Charging battery while connected to boat

[loudsubz]

Any dangers to throwing a trickle charger on my battery while its still in the boat. Its not a moomba, its my older ski ray. Its just sitting in the garage right now and I want to make sure it has full power for when I go to start it this weekend.

I don't mind taking it out, its just in an awkward spot and takes some time to remove.

No problem, I done it before.

Same here. I leave mine on my dual trickle charger when in the garage. Leave it plugged in while working on the system. Never had a problem.

Charging both my batteries right now while in the boat. Always have done it no probs.
