Batteries: Marine/RV or Marine?

OK folks, getting time to get another battery to replace my nearly four year old Interstate group 24. Got it at Sams and it has been a good one. But Sams does not sell Interstate any more. But they do sell Energizer which is distributed by Johnson Control. But it is time for a new one to be safe.

Should I get a Marine/RV or a Marine battery? I know we need a good battery for trailer brakes, slides, furnace, lights and other goodies.

Not sure I know the difference between Marine/RV, Marine Battery or Deep cycle. Been reading up on batteries, but it has become confusing to this old Boomer! Thanks in advance

Marine/RV or Marine Battery are the same animal........unless it is a marine starting battery. Marine/RV are deep cycle batteries but are still something of a compromise between a starting battery and a deep cycle. When you're looking for a replacement, compare the amp hour ratings of the batteries you are considering. The Marine/RV battery will also have a cold cranking amp rating (cca) but that is irrelevant to your use of the battery; amp hours is what matters for use as a "house" battery.

I have two group 27 Interstate Marine/RV batteries on our WhiteHawk. Did a 3 day weekend dry camping with them a couple months back and they were still about 60% capacity when I brought them home and put them on the charger.
