Battery charges

I have seen these low amp type battery charges for sale, I believ they connect to the batteries permanantly and you just plug them in and turn them on, the battery leads and such remain connected etc, they supposedly keep your batteries charged between uses with out taking them out to charge.

Can anyone advise me on these things I always thought you had to disconnect the batteries before charging them.

Thanks

G'Day, Have always wondered about the disconnect before charging. Does turning off the main isolater acheive the same thing?

You don't need to remove the battery or the leads to charge it. It's a good idea to isolate the circuit if you have an isolator on the battery terminals or in the boat. Just connect up the trickle charger to the terminals. There will be no circuit going through the boat or motor and the battery will charge up fine. I have been doing this for years.. No problems.

They act the same as a solar charger, I have plub in 24/7 and keeps my old battery topped up at 12.6V. The voltage will rise to about 14V on a sunny summers day.

All but my 27MHz is isolated via a switch panel (radio direct if i loose the switch panel or switch save a re-wire on the water).
