Then desoldered the wires running to the old battery pack and done! After sliding the battery back into the laptop and trying to switch the laptop on. Added some new double sided tape to the old plastic casing and put the batteries in: I Soldered the tabs to the PCB again, taking good care not to short circuit anything. The plastic seperators from the old pack were also reused.

It takes a bit of force, but you can get the tabs off in reasonably good shape.ДЄnd I attached them to the new batteries by soldering them together with a really thin layer of solder. Then I slowly started to dismantle the old battery pack for the solder tabs connected to the pcb. So I soldered wires between the testpads and the tabs on the old batteries. Luckily Lenovo provided some testpads right next to the places where the batteries are connected to the PCB. To keep the protection circuit from detecting the change in batteries I would need to keep the pcb powered with the old batteries until the new batteries were connected. After waiting for a night the cells from the old and new pack had the same voltage. Back home, I first made sure both batteries had about the same voltage, the bad banana plug wires I used had enough resistance to keep the balancing current under 1A.

You cannot just solder wires to lithium-ion cells, they will just overheat and might even explode! Luckily at the moment I am living in Shanghai, so I went to a small electronics factory and spot welded some connections to the batteries (I did it myself) and connected them together in a 3x2 batteries in series way. Thanks allaboutcircuits, for not letting me end up with a busted battery pack! Not knowing when the fuse would be blown, I had to proceed with caution. This is quite understandable, just another safety feature Lenovo build into the lithium battery I guess. So checking the PCB again I found a curious small circuit which burns a non resettable fuse when problems are detected, trashing the battery. Being curious about the IC's on the PCB I searched online and found two trustworthy IC's from Texas Instruments doing all the hard work: - bq29330, a lithium battery protection IC - bq8030, a lithium battery gauge, to keep track of the amount of charge left in the battery.Д«y chance I also found a site where they tried to refurbish a battery pack from a Lenovo battery pack and it did not work because of safety features on the PCB (). After breaking the casing I saw a really nicely designed and built battery pack.
