# PR70 battery

**What replaces a PR70: ZA10, A10, AC10, DA10, P10, 10A**

1.4 V zinc-air, 5.8 × 3.6 mm (diameter × height)

The PR70 is a single-use 1.4 V zinc-air button cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** PR70
- **ANSI / NEDA:** 7005ZD
- **Nominal voltage:** 1.4 V
- **Chemistry:** Zinc-air
- **Size:** 5.8 × 3.6 mm (diameter × height)
- **Typical capacity:** 98 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? |
| --- | --- |
| ZA10 | Yes — same cell |
| A10 | Yes — same cell |
| AC10 | Yes — same cell |
| DA10 | Yes — same cell |
| P10 | Yes — same cell |
| 10A | Yes — same cell |
| S10 | Yes — same cell |
| V10 | Yes — same cell |
| 7005ZD | Yes — same cell |
| PR536 | Yes — same cell |
| PR70 | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| Size 312 / PR41 | The next size up: 7.9 mm across rather than 5.8. Brown tab, not yellow. It will not enter a size 10 door. |

> The PR70 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

- In-the-canal and invisible-in-canal hearing aids
- Completely-in-canal instruments
- The smallest receiver-in-canal aids
- Some miniature medical monitors

> Yellow tab. Once the tab is off the cell is live for good — expect three to seven days of use, and give it a full minute of air before closing the battery door or the first reading of voltage will be low.

## Common questions

### What is equivalent to a PR70?

ZA10, A10, AC10, DA10, P10, 10A, S10, V10, 7005ZD, PR536, PR70 — all the same 1.4 V cell under different manufacturer codes.

### Can I use a Size 312 / PR41 instead of a PR70?

The next size up: 7.9 mm across rather than 5.8. Brown tab, not yellow. It will not enter a size 10 door.

### Is the PR70 rechargeable?

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