I also have the Dolphin chargers 2 50 amp units. I use them in
combination when I charge with the generator and a single unit when I
am on shore power.
If your unit is similar to the one that i have there should be a
selector switch that allows you to choose the type of battery that
you are charging. If you select the GEL setting it will charge at a
higher voltage and a higher amprage. BEWARE when you hook into shore
power make sure that you put the selector switch back to the setting
for wet cell batteries. Because if you leave it on GEL you may run
the danger of cooking the batteries. I learned this the hard way.
However, if you use this feature to slightly overcharge your
batteries say 8 to 10 hours this will help condition your batteries
and help them hold a higher voltage.
Its also important to monitor the the amount of amps that your
battery bank is accepting as well as the voltage. There is much
information out there on this subject.
Hope this helps

needed to replace my current batteries. I did that in St. Maartin,and

batteries, new charger same old problem.quits.
I just talked to Rolls Batteries, and they said I needed to be ablede-
sulfate the batteries.As
soon as the charger is off line the voltage drops to 25.6 andstarts
dropping until I charge the batteries again. Currently I must runaamps.
have talked with Denis at Dolphin and it does not seem that my
