Costco vs Sams Club 6V Golf Cart Batteries
Hi, I'm about to buy two new 6V golf cart batteries for my TT. I am choosing between the Costco and the Sams Club 6V batteries. Here is all the stats provided for each battery where I live: Co...

OK - I have read and reread every post on here - I wanted to help anyone here considering these batteries.
I have the Interstate 6v GC2 - 100RC batteries - I weighed mine at 62.8
I have an outback power inverter, charge controller and flexnet shunt monitor
These batteries have some peculiar specifications and it took me about a week but I believe I have them dialed in enough to share. Here is what I have and the information I have gathered.
You all will love me for this sheet

I had these batteries set at the typical Absorb 14.8 and Float 13.2 and they wouldnt fully charge by any measure.
Here are the specs I found to provide a full charge at the end of the day
Absorb = 15.3
Float = 13.4
Return Amps = 16amps (smarter than a fixed absorb time)
All settings based on 80deg F with temperature compensation
I have 12 of these batteries wired in series/parallel to get 12v
I went to the trouble of checking SG and Voltage after two full cycles (two full days of running with the spec above) and they showed 12.96 with SG of 1.285 across all cells! (after 3 hour rest with no load)
You are reading right - these batteries hold 12.96 volts for a full charge
Also they seem to be 208AH batteries
