# LR8D425 battery

**What replaces a LR8D425: LR8D425, LR61, 25A, MN2500, E96, MX2500**

1.5 V alkaline, 8.3 × 42.5 mm (diameter × height)

The LR8D425 is a single-use 1.5 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:** LR8D425
- **ANSI / NEDA:** 25A
- **Nominal voltage:** 1.5 V
- **Chemistry:** Alkaline
- **Size:** 8.3 × 42.5 mm (diameter × height)
- **Typical capacity:** 600 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? |
| --- | --- |
| LR8D425 | Yes — same cell |
| LR61 | Yes — same cell |
| 25A | Yes — same cell |
| MN2500 | Yes — same cell |
| E96 | Yes — same cell |
| MX2500 | Yes — same cell |
| AM6 | Yes — same cell |
| LR8 | Yes — same cell |
| Type 25 | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| AAA | Two millimetres wider and two longer. AAAA is a distinct size, not a smaller AAA, and one is not a substitute for the other. |
| N / LR1 | Shorter and fatter at 12 × 30.2 mm. Both are uncommon sizes, which is exactly why they get confused. |

> The LR8D425 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

- Surface Pen and Microsoft active styluses
- Some Wacom and HP stylus pens
- Slim laser pointers
- Small medical penlights

> Six of these are what is inside a 9 V battery — which is why prising one open is a known way to get an AAAA in an emergency. Do it with a proper 6LR61 alkaline, not a lithium or a rechargeable, and expect to void every warranty involved.

## Common questions

### What is equivalent to a LR8D425?

LR8D425, LR61, 25A, MN2500, E96, MX2500, AM6, LR8, Type 25 — all the same 1.5 V cell under different manufacturer codes.

### Can I use a AAA instead of a LR8D425?

Two millimetres wider and two longer. AAAA is a distinct size, not a smaller AAA, and one is not a substitute for the other.

### Is the LR8D425 rechargeable?

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