How to Open a Laptop Battery & Replace the Lithium Ion

Laptop batteries, like all rechargeable battery packs, lose their charging capacity over time. Because new laptop batteries are expensive, replacing the individual cells inside the battery casing can save a lot of money. However, rebuilding a battery sometimes does not work as expected, so it’s important to be willing to purchase a new laptop battery if the procedure fails.

1. Allow the laptop battery to run down completely. Turn off your laptop, then remove the battery. Write down the model number located on your Latitude D800 battery to help identify the type of Li-ion replacement cells you need to purchase.

2. Split open a small section of the Latitude D800 battery pack (at the seam) with a screwdriver or craft knife. Continue to pry the plastic case loose moving around the outer edge until the entire top is free. This may take a bit of force.

3. Note the number of cells inside the case (usually four to eight). Write down the part number and voltage information printed on the Toshiba PA3107U-1BRS cell casings. Draw a diagram showing the arrangement of the cells and how they are connected, or take a few photos to help with reassembly.

4. Purchase the correct number and type replacement batteries from a local or online dealer, based on your battery model and cell specifications. Six Li-ion cells typically cost around $30 to $40.

5. Carefully remove each cell using a craft knife and wire cutters as necessary. Each Toshiba PA2487U battery pack is different, but the cells are usually wrapped in a plastic casing with metal contacts attached to one end. Lay the metal contacts, wires and casing material aside.

6. Use double-sided tape or a solder gun (only if necessary) to attach the metal contacts to the cells and circuit board. When finished, the old cells should be completely stripped (naked) and the new cells should look like the old ones as much as possible.

7. Place the new Discount laptop battery cells inside the case, referring to your diagram or photos if necessary. Glue the battery pack top back on. Charge the new battery for at least 24 hours before using it.

Keep an eye on the new battery while it charges for the first time. If the contacts are not connected properly, the battery could overheat and cause damage to the laptop.

Customer Reviews

1) There is a rediculous amount of internal circuitry built into battery for voltage and current monitoring during the charge / discharge cycle and for thermal protection as well as LED indicators to show battery health as I do on my pa3465u-1brs PA3451U-1BRS. On tear down of the older battery that this new one replaced, I counted 14 large scale surface mount IC’s and many small ones on two circuit boards.

2) The batteries are spot welded to the connection straps which makes for a strong anti shock connection.

3) Trying to repair the old 4 cell battery… I found that, taking time and the cost of one cell into account, it was cheaper to purchase the new 6 cell battery pack than to try and repair the old one.

Cons1)individual Dell D610 battery cells are extremely difficult to find (in the US) and expensive. These are industrial type battery cells.

2) Unless you have a hot air SMT desoldering station there are no serviceable parts in the battery pack. My recomendation is don’t bother taking one apart… it is a waste of time (and could be dangerous also).

ReviewI purchased this 6 cell battery for my fathers Latitude D600. It was shipped very quickly to the house and my father has been very haapy with his notebook since the new battery was installed. After an initial charge I turned on the D600 and let the system settle down ( hard drive and cd stop spinning ). After about a 5 minute wait I checked the battery level monitor and it showed a 14 hour charge remaining, this happened to my pa3465u-1brs PA3451U-1BRS. (keep in mind that this number can change ALOT when you access the hard drive or optical drive). I am pretty happy with the results.

Normal performance is restored. Too bad it has to cost so much to get there. In general, I’ve had good luck with Dell batteries so long as you condition them properly (run them all the way down before charging, etc.) and battery life is greatly improved over the last few years as vgp-bps2c vgp-bps2a, but the technology is still lagging behind the rest of the machine.

Dell should really start a policy of providing a means to return the old battery in the shipping box for the replacement to allow recycling. No telling how many of the old units wind up dumped into the environment simply because it’s such a pain to get them to a place that recycles. Dell offeres recycling on old PC’s, why not batteries too?
