switching to two 6 volt batteries?

10min to add water a couple times per year...ehhh. Should be checking on connections etc anyway.
Never spilled acid or had fumes do any damage, so...ehhh.

Fumes will corrode things when the batteries gas when charging.

It's more like 30+ minutes to check batter fluid level in an AF camper.
You can't get access to the inner battery, even though they are on a useless sliding tray that most AF owners despise.
The tray only slides half way out.

The only time I was able to check the water was when I took the camper off the truck for the winter and was able to disconnect the batteries and removed them to check fluid.

Checking water when the camper was on the truck was an impossible feat because getting them out required the use of a ladder. Carrying them down a ladder isn't fun (or safe)

I had the same tight battery box… My solution for watering the two GC’s was to remove the tray and add an automatic watering system - worked perfectly for 15 years :)

Also, for the sake of testing for corrosive off gassing, I’m not saying they don’t off-gas, but for ad hoc testing purposes I’d flattened out and taped a strip of silver solder inside the roof of the vented battery box as a improvised sorta coal miner’s canary idea, but over the years I never saw any signs of silver discoloration whatsoever, or on the terminals! - this may be due to the compartment door’s venting…

At least that was my own experience, however I’ve since switched to LiFePo4 lithium and have been extremely pleased…
