Robomower charger, so I replaced it with two 12v chargers.
The ones I'm using aren't exactly "smart", but they are smarter that
what it came with. They are intended for electric wheelchairs, so built
better than the usual stuff. They charge at 2.75 amps until the voltage
reaches 14.7v, then hold 14.7v until the current falls under 200ma, then
switch to a 13.7v float voltage.
