I've read where the white wire can be used as a trickle charger for a 6v battery. Can it be used in the same way for a 12v rechargable battery? THANK YOU!
And since it's AC, you can do it without too many parts. You can use a half-wave voltage doubler, which has the added benefit of rectification so you'll end up with about 12VDC which is what you want to charge the battery with.You can convert 6V to 12V...would split the already weak power output to less than 1/2 of what it was at 6V :s
