# LR754 battery

**What replaces a LR754: 193, AG5, LR48, L754, V5GA, GP193**

1.5 V alkaline, 7.9 × 5.4 mm (diameter × height)

The LR754 is a single-use 1.5 V alkaline button cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** LR754
- **Nominal voltage:** 1.5 V
- **Chemistry:** Alkaline
- **Size:** 7.9 × 5.4 mm (diameter × height)
- **Typical capacity:** 53 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? |
| --- | --- |
| 193 | Yes — same cell |
| AG5 | Yes — same cell |
| LR48 | Yes — same cell |
| L754 | Yes — same cell |
| V5GA | Yes — same cell |
| GP193 | Yes — same cell |
| G5A | Yes — same cell |
| 309A | Yes — same cell |
| 393A | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| SR754 / 393 | Silver oxide in the same can, 1.55 V flat, half again the capacity. |
| PR48 / size 13 hearing aid | Identical 7.9 × 5.4 mm dimensions, but zinc-air at 1.4 V with vent holes that must stay open. Never a substitute either way. |

> The LR754 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

- Small torches and penlights
- Toys and novelty lights
- Older calculators
- Electronic locks

## Common questions

### What is equivalent to a LR754?

193, AG5, LR48, L754, V5GA, GP193, G5A, 309A, 393A — all the same 1.5 V cell under different manufacturer codes.

### Can I use a SR754 / 393 instead of a LR754?

Silver oxide in the same can, 1.55 V flat, half again the capacity.

### Is the LR754 rechargeable?

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