It could be labeled as 2AH. Smaller batteries such as these are traditionally labeled in mAh.

The battery that it uses is the small round one like a watch would use or digital scales. I haven't had them long enough to know but would expect several years from them based on the battery type.

That battery is also sold at most major auto parts. I know for a fact that AutoZone and O'Reillys carries that size battery since it's a common car alarm remote battery size.

The item has a built in rechargeable battery. No need to replace battery, but I do not know the model. That would be a question for the seller.

It uses the 23AE size battery. My battery came from Ebay (5-pack); bought the remote from here on Amazon. So far the same battery has lasted more than a year.

It is an odd size. The battery that came with it is labeled Qianshou alkaline battery, 23A 12V. It looks about half the length and the same diameter as a AAA.

Any size 12 Volt battery. If weight is a problem, use a motorcycle or small engine 12 volt.

The battery is approximately 2x2 inches. Comes with nylon sleeve to hold it and strap on to bike frame. Very light weight, maybe same weight as 5 AA batteries in your hand. It's a super bright light. Comes with headband that is too small for most adults. I only use it on bike anyway. Overall, I love it.

It comes with a Li-ion 3.7V 750mAh rechargeable battery. I don't see any information that identifies what the size or replacement is other than 9019.

The answer is in the name of the battery. It's a 18650, which means it's 18mm x 65mm.

4 or 6 "C" batteries. I can't recall exactly at the moment, but I'm almost certain it's 4. There is also a power adaptor input plug in case you want to mount it near a power source.

I'm not sure but it is a small battery. I'm guessing it is L 7"x W 5"x D 4" I have had it in my bike all winter and I start it once a month and it starts every time without a trickle charger.

Its small round flat battery (3/4 inch diameter about the size of a quarter) that is supplied with the scale (not a typical AA or AAA type battery). We have had the scale for about a year and haven't had to replace it.

It is 6.8, but none of the 2 batteries that I have hold a candle to the Sony one. The real Sony ones lasts for days and the other 2 I have don't hold well at all.

I sent it off to recycling after it stopped taking a charge a few years ago. From what I recall it was around 7x5x3 (not exact). It lasted around 4 years. You could do better with a Li ion or AGM battery today.
