me sorry about the original question. Im probably the one that got it all started. It is all sorta related haha... I learn more and more about the batteries every day. Right i am learning all you have to do is weigh one and you got all the specs right away. I think that is what SMKETNER told me a year ago...
My Posts are IMHO based on my experiences - PM me Roy and Carolyn

I just happened to look at the COSTCO golf cart batteries a few hours ago but didn't take a picture. They were priced at $79.99 here. Seems that some items you see at COSTCO and SAMS are priced, based on how close the nearest competitor is located. I have seen people taking notes walking through COSTCO and I asked if they work for SAMS. The answers are always yes. They're easy to pick out. I'm sure the opposite is true also.

Hopefully your charger is a smart-mode charger. Use the 40AMP mode.If it is a smart mode charger it will apply 14.4VDC across your 12VDC connection and will charge at that DC voltage level for about two hours. Then it will step back to 13.6VDC and continue charging for an additional hour. It should return the two 6V batteries connected in series to 90% charge state in 2-3 hours. If you leave it charging it will reach 100% charge state in ten hours or so.
Consider this comments from Progressive Dynamics on charging a deep cycle battery.
Progressive Dynamics ran this test on the amount of time it took a PD9155 (55-amp) converter/charger set to three different output voltages to recharge a 125 AH (Amp Hour) battery after it was fully discharged to 10.5-volts.
14.4-VOLTS (Boost Mode) – Returned the battery to 90% of full charge in approximately 3-hours. The battery reached full charge in approximately 11 hours.
13.6-VOLTS (Normal Mode) – Required 40-hours to return the battery to 90% of full charge and 78-hours to reach full charge.
13.2-VOLTS (Storage Mode) – Required 60-hours to return the battery to 90% of full charge and 100-hours to reach full charge."
If your battery charger only puts out 13.6VDC then it will take 40 hours to reach 90% charge state and 78 hours to reach a full 100% charge (this is a long time especially if you are camping off the power grid for a three day weekend).
The best deal is to have a smart-mode converter/charger on your RV trailer and plug it into a shore power connection or 2KW Honda generator setup and let the on-board converter charge your batteries. If you dont have a smart mode converter/charger get one and it should be at least a 45AMP model for two batteries like your two 6V GC2 batteries.
After you have now connected these two GC2 6V batteries in series just consider them as ONE 12VDC battery from now on. There is never any need to disconnect the battery cable jumper running between the two 6V batteries that made it a 12VDC battery. You probably cant find a 6V battery charger anyway. DO NOT charge one of those 6V GC2 batteries with any DC voltage over 7.5VDC. This may destroy your brand new battery if you put 14.4VDC on the 6VDC battery for any length of time. Always leave the two GC2 batteries connected together in SERIES and charge them both at the same time with the 14.4VDC, 13.6VDC, and 13.2VDC that comes from your converter/charger setup or a portable external charger like the B&D VEC1093DBD 40AMP smart mode charger.
