I have the out of production SC2500a that does a 2/12/25 amp recharge rate.
It will do voltages upto 16 volts, when it decides to do so, and for this reason should likely not be used to charge a battery which is still connected to the vehicle.
I hear other Schumacher chargers will do the same thing.
One weird thing about my Schumacher is the 12 awg cables going to the alligator clamps are junk. The copper inside the wiring is black, it heats up greatly at 25 amps, and removing most of this junk wire has allowed this charger to perform better in my system.
I do like the high voltage capability. I do not like that I cannot choose when it does this. It will go right past 14.8v at 12+ amps and climb upto 15.8v and really just blast the battery with 10 to 12 amps at this point.
I don't mind the 15.8v. I'll program my solar on occasion for 16v, after a "full" charge and it will take 6 amps to get there. i don't like how the schumacher just rockets past 14.8 and takes it upto 15.8v feeding 10 to 15 amps. It seems like a violent way to charge a battery and perhaps why this particular charger was taken off the market after a short time.
