Onboard battery charger question

That's a great idea. I had not thought of that. The charger was primarily
for the trolling motor battery because the engine took care of the starter
and accessory battery. Having it charge the engine battery was a bonus.

Thanks,

Jeff I did the same... But I never charged the Motor Battery as my engine
always seem to recharge it.I hook up my charger to each Trolling battery.
I
have never had to charge my engine battery once,unless your listening to a
radio or have alot of stuff running

In my boat, I have a dual onboard battery charger. One side is
connected
to
my engine battery. The other goes to my trolling motor battery. With
regards to my trolling motor, what happens if I hook up another battery
in
parallel to my trolling motor battery? My trolling motor is 12V and by
hooking up in parallel, I still have 12V.

My question has to do with how the onboard charger from one side would
charge those two batteries hooked up in parallel. Is it possible that
if
one battery is not as full as the other, that the charger would "cook"
one
battery too long? Keep in mind that I am only talking about the two
batteries hooked up to the second output of my charger. The first
output
is
hooked up only to my outboard battery.

Thanks,
Jeff
