Have 4 GC2 batteries, 2 in series and all four in parallel for 12v and 460 amp hours.
installed a new 100 amp charger
which I run off a 8000watt genset. Its a 3 stage charger
and when I turn it on it spikes to 14.5v like it should for about 4-5 minutes drawing about 9-10 amps of ac power, then it switches stages, voltage drops to 13.60 and it draws about 2 amps
which I set to 460 amp hours says its about 14.7% charged, at this rate its going to take days of constant running to get it up to 100% does this sound normal, should I have only set monitor
to 230 ah which is the individual rating of ea battery
any help at this point would be greatful
