Yashica Electro 35 battery
1 × 5.6V mercury (legacy) cell
The Yashica Electro 35 (G / GS / GSN / GTN variants) originally took a ~5.6V mercury PX32 / HM-N / E164. Modern alkaline A32PX / PX32A are the usual replacements. Do not treat this as a Canon AE-1 4LR44 / PX28 answer — adapter and battery-check behaviour differ.
How to replace it
| Compartment | Battery chamber in the camera body |
|---|---|
| How to open | Open the battery cover; insert a PX32-class modern alkaline (A32PX / PX32A) or a documented adapter path. Match polarity. |
| Orientation | Follow polarity marks |
| Low battery indicator | Battery check lamp / over-under exposure lamps behave incorrectly when the cell is weak |
| Notes | Specialist sources caution that some PX28A + adapter setups can fail the battery check under load — prefer a documented A32PX / PX32A path. |
| Access | Tool-free |
Important
- Original power source was a ~5.6V mercury PX32 / HM-N / E164 — obsolete.
- Modern alkaline A32PX / PX32A (~6V) are the usual replacements for Electro 35 variants (G / GS / GSN / GTN — confirm your body).
- Do not flatten this to a Canon AE-1 4LR44 / PX28 answer without caveats — form factor and battery-check behaviour differ.
- Adapter + PX28A paths are debated; some fail the battery check under load.
- Keep cells away from children.

New battery but still not working?
A fresh 1 × PX32 should restore Yashica Electro 35 if the battery was the problem. Work through the checks below before replacing the device.
- Check orientation
Confirm the cell is seated correctly: Follow polarity marks
- Check the battery type
This device needs 1 × PX32 (mercury_oxide_legacy). Rechargeable cells are not supported for this device. Same size does not always mean the same battery.
- Check known model-specific issues
Original power source was a ~5.6V mercury PX32 / HM-N / E164 — obsolete. Modern alkaline A32PX / PX32A (~6V) are the usual replacements for Electro 35 variants (G / GS / GSN / GTN — confirm your body).

- Confirm the battery itself
Try a known-good fresh cell of the exact code listed above.
- Still not responding?
If a correct, fresh battery installed properly does not restore the device, the fault may be elsewhere — the device may need service or replacement.
