Charging a battery? Can this unit charge a battery I have a camper with a 12 volt battery was wondering if this would keep the battery charged or charge it up as needed

Actually if the camper battery wasn't run down too much, yes the internal charger could charge your battery. I would start with this unitt being fully charged and you would of course need a power outlet nearby. I don't think I would use this to do this on a regular basis but in a pinch it would work.

I went with 12v battery with solar charger. I made my own out of ammo can instead of buying one. Battery stays full and don't have to keep buying batteries. I used a old charger cord off regular 12v recharger. To hook to unit. Works like a champ. Only way to go in my opinion.

I would recommend getting a electrical charger. This one is more for something that you don't drive very often like a atv or a lawnmower. This only being 2.4 watts, isn't powerful enough to charge a car battery. It's really just for maintaining. I bet it would take a long time to fully charge a car battery.

This unit needs to be connected to a battery and it will charge the battery. The amount of time will depend on the amp hours of the battery, how long you use you devices and how much power/amps they consume.

No, you provide a 12v battery source. It would probably run for a long time on this battery, and you can get a cheap trickle charger to charge it: UPG UB1280I Sealed Lead Acid Batteries

Had mine on a 12 Volt ATV battery for 4 months . Does not seem to be any problem. It charges so slowly I don't think it could hurt the battery. But does get the job done. Hope this helps.

It cannot be charged up at all. This unit runs on two AA batteries. When they're dead, you throw them away and install new batteries.

If the internal battery is drained then unit will not work correctly until the internal battery has some charge. I have tried to plug the unit in to the usb charger after the battery drained but then had to wait some time for the battery to charge before it would work right. I suppose as long as you keep it plugged in to a usb charger all the time then the battery will stay charged and so should work.

That's the idea behind any type of battery charger AC to DC. If I understand your question properly, you have the Tender plugged into a regular AC outlet and are charging a 12v DC ATV battery. It will work just fine.

I have this unit for charging my HD Road King while on the road. If there is an available electric plug, it's great to be able to top off the battery overnight, especially if at a campground. One day, I forgot to turn off the lights, and the battery went dead. It took a solid 3 days to charge the battery due to the low output of this unit (my normal Battery Tender would have done it in a day).

I bought this got my camper. Works great with 2 batteries. Not sure it would keep your trolling battery charged if you're using it frequently. If your boat charges batteries when running this might keep them topped off for you when sitting at dock.

The answer is Yes and No. Any 12 volt charger will charge it, but must have the right size "Spade Lug" connectors to mate with the battery terminals. Or have an "adaptor cable" to convert the typical 12 volt charger cable connector to the battery lugs. Be careful to use a low current charger adaptor, not a car battery charger.

Be very careful with using this unit, it does not keep a constant voltage. Mine is about half of what the toggle says. ie I have to put mine at 12 volts to charge my 6 volt radio. At 6 volts it is putting out 2.5 to 3 volts. I would not recommend this one.

I advise u not to charge it with a different charger b'couse it may cause defect on it . The battery can support a certain A or volts but it was designed to measure when it's full charged or empty , what i'm trying to say it's u can short the batery life if u use the wrong charger .

You would need to put two 6 volt batteries in series (make it 12 volts). Not enough info ?? eg: is this automotive type battery etc. As is not made to charge 6 volt battery.

This unit comes with a built in charger (that charges the unit only) and it is a regular 120v plug in. I hope that answers your question. This is not meant to recharge batteries. This is meant to boost an already weak/dead battery to start it's engine.

It would charge in the car but the car would probably have to be running to keep the current going. It doesn't work without being "plugged in." The first camping trip I took it on the timer/delay broke. Cheaply made. I cut the timer completely off. I have rigged it up to attach directly to a small battery and slept very warm. So it does work pretty good now.
