Default Re: Jig for pre-warming 'shed shoes'

For any one in need of D cell Ni-Cads go along to your local Alarm electrical shop and they usually have plenty of "old" one in plastic sleeves removed from emergency lighting unit, free to take away. These batteries are changed on a regular basis, I think every two or three years ( could be wrong). I have found one cell goes either high resistance or reverse polarity. I slit the plastic sleeve locate the faulty cell using a volt meter and give it a jog back into life. There are several ways of jogging these cell and I'm sure readers have read about them in the passed so won't repeat here. Whilst the battery is never as good as when new there is a lot of life left for future use. One can do almost the same with cordless power tool batteries. Ted
