What are 14500 Batteries?
The 14500 battery is a cylindrical li-ion cell classified by its roughly 49.2mm length and 13.5mm diameter, and is the rechargeable version of an AA battery. They usually have a 3.6V or 3.7V voltage, button-top terminal, and most use a LiCoO2 (lithium carbon-oxide) ICR chemistry. While some come with built-in USB charging ports, most 14500 batteries are rechargeable in li-ion smart chargers. 14500 cells are often used in flashlights, and are an economic and environmentally friendly alternative to disposable AA batteries in compatible devices.

Rechargeable batteries and chargers provide a reusable alternative to disposable batteries. These batteries (also called secondary cells) can be replenished for multiple uses by a compatible charger to eliminate the need for constant replacement. They're ideal for powering high-drain equipment such as keyless entry systems, digital audio devices, digital cameras, GPS, and video game controllers. They are sized according to the same ANSI/IEC standards as disposable batteries, so they can be used as direct replacements.

Is a 14500 battery the same as an AA battery?
No. While 14500 and AA batteries share the same general dimensions, they have distinctly different voltages due to their chemistries. 14500 cells may also have built in PTC or other protection systems, which can slightly increase their overall length.

Primary AA batteries usually that use alkaline, lithium, or zinc-chloride chemistries have a 1.5V nominal voltage, while rechargeable AAs using NiMH or NiCd chemistries have a 1.2V nominal voltage.

14500 batteries use lithium-ion chemistry and have a 3.6/3.7V nominal voltage, and are rechargeable. Due to their higher voltage, they are not always a suitable replacement for AAs. Check your device's user manual for battery compatibility.
