on a boat with two batteries and the battery switch set at both will this charger charge both batteries simultan

No problem. It won't bring a dead set of batteries back quick but will keep the two up if they only need maintained. I have it hooked to several now. Hope this helps.

By theory it could if the batteries did not need to much charging. It is only 800ma charger. I would get a larger charger.I use a solar charger on my sail boat for 1 battery.

It should trickel charge both. It will not charge if one of the batteries is dead. I use it on my 2 boats and a jet ski, but they all have one battery.

Yes it will, but there are other conditioner chargers out there that are specifically made for two or more batteries in parrellel, so you might do some searching before you buy.

With a 12v dual battery setup, batteries are wired in parallel. A single Battery Tender should charge both batteries with no problem.For proof positive, call Deltran (the manufacturer) in Florida: 386.736.7900.

Probably but only over a long period of time and it will only maintain a charge, not charge the batteries up from dead or low.

Hello. You are correct. It charges 2 at a time. I think its a fantastic charger/battery set at this price point. Hope this helps.

Yes, this charger is for (3) batteries. The configuration is normally (1) battery for starting and (2) for accessories. I use all three of these for a special project with all three connected in parallel for more amp capacity and the charger works great keeping all three conditioned and ready.

Because two batteries charge at close to the same rate, and are not identical in their depletion, the charger stops charging the first battery that's full, charging only the one battery that's left. Sounds like it should be able to do only one.

The charger is designed to charge both aa and aaa batteries, in multiples of two. I don't know for sure if you can comingle aa and aaa batteries for charging at the same time.

I'm sure it will charge any battery that it's hooked up to. This unit charges my battery backup system. It's 5 deep cycle marine batteries hooked in series.

Yes, as long as the batteries are close enough to hook the positive clip of the charger to the positive post of the first battery and the negative clip to the negative post of the second battery.

I guess it will work while your batteries accept 14 volts of charge. I have 2 batteries on my sailboat and both are been charged simultaneously. Just check that the coach battery is a 12 volts barttery, for the car batery no problem

Yes this can be connect to two Marine batteries however you must make sure they are fully charged and are disconnected as this is strictly a maintainer.

I don't believe it is a 24 volt charger per se but depending on which charger you have it can charge one or two 12 volt batteries at a time So one 24 volt battery no But if two 12 set up for 24 volt yes

It charges both style of batteries. I have charged my 7.2v 1100mah, 7.2v 1600mah battery and my 8.4v 1600mah NIMH and it did the job with no problems. if it will do those it will charge yours just fine. I have had mine for a year and it still works.

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).

If your 1amp charger is 12 volt AND you charge the batteries 1 at a time. I use my 2 amp charger from time to time.

It will continue to charge as needed. It is a battery maintainer as well as charger. I keep them running on my boat 24/7 all winter long

Yes, But will not charge at 1C rate. Max charge rate when using all four slots is 1000ma. Max when using two slots is 1200ma. i.e. around two hours charge time. Normally charger must put in about 110% of discharge current if battery is in good condition. Really like this charger because each slot is independent and retains values after both charge and discharge.

I would say yes. This charger allows you to leave the batteries on the charger so they have a full charge when you put them in.

Most boat batteries are deep cell which may need a different charge rate than this unit can provide. Contact your boat battery manufacturer for specific charging specs. If you can use this battery tender then you can only charge one battery at a time. You also cannot leave it connected all the time it will over charge the battery after the green charged light comes on. Amazon should sell the Battery Tender quick disconnect lead that will work with this charger. It has 2 large eyelet ring connectors to the battery a fuse and a plug to the Battery Tender Lead.
