The base is power by an A/C adapter and the 2 wireless units use a 9 volt battery. If I recall correctly they came with a 9 volt battery that had enough charge to test the units with.

I have two new units and had two old units. As far as I know, the new improved batteries ARE the default batteries. The old type in the black aluminum cylinder housings are a thing of the past and should be long gone.

There is no internal battery. It's basically a portable power strip / surge protector so it will only work if it's plugged in.

A 9v battery was included with mine, although a cheap chinese brand. But it has worked well so far, about 1hr plus of occasional usage and a complete check of a 3500 sq/ft business.

Hi Lorraine, the best I could find for your answer on battery type is an Energizer 2032 battery -- CR2032 Lithium 3v. The units I had gotten were not for myself. I know they were a type of button battery. I found this info., way down the page for the bigger pack of these units, also being sold on Amazon, in fact these batteries are sold on Amazon. The unit I had bought came with extra battery's. Hope this is of some help and not to confusing. D.

1XLR54 battery type. Its solar (office lights work fine). The one I have I've had for 9+ years and haven't had any issues with it (used regularly at the office).

I don't know the exact battery type, because it is a sealed unit, (probably nickel-metal hydride (Ni mH)). It does not come with a "spare" battery, just the one in the unit when you buy it, and this battery does ot appear to be user-replaceable. It charges through the supplied cable to a USB port, or if you have one of those adapters that charges USB devices directly from an AC outlet.

Model#3089 takes a 23A, 12volt or 3LR50 12volt battery... It's a "security" battery. I found a replacement for it at Radio Shack.

Mine uses 1 D-battery. I used it a few times last summer, but haven't put it out in the sunroom yet this season. The battery never died last summer with intermittent use (mostly on weekends when the family was out by the pool).

It uses a CR2032 nickel battery. The battery comes pre-installed. I've had mine for 7 months now, and the battery shows no signs of wearing down.

It uses a CR2032 battery. I have not needed to replace my battery yet, but looking at the unit, I see an access plate on the backside of it. It can be opened using a coin. Replacement should be very simple.

A cr123 3volt battery. They can be pricey if purchased one at a time but reasonable if purchased in bulk.

AA batteries are used. I keep the main unit plugged in via the power adapted that came with it, but if you're looking for portability of the base unit then use the AA batteries.

I don't know that specifically, but I do know the unit works very well. After it was charged thru the AC, the battery still shows power over 6 months later (only minor usage of the radio and flashlight features during this time) I really like it and recommend it.
