# ICR14500 battery

**What replaces a ICR14500: 14500 Li-ion, ICR14500, INR14500**

3.6 V lithium-ion (rechargeable), 14 × 50 mm (diameter × height)

The ICR14500 is a rechargeable 3.6 V lithium-ion (rechargeable) cylindrical. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** ICR14500
- **Nominal voltage:** 3.6 V
- **Chemistry:** Lithium-ion (rechargeable)
- **Size:** 14 × 50 mm (diameter × height)
- **Typical capacity:** 800 mAh
- **Rechargeable:** Yes

## Codes that mean the same battery

*Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.*

| Code | Fits? |
| --- | --- |
| 14500 Li-ion | Yes — same cell |
| ICR14500 | Yes — same cell |
| INR14500 | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| AA / LR6 | The same shape and size as an AA, and more than twice the voltage. This is the single most consequential size collision in consumer batteries: a 14500 fitted to a device expecting 1.5 V applies 4.2 V straight off the charger. Only fit one where the manufacturer explicitly lists 14500 support. |
| NiMH AA | Also rechargeable and the same size, but 1.2 V. NiMH is the safe AA substitute; 14500 is not. |

## Where it turns up

- Torches that explicitly support 3.7 V AA-size cells
- Vape devices and small e-cigs
- Some RC transmitters and models
- DIY electronics projects

> Genuine capacity runs 700–1000 mAh — well under an alkaline AA in milliamp-hours, though at more than twice the voltage the energy is comparable.

## Common questions

### What is equivalent to a ICR14500?

14500 Li-ion, ICR14500, INR14500 — all the same 3.6 V cell under different manufacturer codes.

### Can I use a AA / LR6 instead of a ICR14500?

The same shape and size as an AA, and more than twice the voltage. This is the single most consequential size collision in consumer batteries: a 14500 fitted to a device expecting 1.5 V applies 4.2 V straight off the charger. Only fit one where the manufacturer explicitly lists 14500 support.

### Is the ICR14500 rechargeable?

Yes. Use a charger made for its chemistry and never substitute a primary cell of the same size.
