Codes that mean the same battery
| 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.
