They take a licking and keep on ticking...
I did my regular battery maintenance today on my Costco 6v. SG was 1.275 to 1.28 on all cells with a +3 for temperature (1.283). I have a quality float type hygrometer that is probably 30 or more years old and generally corresponds to a cheap one I also own.
One battery needed about 1/8" of water and the other was OK.
I installed these battery on my previous trailer. I noticed the manufacture date sticker on the battery and it read 8/08. That makes these almost 8 years old.
On my previous 95 Terry, they were charged by a standalone no name charger with only a single voltage unless you flipped a manual switch to boost to 14.4. I did that occasionally before a trip.
Next, they moved to a '11 Wildwood in May. Yes I had the Terry for 15 years and then sold it to a friend who still has it.
For the first year, the batteries "survived" on a WFCO. In May of 12 I bought a PD60 from Best. They have mostly been maintained by the PD since then. I kept the WFCO installed as a backup if needed and sometimes I forget to plug in the PD after a trip. It's wired separate from the trailer circuits.
I amazed at the longevity of these batteries and expect that they may go another year or 2.
