I have a 12 V battery backup sumpump. is this charger is good to charge the marine battery connecting to the pump. Also i do not know the amp for the pump.

Exactly what you need. It's a Solid state trickle charger and will keep your battery at full capacity without over charging and damaging it. Pump amperage doesn't matter, as it will run off the battery in backup situations. This charger only maintains your battery at full charge. Got 2 of them on my boat, work fine.

This charger will charge any six (6) or twelve (12) volt battery. It is not the type of charger you would leave inside a boat for charging. If you remove the batteries from the boat or charge them in an open area where there is no possibility of a fire or explosion you will be pleased with the results. I use them for my boat but I stay right with the batteries and charger while the charging takes place. In general, this is not a Marine charger that you would install in a boat. I have several of these chargers and have been extremely pleased with the performance and when I required any information or help, the Factory was very helpful. I hope this answers your question.

I used this on top of a Chevy Suburban to charge a battery which runs a pump that is independent of the main battery. This way the risk of draining the starting battery was zero. It keep the battery at full charge

It may not get the battery to a peak of 14.4V, but it will get it to a close to full charge condition. However, remember this thing charges at about 1 Amp. For a Marine Battery, it will take a long time if it is discharged. It will work fine if you are only trying to keep it at full charge.

Sorry, I just saw your question. I would NOT recommend this battery charger PERIOD. I ordered two of them and they are cheap and don't work.

Yes. This charger works 3 batteries. For my setup, I have for my boat a marine cranking battery. Then I have 2 full deep cycle batteries for a 24 volt trolling motor system. I used to charge them one at a time which was a major pain. Plus I never realized that with the primary cranking battery, running the battery off the alternator once running will not fully charge the battery. It will only get to about 70 percent full. However with this battery charger, it has an internal computer which will properly charge and maintain the battery. The other good thing about this charger is that if you only have 2 batteries, you can still use it. Just pair the other free connections to one of the batteries. I contacted ProMariner customer support directly and they confirmed this is possible and safe. Overall happy with the product!

I don't have experience using it on paired batteries. It sounds like it becomes a 24 volt system when paired up. I have a boat with paired battery banks it uses a much more powerful charger for them. However it will work well for your main engine battery by itself. You may need a 24 volt charger if it's paired to 24 volts.

Those chargers are meant to "maintain" a charged battery. They don't do much to charge a discharged one. Get a small charger and hook it up to the battery to keep it charged. I use a Deltran Battery Tender Plus on mine. I leave mine both hooked up at the same time. If totally discharged, you may have to use a car battery charger to get the battery recharged. Periodically hit the test button on your pump to make sure the charge is holding.

Yes. My boat has an automatic on-board charger. Any 12volt automatic charger will work.

I'd like to use this inside my sailboat cabin. Seems I should be able to put a 12v adapter onto its plug in order to use with my marine battery. Does anybody know if this sounds feasible?

Yes, I have mine attached to my battery in my boat 24/7 (at least in the summer) and use the boat at the same time. Don't expect this charger to come anywhere close to charging your battery while using the trolling motor tho. Connect it and forget it.

yes . i use mine often on all types of lead acid batteries, mostly associated with boating, fishing needs including deep cycle and maintenance free batteries. i purchased this same charger earlier and was so pleased i got another one for a different location. both have always worked very well !

The question posted by Barbara Kennedy was "how fast does it work?". This is a battery maintainer or float charger. It is not suitable for recharging a depleted or drained battery so charge time is not normally discussed relative to this product. If you need a proper battery charger there are many better suited to the task than this product which is aimed at keeping full charge in a battery that is used in a vehicle which is not frequently used.

It connects to two 12 volt batteries inside a boat . Its called a onboard battery charger because it stays inside the boat and you just have to plug a extension cord into it at the back of boat. It will charge one or two batteries (24 VOLT system).

It is a very good charger, i us it on only one 12v battery currently, but i see no reason why it would not maintain the charge on your batteries as long as they are hooked as a 12v system, i am sure it would be more effective it you did one at a time and cycled them through

Yes, no problem. Of course, the trolling motor should be turned off or it will draw more than the charger can put out and your battery won't get charged. But this is a fine charger for "on-board" use, meaning mounted permanently in the boat or raft.

find out what is the amps the pump will draw and get a converter of that value or larger. I believe most any battery charger would power this pump also for a temporary set up.
