I originally posted this over at MacNN but this is probably a better place. I have a Pismo with 2 dead batteries. The computer has been tied to my desk now for a year, which is very frustrating. I would really like to get a working battery as cheaply as possible. On google I found these directions on how to disassemble the battery. There are 1 cells, all of them say:
SONY ENERGYTEC STG
So I've been looking around these batteries online. So far I've found these directions on how to do the same for a Sony battery pack. The Pismo pack actually looks easier to do since the soldering looks simpler (although I am not very good with a soldering iron). I've been having trouble actually finding the batteries sold individually. I have seen this company selling them in pairs, in a pre-fabricated casing that I would need to break open. However they're only $13 for a pair, which would give me a new battery for under $60, half the price of replacement Pismo batteries.
So I'm wondering. Hs anybody done this? Is it safe? Will I blow up my PowerBook? Also, Newer Technology now makes these batteries which claim to have higher capacity. Can I just swap out the current cells for higher capacity cells? Does anyone know where I can get these cells cheaply? Thanks.
