Nicad Batteries Back to Life

[Fred Hulse]



Thanks to Curt, Itried the method of renewing a couple of well used Batteries for a very old 12 voltCraftsman drill I have.

Battery # 1

This batterywould not charge at all when putin the charger, the best I could do was watch the red lamp on the charger flash,indicating a bad battery. After the procedure in the guys video I got the same results, but finally figured out what he was trying to do.I believe my battery was so discharged it may have reversed the polarity, I am only guessing of course,considering I don't have any sage knowledge about these things. I decided to charge it a little bit with theautomotive battery charger and it tested11. somethingvolts,then I placed it in theSears charger and the red light was solid indicating it was charging normally,after about three or four hours the lamp had turned green indicating it was slow charging and had reached its 12 something volts.The battery has tested 12 plus volts and has never worked that ole drill better!! Very pleased with the outcome.

Battery # 2

This is aChinese replacement battery I bought online from a vendor selling Heavy Duty Replacements for your Craftsman Industrial drill,I have been able to use it about 10 minutes at the longest since I started using it and it would then be a dead Heavy Duty Replacement.Using the same method it appears I have revived it to live up to its name and will spin the ole drill much much better. I would not be surprised if it loses its glamour. Not very pleased with this one.
