If one or more batteries were low/discharged when the boat was put away for winter, they have likely not survived the winter and may need to be replaced. As to the on-board charger, yes, you should be able to plug it in/turn it on what ever the case may be, and have it charger the batteries. However, I do not know to what degree that charger is "smart". Will it put on a continuous charger or will it go into a float mode. This will impact whether it can be turned on and left or if you need to baby sit it. Hopefully someone knows more about how that specific charger operates. |

Thanks Wylie, just to add...the winter here (Las Vegas, NV) is really more of an Ohio summer...never really got below freezing for more than a night. |

I love Jan weather in vegas, we usually come out for the CES. Cold temps are only part of the equation. The longer a battery left with less than a full charger, the harder it is for it to recover to a full charger. So get them charged and check them for how well they recover to a full charger and then go from their. |

A 15 amp single bank charger will take a very long time to recover the charge on 3 batteries. It may be time to invest in a newer bigger charger |

I bought a Pro Mariner Pro Nautic 3 bank charger 2 seasons ago by recommendations by another member here. It's a GREAT little charger. I think it was about $250 or so, depends on the size you want. Amazon has some good deals on them. Also, don't forget to check the fluid level in the batteries before you start charging. I will at least disconnect one of the terminals before winter lay up. I reconnect every so often and throw the onboard charger on. Even though you have the switch off it doesn't turn everything off. The radio still draws for the clock. Or even worse a bilge pump switch could fail and run the battery down. Also, some bilge pumps turn on every so often to sense water. |
