I know the voltage is higher, but are these the exact same PHYSICAL size as a normal AA battery?

Yes they are EXACTLY the same size as a normal AA battery. I COULD NOT USE THEM as the battery I needed was shorter in length. (Part numbers were identical).

They are not a normal size battery. They are all over larger than AA, more like a longer slimmer C battery. They are very specialized for specific items. All the information provided on the battery is in the name: BRC 18650 3000 mAh 3.7V li-ion made by UltraFire.

These batteries are comparable to AW imr batteries. I use these for my vapes and have no complaints.

The batteries are standard diameter 18650, but have the extended button tops which may be long for some flashlights. Not sure on your particular flashlight, but they still fit in mine even with slightly longer overall length.

I have used the replacement batteries several times with recharging them. So far they are working flawlessly. About the same weight and definitely the same size.

Same size as standard AA batteries. However, some solar lamps DO take shorter batteries.

The physical size of the battery is about the same as the original. But mine wouldn't hold a charge for very long.

That's a good way to put it...yes.Overall, they are like oversized AA batteries. They do, however, hold a charge very well...especially for things like tactical flashlights, etc.

It depends how you are using your batteries. If you are planning to use them as a drop-in replacement, then no. They are the same length but a lot thicker. They are the same voltage but higher capacity.

While the two batteries are both 18V and look rather similar, physical dimensions wise they are not identical and most likely cannot be used interchangeably.

MY answer was AA, They are not AA just similar in size AA would be 1.5 volts@. These are a little larger and are 3.7 volts @. Sorry for the confusion, Hope this clarifies the issue.

The batteries aren't by APC, but they fit correctly and seem to work fine. I've replaced a couple with success. They look the same, are the same dimension and have the same connectors. All is good from my end.

Yes, they are the same size. Now the 4000 mah with over charge protection are slightly more round. But the standard 4000 mah are the same size as the 3000mah.

They are about a mm shorter than standard AA. I have had problems in many devices.

I i am out of town so can't grab my battery but yes they are physically larger then a standard 9v. A standard 9v slips in and out of my paintball gun with easy but with these batteries it grabs hard enough with these batteries to require me to use a flat head screw driver to pull it out enough for me to grab it firmly enough to pull it out.

No, they are much bigger. These are good batteiries for things like a flash light, book light ect.. but not for what I was looking for. They are not the same size as AA.

Hi Joe, These rechargeable AAA sized batteries are the same size as regular Alkaline AAA batteries.
