14500 Battery Australia
The 14500 is a rechargeable lithium-ion cell that shares the same physical size as an AA battery (14mm by 50mm) but runs at 3.7V rather than 1.5V. It is used in compact torches and devices specifically designed for 14500 cells.
Important: a 14500 is not a drop-in replacement for an AA unless your device explicitly supports the higher voltage.

Frequently Asked Questions
Can I use a 14500 instead of an AA battery?
Only if your device is rated for 3.7V cells. A standard AA is 1.5V, so putting a 3.7V 14500 into an AA device not designed for it can damage the device. Always check compatibility first.
