Manual charger question
Is broke or do I not know how to use it?
I picked up a Schumacher SE1052 on Craigslist yesterday. On the 10 amp setting, on a mostly full 12 volt gel battery (yes really gel, not AGM) it starts at 14.2 volts, and rises steadily, reaching 15.3v after 5 or 10 minutes, at which point I unplugged it.
On the 2 amp setting, different battery, also 12-volt gel, it starts at 13.38 and rises more slowly. Now, after 10 minutes is about 13.5.
I'm used to smart chargers. Is this how manual chargers work, or is it defective?
Thanks!
