rebulding few batteries
hi guys,
i'm planning to open up and rebuild few vintage laptop batteries. wondering if it's guaranteed that I'll end up with some sort of visual damage on the casing regardless of how gentle i pry open the casing? on the videos i have seen people shove a screwdriver in between shells and yank it open which obviously would leave permanent marks on the opening spot.
also would you recommend a particular website/vendor/brand where i can buy the cells please?
cheers

Re: rebulding few batteries
99% percent of batteries were designed to not leak/explode at all costs. So....your choice is basically to pry open a glued/sonic welded explosion proof case. Your not getting it open with out damage(unless your talking the battery for the Zenith Supersport or FMA3300 series machines, in which case you can just unscrew them open). Which specific machines are you trying to open? With the T4x, peel from the back, it will separate from there. Work your way around and check which side snaps into which side. I got one or two of those open with very little damage. Also for the A3x batteries, push downwards I believe. Make sure to find which side snaps into which, and push the screwdriver/knife in and down to that side. Also can get those open without much damage if you work carefully.

Re: rebulding few batteries
tried to buy some test vintage batteries from ebay to practice on them. however they were all confiscated and disposed off by New Zealand post before even reaching NZ, i didn't know back then but they are considered fire hazard. not sure if same restrictions applied to other countries too but you can't just import laptop batteries into NZ by themselves using normal post, you can if they are inside a laptop!!!

Re: rebulding few batteries
Should all be similar construction. The 755CE/CX batteries were a total pain. Be careful and you should be fine.
