[dsn_klr650] impromptu battery charger
Posted: Wed Apr 19, 2000 11:59 pm
Often the open circuit voltage of a 12v little black box is 13-15v or maybe even higher. But at a load of 600ma it should pull down to 12v. I'd hook it up to the battery and after a day or two, measure the voltage at the battery, with the black box attached and charging. If it's any bit over 12v even 12.5v I'd say you have a free trickle charger.
