but we can find many 6 months warranty “Original laptop battery” in ebay and other online shops? What is these six months warranty laptop battery?

Most the six months warranty batteries are the old battery with the new cells, old original battery shell and protection board. You can find the detail introduce here “How to replace battery cells inside laptop battery“. As the battery protection board is old one, so the laptop battery can only work properly about six months.

For laptop battery, the higher capacity the better?

For different models (particularly different size) battery, the higher capacity battery can work longer. Exclude the size and weight factors, of course that the higher capacity the better.

However, the same battery type, the same nominal capacity (for example,Inspiron 6400 battery 6600mAh), the actual measurement capacity is different: for example One Inspiron E1505 battery capacity is 6600mAh, and the other is 6700mAh, then the 6700mAh battery is better then 6600mAh?

The actual situation may be that : In the high capacity battery’s electrode materials, increase the initial capacity of more things, and reduce the materials to stability of the electrode. It may result that after used for some charging-discharging cycles, the capacity of high-capacity battery reduce rapidly, while the capacity of low battery is still strong. Many laptop battery manufacturers often use such method to produce the high-capacity battery. After used for six months the GD761, KD476, TD347 battery standby time is too less.

Enhance the battery capacity can reduce the battery cycle life. If the laptop battery manufacturers are not make great efforts in battery material, it is impossible to truly “improve” the capacity of the battery.

It is worth to store the fully-charged battery

Lithium-ion batteries have a very bad characteristic, that is the lithium-ion laptop battery aging time. When a lithium-ion battery in storage for some time, even not in recycled, its capacity also lost in the storage. Because the lithium-ion battery anode materials begun the failure process when manufactured. Different temperatures and Pavilion DV8000 batteryy charged state cause the different consequences statute. You can the get the general conclusion by following data ( the percentage of capacity in the form):

Storage temperature - 40% state of charge ——- 100% state of charge

0 degrees ———- 98% (a year later ) ——- 94% (a year later)

That is the all, hopes that can help you.

 Notebook Power Consumption on Test

So far, I’m very anxious to see how much power I can save with my laptop (let’s say - if I turn of my screen, my speaker, my ODD, etc). Well, this time I have chance to test myself

I use my laptop, ASUS F3JC. Powered with Intel T7400 (2.16 GHz), 2 GB or RAM, 120GB of SATA HDD, 15.4″ screen, and a Super Multi ODD. What else? I use standard 65 Watt  EVO N610C battery adapter.

I use a device that can measure the power consumption directly. You just need to plug this device on to the wall outlet, then connect your peripheral to this device. Then, Pavilion DV8000 battery device can measure the power consumption of your peripheral instantly (real time). Take a look of the device below.

This tiny little device can measure the Voltage, Current, Power Consumption (in Watt or VA), Frequency (Hz), Efficiency (Power Factor), and Power Usage (kWh). This is a great device, but somewhere not available in Indonesia to 6y270, pa3395u 1brs, 40y7003.

And here is the result:

With minimum brightness (one step before completely off), I get 21 Watt of power consumption (with processor clocked at 994 MHz). Additional 2 Watt is needed if I set my processor at 2160 MHz. With full load (2 core all at 100%), my notebook will consume around 28 Watt (at 994 MHz) Inspiron 1520 battery and 56 Watt (at 2160 MHz).

With medium brightness (half step between completely off and maximum setting), I get 23 Watt inspiron b130 battery of power consumption (with processor clocked at 994 MHz). Similar with the result before, additional 2 Watt is needed if I set my processor at 2160 MHz. With full load (2 core all at 100%), my notebook will consume around 30 Watt (at 994 MHz) and 58 Watt (at 2160 MHz).

With maximum brightness (maximum brightness setting available), I get 26 Watt  Laptop battery of power consumption (with processor clocked at 994 MHz). A little bit higher, I need additional 3 Watt if I set my processor at 2160 MHz. With full load (2 core all at 100%), my notebook will consume around 34 Watt (at 994 MHz) and 61 Watt (at 2160 MHz). I also test with single core only (100% load on first core, and idle on second core). The result has no different in significant margin I think. I will use around 33 Watt vs 34 Watt in 994 MHz and 54 Watt inspiron 1526 battery vs 61 Watt in 2160 MHz. I think this is because the second core is not totally shut-off physically, only not used at its maximum load.

Additional test:

• Speaker at maximum volume will consume around 1 Watt
• WLAN will consume around 1 Watt
• Spin-up CD/DVD will consume around 3 Watt
• Reading CD/DVD will consume around 6 Watt

Conclusion:
Well, from this short article, you can see that actually, the back light of the screen will not consume too many power as we have thought before (please remember that I’m currently using Thinkpad t20 battery, Thinkpad T42 battery 15.4″ screen, it will consume less power for smaller screen).

If we can do some math, with minimum back light (full processing power) will consume around 56 Watt EVO N600C battery, while it will consume around 61 Watt with full brightness. The 5 Watt different means around 10% only. So if your battery should last 4 hours, with maximum brightness, it will last around 3,6 hours (or around 3,8 hours with medium brightness). A price that you have to pay for a comfortable screen?

WLAN and speaker will not consume a lot of power, but reading (or writing CD/DVD) simply will. Even the spin-up process (after you insert a CD/DVD in to the drive), will consume around 3 Watt of power.

How to measure the power consumption of notebook battery

The Original article posted in http://www.laptops-battery.co.uk/blog/

Why laptop battery capacity reduce as time? Why battery calibration can improv battery capacity? How to charge the battery correctly? All above probelm are related to battery power consumption. Open circuit voltage measurement … … Coulomb measurement, impedance measurement, what are these terms mean? Here we will simply introduce all of them!

Whether it is the out nickel-metal hydride batteries, lithium-ion Dell laptop battery, or not commonly used lithium polymer batteries, and even coming silver zinc batteries, are equivalent to the a storage warehouse of electronic power. The differences between them is that the way out of the Treasury, the volume of stocks it. In laptop batteries, there is a power manage center - power consumption chip, it is the management of power measuring, charging and discharging managing.

In the measurement of battery technology, there are four kinds common method (open-circuit voltage measurement, Coulomb calculation, impedance measurement, integrated look-up table method), but not all IBM laptop battery used only one method, usually using a combination of methods to one of the main method of supporting the rest of the way computing power. The first one is the open circuit voltage measurement, this method is that measuring the battery voltage under static values to calculate the remaining battery capacity, but as a result of stationary lithium-ion battery voltage and remaining capacity relation is non-linear, so this method measured valueis not accurate, the vast majority of mobile phone batteries are calculated using this method;

The second one is Coulomb calculation, the method is by measuring the laptop battery charge and discharge current, the current value and time value After the calculation of product integration has been carried out by filling the battery into the power and the release of electricity, Coulomb’s method is a accurate method of calculating power;

The third one is the impedance measurement, measuring its resistance to get the remaining battery capacity value; the fourth is a comprehensive look-up table method, by setting up a related form, the voltage, current, temperature and other parameters, you can query the remaining battery capacity.

Therefore, in addition to the internal structure of the battery batteries, there are control chips, the chip which contains 1-2 kinds of batteries power measurement method of calculation, and a charge-discharge protection circuit. HP laptop battery manage program had been setted in the system, and through access to the chip-driven interface, and then set on the battery management.

So, why the Toshiba laptop battery will become weak, but the battery calibration can improve the battery capacity? Notebook battery 6-cell and 4-cell, means that there are a number of battery cells inside the battery. The batteries cells conenect together, the battery capacity reduce reason is that: all the batteries quality and discharge rate can not be in the same level. After discharge, one battery cell capacity in substantial reduction, in order to maintain voltage stability, the battery management chip will be according protection of core power as the “bucket principle”, so after the electricity charge will decrease.

Battery calibration is to balance the multiple batteries cells, the Apple laptop battery cells own internal resistance can not be completely consistent, the large internal resistance battery will shoulder the larger current, and its own consumption more than the other batteries. So regular battery calibration is necessary - it can balance the burden of multiple batteries work and prolong the whole battery life.
