old batteries

[Mr Ed]

Hi,

Has anyone got any ideas on how to fix old batteries ?. I hear you say buy new ones but
Some chap on ebay is selling some info on repairing them.

Cheers Ed

There is places you can leave them in and they will try and breath new life into them

Sssshh.
Anything can be repaired. If you have the time and more money than it would cost to replace.

I've seen some demos on youtube where they just replace the cells.

If only it was that simple.

 

[telectrix]

what you do ( and this is only for ni-cads. won't work on N-Mh or Li-ion ) is open the battery pack up, then apply 12V from a car battery to each cell for 2 seconds reverse polarity. i.e + to -. then recharge.

Or drag a load through them while charging.

Those prices are crazy, I just got some replica makita battery's from Axminster that come with a 5 year guarantee which were cheaper than those prices
