Do I need to disconnect my boat batteries before charging ? For example disconnect from all accessories, Motor , etc. Or can I charge with all of those items still connected.
Do those of you that use Battery Tenders, leave all accessories connected (Above) as well as your Battery Tender, and then simply plug in the Tender/Charger , when your boat is not in use.
For many years I have disconnected everything from my two batteries, then connected a charger to the batteries until I was ready to go out. Then remove the Charger and put it away, and reconnect everything.... Is this really Necessary ?
thoughts ?
No, you do not need to disconnect any wire going to your batteries before charging them, you do however need to have every acc turned off.
I do not leave the battery charger on for more than a few days though, in most cases a battery is charged in one day but I will leave them on for two days if the battery is very low. Some members have stated they leave their on board chargers connected all the time but I don't think there is any reason to do that. I will however plug the charger back in the day before taking the boat out, just to top off ther batteries.
