Charging a battery

[J_Walker]

So my friend managed to kill his lead acid motorcycle battery in his kart, I don't have a trickle charger and of course nor does he.

But I do have a lawn mower battery charger..

It has an output of 15VDC 100mA

Has a warning on it saying, to charge only lead acid type rechargeable batteries.

I know the positive, and negative wires. they have be identified.. I was just curious to if this would work or not. I was thinking that an over nighter [8 hours exactly] would give the battery its juice back, any thoughts on this idea?

also, the battery is still good and was holding charge, he just left the parking brake lights on by accident...

So Try it, or don't try it?

Try it. Its a low charge rate, I don't think it will hurt it.

Just and update, the charging worked. fired right up! 14.1 volts not started, 13.2 volts running. 12.9 volts with all lights on. 13.4 volts max RPM no lights

Just to clarify, 12V is a ballpark figure. A car battery will put out up to 16V
