Unfortunately, I have used my 28' S2 very little this year. I thought
I had checked my battery water but now I remember the last time I
checked was in January and I have a solar panel that keeps them
charged and probably overcharges them causing them to lose water. The
problem is that the battery location makes it very difficult to check
them, especially in summer when it is so hot.
Now my batteries are dead after only 3 years of use. So, what are my
best options? I am sure maintenance will continue to be a problem but
I really did not think my small solar charger really caused problems
but clearly it did. I have it connected to #1 only and that one had
almost no water. #2 had more water and does take a little charge but
should also be replaced.
Are maintenance free deepcycle batteries worthwhile?
Any suggestions?

There is this on ebay:

Item number: 250147313014

which I have been reading up on. Seems reasonable. Has anyone had
experience of Desulphators?

Are you all the same voltage batteries? Reason I ask is all 4 of my
Trojan 105's boiled away - twice in a month! On replacing them and
reading the charger manual (Xantrex) it quite clearly states that
battery voltages mustn't be mixed. Turns out I had 2 X gel 12v and 4 X
6V wired up. (Wired up by previous owner). I now have all batteries at
12v and shouldn't have a problem.
