afternoon, I am experiencing a battery issue that supports my generator. We replaced the battery last August and after it was working fine. This year the battery again is not charging or draining and has failed. The other batteries on the boat are charging when the shore power is hooked up.

Identify the year and model boat.

It may be that the on board AC/DC battery charger has partially failed. It may be that the wiring is wrong or failed. It may be that the OEM charger has been swapped out and the replacement doesn't have an output for the charger. It might be that the replacement battery is bad, but that is not likely.

A quick check is to measure the resting voltage on the battery banks after the charger has been operating for an hour. The battery voltage should be about 13.8 VDC in that condition.

More info is required.

Thanks for your quick reply, I have a 2001 34 ft sea ray sun dancer. I agree I may not be getting a charge when on shore power to the generator battery. I do need to put a charger on that battery then test the charge as you stated. I believe it should be charging as the others are. Your assistance is appreciated.

Wow, that was a mouthful.

To be clear, my suggestion is to not add anything else to the boat, just plug in shore power like normal, let it remain plugged in for an hour, then measure the voltage on each of the battery banks.

Captain_Zero · ‎05-27-2017

I do not believe that the engine deep cycle batteries are maintained with the inveterr/battery charger. So as wngless pointed out may be a bad inverter assembly. If I am incorrect on inverter maintaining the deep cycle as well while on shore power I would run two new wires from the starting batteries for the boay.

Captain_Rick1 · ‎05-28-2017

AJB. Let's bring this back to reality. 1. Turn off shore power to your boat. 2. After letting it sit for 1 hour, take a Volt meter and measure the voltage in the suspect battery - you should get a reading around 13.2 - 13.8. If so you are good and you probably have a bad ground. 3. If you do not have 13 or so volts then now it's time to check the charger. 4. Turn shore power back on - make sure charger is on at the breaker panel - take the volt meter and measure across the OUTPUT posts on the charger. You should get 13.8 volts. If not -your charger has failed. Do these test and PM me with the results.

According to the Lifeline Battery Technical Manual reality, page 32 of 40, a rested fully-charged aged battery will measure over 12.78 VDC and a fresh battery will typically measure 13.0 VDC.

Two simple steps, get a hydrometer and check each cell. If all cells test good, borrow a load tester - remove the ground cable and load test the battery. At least this will tell you if the problem is the battery or the charging system. It is quite possible to have the battery put out 13v after a full charge, but that does not mean the battery is good as does the fact that the battery is only a year old mean it is good.

Captain_Rick1 · ‎05-28-2017

Load test is a good idea to include if the battery checks out voltage wise. No need if it doesn't hold a charge.

SeaMax · ‎05-29-2017

The load test is to determine if the battery itself is good or not. It will not identify problems with something in the system causing the battery to drain or not holding a charge. As suggested, the load test will tell you where to look, either the battery or something else in the electrical system.

Thank for everyone's assistance on this matter. I checked out the batteries and they are now reading 12.85 which is good. Not sure if a had a loose connection but after checking all of them the system is working.
Thanks again for your assistance.

Clean your battery connections too. A bad ground will also give you that symptom
