Does this charger require a controller to keep from overcharging the battery?

No. It puts out so little current that it's unable to bring the battery above 13.2V in full California sun. Even though it's not powerful at all, I like it. It totally does its job when I go on 2-3week long business trips. When I return the battery is fine, while before i was finding it dead or almost dead each time

They mean the controller itself. And since it has an auto turn-off feature, so you won't have to charge it often.

Not exactly it does not have a charge controller. You will need one. It had a cigaret female plug. You can adapt to that. I use to charge batteries for my ham radio equipment. You might look at the deltran solar charger. They go buy battery tender.

If you are hooking this up by itself you'll only want a charge controller to prevent the battery from overcharging. If you are using this to hook up an ac plug in battery charger, then you need the inverter for the charger.

Yes you will need a charge controller, without it you will fry your battery. During hours of darkness it will not discharge you battery.

I tested mine and it was still increasing the charge after it hit the 90% charge point. The rule of thumb is that you shouldn't need a charge controller for such a low power charger, but I think that's not true.

You need to run thru a charge controller of some sort in either case to prevent overcharging.

I don't think you can overcharge the battery with the charger. It has an automatic They last a bit longer than the original one. But not much of the difference.

Yes, it will regulate itself to not overcharge the battery. However, I would personally consider an unattended charger to be a fire hazard.

Yes. Charge controllers, like this one, are specially made to go through different charging cycles to extend battery life span and protect batteries from overcharging.Thank you,AW

No, you need to remove the sleeve to charge. But they batteries once charge do fit with the controller in the silicon sleeve

It would eventually charge it, I wouldn't leave it on any battery indefinitely though as it has no automatic mechanism that will prevent overcharge.

it won't charge it without a battery, but you can keep it plugged in and use the controller without batteries it just has to remain plugged in the whole time.

Hello Kenneth, This is not a charger controller. This is a power inverter. This unit feeds into your battery bank through 12V DC and convert the power to AC for your home use.

No. It needs to be plugged in since there is no battery pack on the controller.

You're probably thinking of a charge controller, not an inverter. And yes, you always need a charge controller so you don't overcharge the battery with the solar panel

I bought an inexpensive charge controller to prevent my battery from overcharging, but it was definitely working without the controller.
