18v Li Ion chargers and going quietly bonkers
My wife has elected to do some trimming of bushes and I have a nice Tektool brand cordless hedge trimmer. So I went and excavated it from the shed, then checked the battery which has those little green lights to show how much charge. Only 2 of the 3 light up so I think righto give it a charge. So far I've spent about 6 hours looking for the charger with nothing in sight - the trimmer has been in the shed unused for the past months of winter.
Now I do recall the charger was a bracket to slide the battery into and a wallwart transformer connected to it with a lead. I doubt if there were any sophisticated electronics as in say a DeWalt charger. The battery has 3 connections marked + - and C.
Dare I use a simple 18v dc power supply to recharge it?? can anyone tell me what the C connection is for? In the DeWalt cells they seem to have a temperature sensing element but this is so simple I doubt it has anything like that. Any advice gratefully received.
