Battery charging

I have an onboard charging system, 3 bank 5/5/5 amp. If I leave it on it boils
the water out of the 2 deep cycle batteries but not the starting batteries. I
have never had to add water to the starting battery. anyone else had this
problem...Thanks

I gave up on onboard chargers. They are ok for heavy use when out of town
stretching an extension cord out the window of your motel rooom, but for
regular maintaining I prefer automatic float carry chargers. I use a 2/4/6
amp Black & Decker I bought at Wally World. I've got five of them now. I
figured when I have a couple extra dollars I'ld go pick up a couple more to
have spares on the shelf. At 29.95 each I can buy a lot of them for the
price of one 3 bank on board charger.

I just had the same problem a few months back, I had some 24 series
everstarts and my onboard charger cooked them, now I have 29 series and
I disconnect them as soon as the green charge light comes on. I think my
charger failed to just trickle after they were fully charged.

Hi,
I have never had the opportunity to use an onboard charger. That said
I have never put a battery charger on any battery I have owned without
a timer in line.

With deep cycle trolling motor batteries I tested them while charging
enough to learn about how long to charge them for the amount of use
they had.

A timer, specific gravity tester and the time spent learning how long
to set the timer for is well worth the cost of a set of 2 or 3 deep
cycle batteries. You never know when a charger will fail and cook
your batteries. With a timer it just doesn't matter if it goes to a
trickle or maintain mode. When the timer turns off the batteries are
safe!

For long term storage a week long timer can be used instead of a 24
hour model.

Cheap insurance.
