3 AAAIt comes with them.I use one on my stairs in my home. I have another near the entrance to my goat pen and another out near where I have my garbage cans. The light is on for less than 30 seconds. It alerts me when there are coyotes near my goats and on my stairs, I never turn on my stair lights (I also have one on the outside leading down to my cellar). I have replaced one set of batteries in about a year (on my stairs) and have not replaced the others.I hope that helps.

I believe one of the lithium ion batteries - but not sure which one. Still using the one that came with it.

It uses one CR2 Lithium 3 Volt battery. They cost a little over a couple of bucks apiece.

I have no idea. Sorry. All I know is that I've been using it for half a year and it works like a charm. Still gives me more extra hours than a regular battery.

As Dana B. answered, the battery is built in. It is a Lithium Power battery. I have been using it for several months and it is adequate at best. The battery lasts a goodly amount of time.

I don't know. Just run a search on your camera and it'll say what battery it takes.

It uses one battery of two battery types. It uses either a standard 1.5 volt type AA battery available at local stores or a 3.6 volt type 14500 Battery that is rechargeable and available from Amazon with charger. Rechargeable AA batteries can be used and are available at many stores. I use the AA battery and get good brightness and life. The 14500 would probably be brighter but it is a specialty battery.

It uses a 3 cell lithium-polymer battery, same as what you have in your smartphone or tablet. This according to the manufacturer which I emailed and asked. - hope this is helpful - Paul

It uses a CR123 battery. These batteries are expensive, mainly used in photography. I suggest purchasing rechargeable batteries from Surefire.

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.

It uses 2-AA batteries. I use the NiMH rechargeable but regular AA work also. Using the menu, you select the type of AA battery you are using.

It uses the flat, round CR2025 3V battery. I use Maxell's and bought them here on Amazon. They work great. You can buy them in bulk here that will last you a long time for far less than buying them at your local electronics retailer.

It uses a Sony NP-BN1 Lithium-Ion N type battery back rated at 3.6v and 2.3 watt-hours...

It uses standard AAA batteries. I recommend using the rechargeable variety to save money in the long run.

No, it uses a one of those rectangular shaped 9V batteries. I guess you could buy a rechargable battery of that type if you prefer.
