What is a 21700 battery?
21700 batteries are rechargeable lithium-ion cells that are used to power various devices like flashlights and vaping accessories. Similar to other lithium-ion cells, the 21700 battery is named after its dimensions to identify size and compatibility quickly. The exact size is 21mm in diameter and 70mm in length.
Is 18650 same as AA?
No, they are slightly larger and have completely different formula. The 18650 battery is a lithium-ion cell classified by its 18mm x 65mm size, which is slightly larger than a AA battery. They’re often used in flashlights, laptops, and high-drain devices due to their superior capacity and discharge rates.
What is the voltage of a flashlight battery?
For a flashlight, you want high discharge rates (3.7V-4.2V) and lots of maH (more than 1500). These things aren’t necessarily easy to find on common cell boxes, but you can find them if you need to. Most alkalines are 1.5V. Most camera batteries are 3.0V.
Can I use 18650 instead of CR123?
There is no brightness difference between CR123’s and an 18650 rechargeable. Rechargeable 18650 batteries will typically last longer, but do the math for the batteries you are considering. Keep in mind CR123 batteries are typically cheaper than rechargeable 18650’s, but two CR123’s equals one 18650.
What is an AGM battery?
AGM or Absorbent Glass Mat is an advanced lead-acid battery that provides superior power to support the higher electrical demands of today’s vehicles and start-stop applications. AGM batteries are extremely resistant to vibration, are totally sealed, nonspillable and maintenance-free.
Do 21700 batteries fit 18650?

Can you use lithium batteries in flashlights?
As the battery is used and ages, internal resistance increases, and it takes progressively less of a load for the voltage sag to occur. In practice, though, after a short time, the lithium AA battery voltage will sag to 1.6 volts, which is safe enough for most flashlights and other devices.
Are rechargeable batteries good for flashlights?
Rechargeable lithium batteries have a higher power capacity compared to AA batteries. This process makes them more capable of delivering the required output for high-drain devices like flashlights like rechargeable LED flashlights.
