battery charging question (possibly dumb]
I just bought a Die Hard automatic battery charger today. The
instructions say that "a marine battery installed in a boat must be removed and charged on shore." The instructions indicate that it is okay to charge a car battery while it is still in a vehicle. My boat is in my garage. I think that it is okay to charge my boat batteries while they are still hooked up to everything. It sounds like the instructions are meant to not charge boat batteries while the boat is in the water. I just want to be clear that I am not hurting anything by charging the boat batteries while they are still hooked up. Also, would it be best to use the 10 amp or the 2 amp charging mode? It doesn't sound like I can just leave this charger hooked up all the time, so I guess I should just use either mode and disconnect when fully charged. |

It may be that the manufacturer is worried about sparks when you connect the charger. I take mine out of the boat for charging. I put my charger on 2 amps and will leave it for a week. Then I'll transfer the charger to another battery. The charger is automatic, so it won't overcharge the battery. -- John H **** May your Christmas be Spectacular!**** *****...and your New Year even Better!***** |

I would expect those to disperse in a car battery but in a boat could collect in the bilge and cause a really dangerous condition. Anyone? |

With there being on-board chargers, I wouldn't think that would be an issue? Also, does an outboard motor charge the battery while it's running? |

The warning is probably a protection from a suit when the charger fell in the water, or somebody electrocuted themselves while handling the charger from a wet surface. I charge mine in the boat when I need to. I have a Vector 1092 and works fine. As to hydrogen collecting, there should be enough ventilation to avoid collection of large amounts of gas. |

On-board charges are permanently connected to the battery. A conventional battery charger is not, so it will create a spark when it is attached. Outboard motors do charge the battery when they run but, just like a car, the alternator can only produce a fixed output. This is typically enough to keep the battery charged but if you have a lot of drain from accessories, they may be more than the alternator can handle. Dan |

That's another reason to run the blower for 5 minutes before cranking the engine. I don't know if the fumes from a battery are heavier than air. -- John H **** May your Christmas be Spectacular!**** *****...and your New Year even Better!***** |
