Why this verdict
- The physical envelope matches.
- Nominal voltage is close.
- Chemistry and discharge behavior differ.
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.
