Clearly I don't know. The problem is that my battery boxes are under
the sole and have no venting. I wanted AGMs, but the only thing
available in Guatemala was lead acid.

The best bet for deep cycle batteries with difficult access are the
Rolls or Surettes with the recombinant caps, also known as HydroCaps.

Supposedly the cell caps contain a catalyst which turns escaping
hydrogen back into water if my understanding is correct.

If nothing else, they have a great warranty.

Thought you were in the states right now for some reason.

There is a Rolls dealer in Miami that offers good discounts.

I just bought a standard 8D at NAPA auto parts for $160 which
surprised me as being fairly reasonable. It goes into a difficult but
not impossible location, so it does get checked and refilled once in a
while.

Unfortunately these are sealed lead acid and can't be tested with a hygrometer.

I thought SLA should not be equalised - taking them above 14.4 volts
will have them gassing without any way of topping them up??
