Checking the water is impossible when it's installed.


when I shoehorned the two GC batteries into my camper storage there was only about 1/5 to 2" above them, so no way to fill them. I bought one of these and its the best things I have done. I even got one for the 5th wheel that I have lots of room as it makes topping off the batteries so fast and conveniant.

Marty,

Colder is better for storage. The self discharge rate becomes slower dropping by approximately 50% for ever 18 degrees lower temperature. (10 C). I had 7 group 29 jars. No way would I ever consider removing them.

If you stick with the basic & the cheapest, group 24 wet cell, you will always be tied to the post.

As a few have suggested cram as many amp hours in the space available as you can. That will likely be only a pair of GC batteries or maybe a pair of group 27 12Vs if you are lucky.

You might be able to do a single 4D case sized 12V.
