# LR14 battery

**What replaces a LR14: LR14, 14A, MN1400, E93, AM2, Baby**

1.5 V alkaline, 26.2 × 50 mm (diameter × height)

The LR14 is a single-use 1.5 V alkaline cylindrical. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** LR14
- **ANSI / NEDA:** 14A
- **Nominal voltage:** 1.5 V
- **Chemistry:** Alkaline
- **Size:** 26.2 × 50 mm (diameter × height)
- **Typical capacity:** 7500 mAh
- **Rechargeable:** No — never charge it

## Codes that mean the same battery

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

| Code | Fits? |
| --- | --- |
| LR14 | Yes — same cell |
| 14A | Yes — same cell |
| MN1400 | Yes — same cell |
| E93 | Yes — same cell |
| AM2 | Yes — same cell |
| Baby | Yes — same cell |
| UM-2 | Yes — same cell |
| Type 14 | Yes — same cell |
| R14 (zinc-carbon size) | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| D / LR20 | Much larger at 34.2 × 61.5 mm. The plastic C-to-D adapters sold for the purpose work mechanically but give you C capacity in a D socket, which is roughly half the runtime. |

> The LR14 is a primary cell and must never be put in a charger. Charging a sealed primary battery builds gas pressure inside a can with no vent designed for it, which is how they rupture or catch fire. Rechargeable look-alikes exist for several sizes and carry different codes — check the code, not the shape.

## Where it turns up

- Larger torches and camping lanterns
- Portable radios and boomboxes
- Musical instrument amplifiers and effects
- Some motorised toys

> Around 7000–8000 mAh at a low drain. Same 1.5 V as an AA; the extra size buys runtime and current, not voltage.

## Common questions

### What is equivalent to a LR14?

LR14, 14A, MN1400, E93, AM2, Baby, UM-2, Type 14, R14 (zinc-carbon size) — all the same 1.5 V cell under different manufacturer codes.

### Can I use a D / LR20 instead of a LR14?

Much larger at 34.2 × 61.5 mm. The plastic C-to-D adapters sold for the purpose work mechanically but give you C capacity in a D socket, which is roughly half the runtime.

### Is the LR14 rechargeable?

No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
