# 8LR932 battery

**What replaces a 8LR932: 23A, 8LR932, MN21, V23GA, LRV08, L1028**

12 V alkaline, 10.3 × 28.5 mm (diameter × height)

The 8LR932 is a single-use 12 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:** 8LR932
- **ANSI / NEDA:** 1181A
- **Nominal voltage:** 12 V
- **Chemistry:** Alkaline
- **Size:** 10.3 × 28.5 mm (diameter × height)
- **Typical capacity:** 55 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? |
| --- | --- |
| 23A | Yes — same cell |
| 8LR932 | Yes — same cell |
| MN21 | Yes — same cell |
| V23GA | Yes — same cell |
| LRV08 | Yes — same cell |
| L1028 | Yes — same cell |
| GP23A | Yes — same cell |
| 1181A | Yes — same cell |
| A23S | Yes — same cell |
| 8LR23 | Yes — same cell |
| E23A | Yes — same cell |
| K23A | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| A27 / 8LR732 | Also 12 V, but 8.0 × 28.2 mm rather than 10.3 × 28.5 — narrower, and with under half the capacity. It rattles in an A23 holder and dies quickly. |
| N / LR1 | A similar-sized cylinder at 1.5 V. Fitting an A23 where an N belongs applies eight times the voltage to the circuit. |

> The 8LR932 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

- Garage door and gate remotes
- Car alarm and keyless entry fobs
- Wireless doorbells
- Some camera remote releases

> Eight tiny LR932 alkaline cells stacked in a tube. That construction is why it delivers 12 V from a AAA-sized package and also why it can only supply about 15 mA — plenty for a radio transmitter burst, nowhere near enough to drive a motor or a lamp.

## Common questions

### What is equivalent to a 8LR932?

23A, 8LR932, MN21, V23GA, LRV08, L1028, GP23A, 1181A, A23S, 8LR23, E23A, K23A — all the same 12 V cell under different manufacturer codes.

### Can I use a A27 / 8LR732 instead of a 8LR932?

Also 12 V, but 8.0 × 28.2 mm rather than 10.3 × 28.5 — narrower, and with under half the capacity. It rattles in an A23 holder and dies quickly.

### Is the 8LR932 rechargeable?

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