Looks like I will be replacing my coach batteries in the near future, they (only have 2) aren't holding a charge very long, this happened a few months ago & I found they were low on water & the cable hookups needed cleaning very bad, I fixed this problem, but now they are not holding the charge again for more than a few weeks & I do have the 12 volt switch in the off position when at home.

What batteries should I be looking to buy, we only use the RV about 6 months of the year & that only for 3 or 4 days at a time.

If your maintenance habits don't improve, get AGMs. No water, no corrosion. Yes, more money, but well worth it.

cheapest you can find and disconnect the negative battery cable when not in use. Ensure you charge them up a few days worth before you disconnect them. They are not going to last 4 or 5 days without charging them. Higher end battery will last a longer but not 4/5 days without a charge if being used.

Solar is the easy way to charge batteries and keep them charged during RV hibernation.

You can get golf cart batteries Inerstate GC-2 (6v) at Costco for under $100 probably the same price at Sams Club. They will need water AT LEAST once a month. Use distilled water only.

What batteries do you have now...

My recommendation is most always the same G-2's or L-16's depending on several things.

WHY
Group 24 MARINE/deep cycle or MARINE/rv.. abot 75 AH each you can use perhaps 25% before damage (Fast aging) Sets in)
Group 27, 29 and 31 just under 100, over 100 and 120-130 respectively.

GC-2 Pairs are DEEP CYCLE Golf Car batteries. you can safely use HALF the power before rapid aging sets in.. and that's 1/2 of 220 Amp hours give or take 10.
The L-16 is nearly tx that (Also used in six volt pairs)

Watts (amp hours time volts) per pound is nearly identical across all lead acid batteries. Flooded wet, Maintenance Free and AGM.


Home is where I park it.
