Batteries drained...but I have solar!?

Originally posted by sailor323 Upgrading to 2 6v golf cart batteries would give you 225 amp hours (Trojan 105 or equivalent) and 2 Trojan 145 (or equivalent) would give you 265 amp hours.  In addition, you would have true deep cycle batteries that can be discharged more deeply than the marine/hybrids, can be recharged far more many times.  Price for 2 6v T105 not much different than 2 grp 31 and 2 6v 145 definitely worth the difference in price

Those Trojan batteries are not group 24; they are group GC2. Much larger than group 24, or group 31 batteries. Make sure you have room for whatever batteries you choose.

Originally posted by Bhfromme Thanks glue guy. Are Group 27 and Group 31 the same size as the 24 I have now? Not really looking to make major changes. Just want more amp hours.

Nope. They are all a little bit different. Depending on which dimension you are talking about, some can be made to fit into the place of others. Of the ones we are talking about (Length, Width, Height in inches):
