My two Wallyworld group 27 marine/rv batteries lasted 11 months. I checked the water every month and never had to add any. They still don't need any water added.
The 12v lights got a ittle funky one morning, I checked the voltmeter and saw 10.5v (!) and of course there was that nice smell in the compartmnet.
The batteries looked fine but both had a little water on top. I yanked out the easiest one to get at, and in short time the other one was almost 12v and climbing. It went into float at about 13.1v The other one sitting on the ground showed 11.8v the next day.
I got another battery and installed it as a single; it's at 13.1v. This is liveaboard usage every day.
So...my previous Interstate group 27 marine/rv batteries lasted six years even including a couple of instances of abuse. The Wally batteries, ostensibly the same, lasted 11 months. Hardware and usage is the same.
