LR44 / SR44
Compare specifications and explicit assessments. The direction is required battery → candidate replacement.
Directed assessment
Required LR44 → candidate SR44
Conditional only: chemistry and voltage differ. Check the device instructions and every condition below.
SR44 has 1.55 V instead of 1.5 V. The device must accept the chemistry, voltage and load profile.
No automatic replacement recommendation. Device compatibility has not been verified. Dimensions alone do not prove that a battery fits or works.
Replacement limits
- Use a holder for the correct bare-cell size.
- Observe the correct polarity.
- The device manufacturer must accept the candidate chemistry and voltage.
- Match the required load profile, including W/SW.
- Do not use these primary cells in a charging circuit.

The type status describes documentary checks of core specifications, not every fact or suitability for a device.
| Technical specifications | LR44 | SR44 |
|---|---|---|
| ChemistryDifferent | Alkaline zinc / manganese dioxide | Silver oxide / zinc |
| Nominal voltageDifferent | 1.5 V | 1.55 V |
| Reference dimensionsSame | Ø 11.6 × 5.4 mm | Ø 11.6 × 5.4 mm |
| RechargeableSame | No | No |
Rechargeable does not mean interchangeable. Charging circuitry, terminal shape and device compatibility have not been verified. Never charge a primary cell.
