# LR20 battery

**What replaces a LR20: LR20, 13A, MN1300, E95, AM1, Mono**

1.5 V alkaline, 34.2 × 61.5 mm (diameter × height)

The LR20 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:** LR20
- **ANSI / NEDA:** 13A
- **Nominal voltage:** 1.5 V
- **Chemistry:** Alkaline
- **Size:** 34.2 × 61.5 mm (diameter × height)
- **Typical capacity:** 12000 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? |
| --- | --- |
| LR20 | Yes — same cell |
| 13A | Yes — same cell |
| MN1300 | Yes — same cell |
| E95 | Yes — same cell |
| AM1 | Yes — same cell |
| Mono | Yes — same cell |
| UM-1 | Yes — same cell |
| Type 13 | Yes — same cell |
| R20 (zinc-carbon size) | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| C / LR14 | Smaller in every dimension. An adapter makes a C fit a D holder but halves the runtime. |

> The LR20 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

- Large torches and emergency lanterns
- Portable stereos and megaphones
- Motorised ride-on toys
- Some medical and laboratory equipment

> Roughly 12,000–18,000 mAh at a low drain, the highest of any common household cell. Many cheap D cells are a C cell in a D shell with a spacer; weight is a fair proxy for whether you got a real one.

## Common questions

### What is equivalent to a LR20?

LR20, 13A, MN1300, E95, AM1, Mono, UM-1, Type 13, R20 (zinc-carbon size) — all the same 1.5 V cell under different manufacturer codes.

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

Smaller in every dimension. An adapter makes a C fit a D holder but halves the runtime.

### Is the LR20 rechargeable?

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