Ensure your vintage camera performs at its best with the Varta 4SR44 6V Silver Oxide Battery.
This high-quality, long-lasting battery delivers consistent voltage, making it the perfect choice for light meter accuracy and electronic functionality in classic analogue cameras.
✅ Also Known As This battery is compatible with many part numbers and cross-references, including:
PX28S, PX28A, 544, V28PX, S28PX, A544, 4SR44W, K28A, RPX28
⚠️ Important Notes:
- 4SR44 is a 6V Silver Oxide battery, offering better voltage stability than alkaline equivalents.
- Do not confuse it with 4LR44, which is an alkaline version with a slightly different discharge curve—suitable for some devices but less accurate in cameras that depend on consistent voltage (e.g., for metering).
Use 4SR44 (silver oxide) over 4LR44 when powering:
- Cameras with light meters that are voltage-sensitive
- Devices requiring long-lasting, consistent output
