Why this verdict
- The physical envelope matches.
- Nominal voltage differs: 1.4 V versus 1.5 V.
- Chemistry also changes from Zinc air to Alkaline manganese dioxide.
What to verify in the device
Check the original compartment label, the current manual, polarity, terminal style and whether the device explicitly permits a chemistry or rechargeable alternative.
