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.

Codes that mean the same battery
| 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.
