charging batteries
Am installing two six volt batteries, each has a 200 AH capacity. Will be recharging them with genny and/or shore power until we get our solar setup installed. If the batteries are at 50% capacity h...

Generally speaking applying a set 14.8 volts (the instant you start the charger voltage jumps to 14
8 and stays there, allows the batteries to fill above 90% full in three to four and a half hours.
The downside is the initial charge rate has to be above 200-amps to do it this quickly. Higher capacity GC-220 batteries would demand >250 amperes. Toward the end of charge total amps would be in the forties.
My goodness, Mex, that's getting serious! We regular humans using about 25% charging rates get it done as posted in the ugly graph above, but the 90% marker then becomes when amps have tapered to about 5 amps per battery at 14.5v (so 10a with two batts or 20 amps with four)
