Battery Tender Plugged into Marina Shore Power

[pfegan11]

Hello Everyone,

First time boat owner and I have a question about using a battery tender plugged into a marinas shore power. I have a 2003 Super Air Nautique Team Edition and am going to be leaving it in a slip at a marina during the summer. I have read through these forums and the best solution seems to be leave it on bilge pump only mode and leave a battery tender plugged in. No info however on plugging into shore power.

The marina has standard 30 amp power. So batter tender -> extension cord -> https://www.westmarine.com/buy/marin...35?recordNum=8 -> shore power ? Is this a safe / my best option?

Right now my bilge pumps turn on and run constantly, but that is a separate issue. I need to pull them out and clean them first before making more guesses as to why they wont turn off.

Here is a picture of the boat just for fun. This is from the listing so I don't have the luxury of the large garage the previous owner did.

That should be fine, but I would still check on it at least every week or so, just to be sure nothing has gone wrong with the charging or the pumps.

As long as your "tender" is a multi-stage smart marine on-board charger, there is no issue. All those boats in the marine are doing the same, but with greater loads.

Do I need something more than this weatherproof option from Battery Tender?

Your bilge pump system should have an "auto" mode where the pump only stays on if it is pumping water. If the bilge pump remains on all the time, then you have a problem that needs to be addressed. After that, a Battery Tender is a good choice to keep the batteries properly maintained at full charge while plugged into shore power. No worries there.
