restoring Li Ion batteries

Recommended Posts

Hiya all,

Has anyone ever tried restoring/rebuild/wake up Li Ion batteries from PowerBooks? I have a few of PowerBook batteries and recently I got one battery brought back from dead and others aren't working at all.


Someone advised to jump start/shock start the batteries with small spike charge to get them woken up.


Well aware - it could be dangerous procedure, he used an old galvanised toolboxn incase it explodes.

Why not just send it to Batteryrefill.com for a refurbishment? 



All indications are that they are defunct.  I tried to place an order a couple of months back and got a bounce that indicated their mailbox was full, as did all my other contact emails.  Calls to their number went to voice mail which was never returned.
