what battery size does it take?

Either one 18650 lithium battery or two CR123A batteries will do. My favorite flashlight because it is the brightest one for it's size. Plenty bright outdoors and brightness can be reduced for indoors. Nice wide beam. Fits in your pocket. Don't order from China though. I've gotten two pieces of junk from there. Pay a couple of extra dollars and order directly from Amazon. You won't be disappointed.

Patrick the best battery that I have found to use is the Orbtronic 18650 3100mAh all others I have tried have failed after a couple recharges, I have recharged these batteries 14 times and they still charge up to 4.2 V and maintain brightness down to about 2.7 v. I use the light everyday and I swap batteries about once a week. Hope this helps

don't really know. I have an average size battery, fish for 2-3 hours, have never run down the battery.

It appears to only take one size battery. I have a standard replacement battery from amazon and the device works well with this battery. The area where the cellphone plugs into can be expanded by easily removing a cushion lining. I can recharge my cellphone without taking it out of the case.

The transmitter takes a cylindrical shaped alkaline 23A 12V battery. It is very small: approximately 3/8" in diameter and 1" long. I have hardly used the unit since I bought it and, therefore, have not had to replace the battery but I assume that it is readily available.

This is a great tester. It takes a normal AAA battery- approx. 1.75 inch. If they don't have them at your local stores, you're not in the US.

it takes a dime size battery, CR 1620 (one). If you bought it on amazon, and depending on the seller, it should have come with a battery. Good luck.

It takes a 23A 12 V battery. They look like about half the size of a normal AAA in length

It's a Christmas gift, so I don't know how many batteries it takes as it hasn't been opened yet. I checked the box, but it doesn't say. Sorry.

If I remember correctly, it takes 1 triple A battery. I was very dissatisfied with this product. The hydrometer did not work. Ever...

Sorry when I answered your ? I meant to add that the 2 AA batteries are NOT included. I figured you knew that, since you asked what size it needed.

I believe it is C size battery. I own the unit but I am using the AC not battery.

It takes batteries- I will have to check which size, but we have not had to replace the batteries at all so far.

It takes a 23A. Looks like a short AAA but it is 12 volt. I have found them at Walmart.

for the 18,000mAh it takes almost 24 hours (from empty to full). When I know I'm going for a trip, I plug it at 8PM (at this time, the battery is EMPTY totally)and it's usually finishes at around 8 AM (almost, sometimes half an hour more is needed)

This item uses one N size battery (1 included). Thank you for shopping with Vert Delivery!

It does not take batteries. You need to find a power source that connects via usb cable. Look up usb power source
