I have a house bank of 3 gp24 deep cycle lead acid batts installed in mid 09. They are now 5 yrs old. They live under the quarter berth, which is poorly ventilated and makes access difficult for servicing. It is nerve racking to stick your head
in this space, slide batts around , pop off the tops and add water
with a baster and hope nothing sparks...
Wm agm's go on sale
next week, something I have never seen. My batts now are charged with a full time 20a multi bank charger
, with all 3 outputs looped together sending all output to house bank. I also have 1 maint free lead acid starting batt that only gets charged by alt or occasional car batt charger
. I now I will have to change the setting on my multi bank charger. Also, sometimes when running engine
for long periods I will set batt selector to "both" thinking this is sending alt charge to both the start and house batt's.
Questions 1. with batt switch on "all", does this send charging current
to both banks. 2. Do AGM's require much less service
than the lead acid batts 3. what am I overlooking?
