I am single. Would appreciate any thoughts. Just get new batteries or?? and which would be the best. Putting water in the coach batteries is impossible without taking a bunch of connections off.
If the batteries were made in 2007; it stands to reason they were replaced in 2007 or 2008. 3 year old batteries (all things being equal) should still be "good".
Not sure what "2 gals" low means. I am thinking it was a "miscommunication" and he really meant "2 cells" low. Which is a whole other animal. When lead acid batteries charge and discharge, the electrolyte (the water and acid solution) is heated and some water is evaporated. The faster (and deeper) the charge or discharge; the more evaporation occurs. So you should always check the cell water level.
"Low" means you can just barely see the tops of the plates through the filler ports. Dangerously low means you can actually SEE the plates.
Properly serviced is when you can see liquid all the way up to the molded ring made of a circle of plastic, but not to the very top of the case. (hard to explain and I will try to find - or take- a photo).
I do not have a motor home, so I don't know what "storage" does.
Maybe a MH user can help you better. I do know that if that setting allows "parasite" power draw to still occur (the propane detector, radio power, clocks, onboard computer, etc) a few weeks is all it will take to kill a battery; especially if they are weak (or not fully charged) to start with.
