I have a Sears cordless hedger and I just bought 2 new batteries for it. It has been a while since I took the old batteries out so I don't remember how the batteries are wired. There are 2 batteries and 3 wires. 1 red wire, 1 black wire and a green jumper wire. Does anyone know how the wiring should be to connect the 2 batteries together. Any help would be greatly appreciated.
If each battery is approximately 1/2 of the placarded operating voltage then it would be black from one battery to the minus or negative lead of the trimmer, red from that battery to black of the 2nd battery and red from the 2nd battery to the trigger switch. If on the other hand, both batteries are within a volt or two of the operating voltage, then both blacks are tied together with the negative of the trimmer and both reds are tied together and run to the trigger switch. The green wire may or may not be used. If you wish to keep it, connect it to the metal motor housing.
