What kind of batteries are these? I'm not sure I have
even seen a "Maintenance Free" deep cycle battery other
than gels or AGM. Maintenace Free batteries are usually
starved electrolyte type and are for starting applications.

I experience a very short battery-life and I want to know the cause
before I install anything new.
The fridge / freezer and other consumers constantly draw power
(between 4 and 11 amp)
I have a 3-stage 120 amp charger (bulk at 14,4,absorption at 13,6 and
float at 13,0)
My batteries are 18 months old. 6 x 180 Ah. They were called
"Maintenance-free". As I understand now that means you can't add
destilled water later on, don't see any advantage of that.
At present my battery-capacity is very low. As I look at it now I'm
confronted with replacing my batteries after 18 months.


Anyone familiar with such problems that (maybe) arise from using the
charger as a power supply during float-charging?

Do I bourdon my batteries by creating a lot of small
discarge/charge-cycles?

Any advice is welcomed for this (surely not unique?) liveaboard-
stuation with 220AC shore-power and use of 12-v appliances.

Thanks in advance, Len.

"Delco Voyager" comes to mind. I bought several of these before I figured
out that they were crap.
