I don't know the exact specs but I can tell you that it lasts about 2hr of medium to low league of legends, 4 hours of HD Netflix and negligible decrease over two days, one night of sleep mode. I wouldn't suggest gaming on the thing I only did because my friend begged me to

It is a size EPX 76. You can buy them at Walgreens, Radio Shack, etc. Typical watch/small electronic battery.

7 1/2'' by 4". Unless you need to keep a lot of cable and wires with you. You don't need it. Mine stay home 99% of the time. The EasyAcc battery goes with me everywhere.

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.

I'm going into my 4th year with it and the battery is still fine. I use it about 40 times a year for about an hour each time. It's about 10" wide x about 14" tall x maybe 6 to 8" deep. The smaller pack is about 4" wide x 5 or 6" tall. Sorry I can't be more exact, I'm not home with it now to measure it.

Well I can't remember battery size but it's a tiny button like one that would go in a stuffed animal. And you press it and it plays and stops on it's own until you press it again.

I looked on the battery and there is no information. I don't seem to have the literature that came with it. Sorry.

mn21/23 12volt (its about half the size of a triple a battery. not sure if mine is defective or not, but ive gone through sets of batteries and they don't seem to last or work well. the light it gives off was sufficient, but I wouldn't buy again.

This was a gift to a grandchild in another state and I have no idea what size batteries it takes. Sorry.

1 D size battery in the model I have. The battery lasted all summer with intermittent use.

The picture of the "29" battery is deceptive. It is distorted and looks squat. I just carefully measured it and it is exactly 1-1/4" wide by 2-1/8" in length.

Best as I can tell these are the dimensions of this battery. I have two of them.

The internal battery died years ago. Have been using a mini USB phone charger since. Have also powered the device through usb hub. The device lays on my truck dashboard. Device is about 2.5" x 1.5" x .75" going from memory, as I am not at work today. Could be more precise later.

It's a round disc battery the size of a nickel. A hatch opens in the rounded back to replace the battery.

Battery size AA. And the mics I have are very stingy about draining them fast.
