sanyo tool reset bq8030 datasheet catalog

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. bq8030, a lithium battery gauge, to keep track of the amount of charge left in the battery.īy 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 (link). bq29330, a lithium battery protection IC 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: Theoretically Increasing the capacity from 69% of 5.6 Ah = 3.86Ah to 6.8Ah, a 76% increase in battery life!Īfter breaking the casing I saw a really nicely designed and built battery pack. So, I bought some Panasonic NCR18650B Cells (3400mah) for 6 euro a piece (can be bought cheaply here in China, just watch out for fakes) and decided to put them in.
