SureFire SF18650B Overview

Power small electronics including LED flashlights, lanterns, headlamps, and other compatible devices with the SureFire 18650 Li-Ion Rechargeable Battery.

The battery has a built-in micro-USB port, enabling you to charge it from a wall outlet, power strip, or computer using the included USB cable, eliminating the need for an external charger, with an integrated LED charging indicator. But, if you prefer, you can insert the battery into a conventional cradle-type charging base just as you would more standard rechargeable batteries. The battery provides 3.6V of output power with a capacity of 3500mAh, resulting in a 12.6Wh energy consumption rate to power high-drain devices like LED flashlights for up to ten hours. To protect it from damage it comes with overcharge and over-discharge circuitry.

Will these fit in the Moza Air 2 battery ...

Will these fit in the Moza Air 2 battery compartment? I have read where the batteries that come with the Moza are smaller than standard 18650Li so any other branded battery you buy to replace it will be too big and will not fit. If this battery is sized too big for that product, then is there any other 18650 battery on the market that's smaller than standard size to fit in the Moza Air 2? Because the Moza batteries died on me (and many other people in the reviews section) and I don't want to replace them by again buying the same faulty battery it comes with. Anybody have any knowledge on this unique issue?

A reviewer said the "Power2000 XP-18650 Battery and Charger Kit" here on BH comes with two "short" 18650, perhaps they would work

Sadly this would be too large, you would need a 16650 battery.

Can this battery be used to power NEBO DaVinci flashlights that require 18650 batteries? If not, is there another alternative?
Asked by: James
The SureFire 18650 Li-Ion Rechargeable Battery with Charging Port (3.6V, 3500mAh) is a standard 18650 rechargable battery. If the NEBO DaVinci flashlights use 18650 batteries it should work. Note, it has not been tested on those specifically.
