# 8LR732 battery

**What replaces a 8LR732: 27A, 8LR732, MN27, V27GA, L828, GP27A**

12 V alkaline, 8 × 28.2 mm (diameter × height)

The 8LR732 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:** 8LR732
- **Nominal voltage:** 12 V
- **Chemistry:** Alkaline
- **Size:** 8 × 28.2 mm (diameter × height)
- **Typical capacity:** 22 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? |
| --- | --- |
| 27A | Yes — same cell |
| 8LR732 | Yes — same cell |
| MN27 | Yes — same cell |
| V27GA | Yes — same cell |
| L828 | Yes — same cell |
| GP27A | Yes — same cell |
| A27BP | Yes — same cell |
| G27A | Yes — same cell |
| EL812 | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| A23 / 8LR932 | The same 12 V and nearly the same length, but 2.3 mm wider and with more than twice the capacity. An A27 in an A23 holder makes poor contact; an A23 will not enter an A27 holder. |

> The 8LR732 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

- Slim car alarm and keyless entry remotes
- Gate and barrier remotes
- Some medical alert buttons
- Wireless doorbell transmitters

## Common questions

### What is equivalent to a 8LR732?

27A, 8LR732, MN27, V27GA, L828, GP27A, A27BP, G27A, EL812 — all the same 12 V cell under different manufacturer codes.

### Can I use a A23 / 8LR932 instead of a 8LR732?

The same 12 V and nearly the same length, but 2.3 mm wider and with more than twice the capacity. An A27 in an A23 holder makes poor contact; an A23 will not enter an A27 holder.

### Is the 8LR732 rechargeable?

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