Napa 24 RVS Batteries?

Group 24 are about 75 amp hour give or take a couple amp hours (C/20 rate)

if your battery tray is DEEP enough a GC-2 pair will fit in the same space as a Group 24 pair, and give you 220-230 amp hours, a bit heavier but you go from 150 amp hours of MARINE/deep cycle to 230 amp hours of TRUE DEEP CYCLE and that is a major bump in power storage.

Just trying to get specs on them, for someone who has a pair, thanks.

Call NAPA and ask weight. 46 lbs is around tops for flooded group 24
rv batteries.

Anyone familiar with these... like their Ah rating and such?

Thanks!

I don't know the specific answer to your question but they should be very similar to something like the Interstate 24s. There's not a big variance in the common RV/Marine 24 series batteries.

Thanks, Ron,

Yes, the batts in question resemble the specs given for interstate SRM-24's

The SRM-24's are rated at 5a for 16.4 hrs, so I'm assuming that means an Ah rating of 82?

AH is supposed to be at the 20 hr rate so if 82AH the rate would be 4.1a. It is true that at 5a it would last less than 20 hrs but Peukert would say how many. Different batteries types have different Peukerts though. ISTR mena has a table for all this.

If I only knew where that was. :S

Not sure, but this might be the table that pianotuna posted in this discussion thread:

Here's the table:

As wa8yxm said, GCs match the footprint of group 24s and give a lot more bang for the buck. Or at least a lot more bang! We replaced 4 Les Schwabe group 24s with 4 242 AH Golfcarts and are extremely happy with the change. It needed a little metal work to get them to fit but worth the effort. It depends of course how much off grid camping you do.

It depends of course how much off grid camping you do. IIRC, the group 24s were listed at 80 AH. so we went from 320 to 484 AH. Of course in reality only half of that should be used.
