Max Charging Current of typical GC2 battery
Say the GC2 battery bank has been drawn down to 25-50%, what will be the max current they will initially accept? For sure it's greater than the ~24A max my solar charger has reported as that was l...

The standard book answer is: the amp-hr rating divided by 10. I know many people will argue with this.
So, if you have a pair of 232 Ah 6 volt deep cycle wet cell GC batteries in series that would be:
232 / 10 = 23.2 amps initial charge rate @ +- 14.8 volts or higher.
That said, they will accept much more than that if you have a charger that can do it. At higher charge rates the batteries will heat up and generate significant amounts of hydrogen and oxygen gas which is explosive. If you do not provide adequate ventilation to the battery compartment, eventually . . . . boom! Just like the picture Mexicowanderer posted the other day except you can expect sulferic acid to be splattered around the blast area too. If you are in a hurry to charge your batteries take adequate precautions unless you want mud (well in this case sulfuric acid) all over your face.
Corrected math. Thinking at the speed of light and writing at the speed of sound or less!
