Can batteries be charged through this unit?

No this was the worse charger. If this is the type of quality Neewer company has has to then I would stay away. Instead of charging my battery it drained it. Furthermore I had to replace my battery on my phone because of the drainage this charger did. Just awful. Let me repeat awful. Did I say awful already?????

No. This device is SUPPOSED to charge a device that is plugged into it and runs on betteries (2 AA). It does not charge batteries.

No. Beware it will drain the battery that you are trying to charge if you leave it attach too long. Don't know why but that's what happen to me trying to charge a small phone. It charge the phone for 15-25 minutes(Had 2 bars of 4) but 45 minutes later the phone was back to no bars.

Short answer is "no". There are two wires coming out of the unit that you can basically connect to the terminals of a 12V battery (I used a car battery). You'd need to get a 12V power supply that plugs into the wall and hook it up to that if you wanted non-battery power.

It looks like the batteries have to be removed to be charged (which makes me question why it's called 'rechargeable'?) The plug cord is removable and works fine - but only to power the unit directly. (as I understand it)

No. The unit is powered from a permanently sealed battery with 10 year life and cannot use external power, so there would be no point in doing so.

Yes you can. The charger is designed to recognize a full charge and then will trickle charge so that the batteries stay charged and ready but not overcharged. I am doing the same on mine

You can charge the battery through it. The voltage is set by dip switches on the unit. Handles 12 or 24v

Plugs in and takes batteries. I guess you could use rechargeable batteries, but unit will not charge them.

Yes, but it has been known to ruin batteries. I would suggest that you buy a multi-chemistry charger as soon as possible. There are several decent chargers between $50 and $100

No, the batteries charge in the unit and it has a car charger. You could use 5 traditional AAA batteries as well.

You can, it will not fry the batteries. It will only charge the batter if it needs charging.

Yes it can be charged if you have an ac adapter. (None supplied with initial purchase). I do not know how long the battery charge last but think that would depend upon how many times the unit activated from movement, which is not predictable.

I have never done this however I googled the question and a few sites said yes, many people charge batteries this way.

Yes you can. It takes awhile to charge unit but charges others 5x before unit needs charge.

Yes you can power the system by battery. Just be sure to use fresh batteries when installing them. The unit will have a visual and audible warning when the batteries are getting low to warn you to replace them.

It unit has an internal Lithium battery that you charge with a usb cable. Not replaceable.

No and just so everyone knows this will not charge rechargeable batteries if you do decide to use them. We use rechargeable batteries and they do not charge.

No, the batteries can only be charged in their specifically designed chargers.
