It`s winter time and cold and as usual the tractor battery is almost
dead. The regular charger and the trickle charger boils
out the water. A neighbor says he uses a " float charger". Can someone
tell me what a float charger is amd what does it do?
Thanks a lot

It's a smarter charger which brings a 12V battery up to full charge,
which is around 14 volts, then backs off to a low current and monitors
it to keep it at around 13 volts, which keeps it charged without over
charging it.
