Write the first reviewThe Varta V28PX / 4SR44 silver oxide battery (6.2V) is a high-quality, non-rechargeable specialist battery primarily used in analogue cameras (such as the Mamiya 645), electronic measuring equipment, car keys and medical devices.Thanks to its silver oxide technology, this battery delivers a very stable voltage throughout its entire lifespan. This is essential for accurate light metering in classic cameras.
Key specifications
Voltage: 6.2 Volts
System: Silver oxide / Zinc (Zn/Ag2O).
Dimensions: 13 mm diameter and 25.2 mm height.
Weight: 11.1 grams.
Shelf life: Very low self-discharge, with a guaranteed storage life of up to 3.5 to 5 years.
Silver oxide cells perform excellently in fluctuating temperatures (between -10 °C and +65 °C) and retain their voltage better than cheaper alkaline variants (such as the 4LR44). This makes the Varta V28PX ideal for older-generation analogue cameras and SLR cameras.
