yes they are actually 130Ah's at the 20 hour rate. The only other group 31 I know of that does that is the Trojan SCS-225 but it is a lot more expensive. The $123.00 is a decent price for the US DCXC 31..US Battery has 130 AH group 31's. Are they actually 130 AH's? I know you liked their batteries. They're 123.63 locally.

Maine Sail,If you're looking at the flooded deep cycle marine batts the group 24, 27 & 31 are the same exact specs as the WM batteries. Sam's, like NAPA just decided to not include the 20 hour Ah rate on the batteries.
12V Flooded
Duracell Group 24 Deep Cycle = 75 Ah
Duracell Group 27 Deep Cycle = 90 Ah
Duracell Group 31 Deep Cycle = 105 Ah
6V Flooded
Duracell GC2 6V = 215 Ah
Duracell EGC2 6V = 230 Ah
I have these batteries as well. How did you read the date code? Did you use the round sticker with a single letter and digit (mine said F2 for June 2012) as the manufacturing date or something else?Duracell battery problems?
They had a manufacturing date code of Feb 2012, so were very fresh.
Rodd,Duracell battery problems?
I purchased the EGC2 Duracells in April 2012 at Sam's Club. They had a manufacturing date code of Feb 2012, so were very fresh. I installed them in May and first used them away from the dock this past week. They were very disappointing. They had been stored at dockside on a charger at 13.2 v float. On my cruise after only a couple of hours where the only load was a 12v reefer system drawing max 5 amp. The voltage I read was 12.1 and later on 11.8. This after only a few hours of draw.
I plan to exchange these for two others, but I wondered if anyone else had any issues with these batteries?? Hopefully this was just a rare case.

I called Johnson Controls who make the Sam's Club Duracelldid you happen to ask them about the optimal charging rate for them?
The Sam's Club Duracell batteries are made by Deka/East Penn. The Energizer brand they used to sell were made by Johnson Controls.I called Johnson Controls who make the Sam's Club Duracell
Model: Group Size EGC2
Item #: 347631
They said 14.4 volts is right for charging
We used to have the Energizer/JCI batteries but I am darn happy we now have the Deka/East Penn batteries.... Not all clubs have the Duracell/Deka/East Penn product and some apparently still have the Energizer/JCI product.. Could be regional?Interesting, Maine.. I think that the Deka's are only available in a small market.. My local club handles the Energizer labeled battery and the ad is accompanied by this:
ONLY AVAILABLE IN AK, AR, AZ, CA, CO, HI, IA, ID, KS, LA, MN, MO, MT, ND, NE, NM, NV, OK, SD, TX, UT, WA, WI, and WY..
Looks like you guys aren't in the list for the Energizers.. Still has pretty good specifications;
