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:

Costco: Interstate battery, Item #517990, size GC2, Reserve Capacity, 100RC, $79.99 ea

Sams Club: Emergizer battery, size CG2, 107 RC minutes @ 75 amps, 220AH, $81.83 ea

Dimensions of the batteries is identical, at 7" W x 10 1/4" L x 11" H. I know weight is important, heavier indicating more lead plates, but I had no scale to measure the weight of each. Both have 12 month free replacement. I realize the AH is probably the most important factor here, since price is pretty close to equal, but the Costco battery did not provide that information. Can anyone tell me what the rated AH are for the Costco Interstate battery?

Any other comments about pros and cons of one of these over the other, would be welcome. Thanks in advance for any information!

To choose a real deep cycle battery just take one of the caps off and look for the one with the warped plates. A true deep cycle battery has thicker plates that warp in the drying process during manufacturing. Starting batteries have thinner plates that are straight.
