What replaces a LR1
LR1, 910A, E90, MN9100, LR01, AM5
1.5 V alkaline, 12 × 30.2 mm (diameter × height)

Codes that mean the same battery
| Code | Fits? |
|---|---|
| LR1 | Yes — same cell |
| 910A | Yes — same cell |
| E90 | Yes — same cell |
| MN9100 | Yes — same cell |
| LR01 | Yes — same cell |
| AM5 | Yes — same cell |
| UM-5 | Yes — same cell |
| Lady | Yes — same cell |
| R1 (zinc-carbon size) | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| AAAA | Narrower and longer at 8.3 × 42.5 mm. Both are odd sizes and both turn up in styluses and remotes, which is how the mix-up happens. |
| A23 | A similar-looking 10.3 × 28.5 mm cylinder, but 12 V. Fitting one where an N belongs applies eight times the voltage. |
The LR1 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
- Bluetooth and glucose meter accessories
- Some door chimes and garage remotes
- Medical penlights
- Older camera bodies and flash units
Common questions
- What is equivalent to a LR1?
- LR1, 910A, E90, MN9100, LR01, AM5, UM-5, Lady, R1 (zinc-carbon size) — all the same 1.5 V cell under different manufacturer codes.
- Can I use a AAAA instead of a LR1?
- Narrower and longer at 8.3 × 42.5 mm. Both are odd sizes and both turn up in styluses and remotes, which is how the mix-up happens.
- Is the LR1 rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
