Solid state battery charger full#
As the battery gets more charged, it will draw more current, and then as the battery is getting full it will draw less current again. When you first connect the charger, if the battery is really dead, it wont draw much current (look at the ammeter on the front panel). I don't know where you would get a manual, but there isn't much to it. I don't think anyone still makes these chargers. If you connect it to a dead battery it charges it, unlike many modern "smart" chargers that will refuse to charge a battery that is dead (yes, that is really true).
There were a bunch of brands, all electrically alike except for the appearance, and even the appearance didn't vary much. There is most likely a transformer, 2 diodes (probably copper oxide, riveted to the case), an ammeter, and a switch.
Solid state battery charger manual#
It is a manual charger, with not much inside. This is what, in the old days, we called a "battery charger"įrank DuVal nailed it.
