Equivalent batteries
These codes describe the same physical cell as the 14500.
Can I replace 14500 with…
Cells that fit the same space but differ in chemistry or voltage.
Alkaline, 14.5 × 50.5 mm. Different footprint — check the compartment before buying.
Runs at 1.5 V against the 14500’s 3.6 V. That 2.1 V gap can damage a device built for the 14500.
The AA is single-use and must never be recharged.
Li-ion, 18 × 65 mm. Different footprint — check the compartment before buying.
Check before you swap. Batteries with similar dimensions are not always interchangeable with the 14500. Always verify voltage, chemistry and the requirements printed in your device manual before fitting a replacement.
14500 questions
What batteries are equivalent to the 14500?
The 14500 is sold as ICR14500. All of these describe the same 14 × 50 mm li-ion cell at 3.6 V.
Can I use a AA instead of a 14500?
In many low-drain devices, yes — the sizes match. Check the voltage and chemistry against your device's requirement first, because a small voltage difference can matter in calibrated equipment.
How long does a 14500 last?
A 14500 holds a typical 700–1000 mAh. Real runtime depends entirely on how much current your device draws and whether it is used continuously.
Is the 14500 rechargeable?
Yes, the 14500 is a rechargeable cell and must be charged in a charger designed for its chemistry.
