VARTA 357101111 – silver oxide button cell for small devices
VARTA 357101111 is a mercury-free primary silver oxide button cell battery, meaning it is a small primary battery for equipment that requires a stable and compact power supply. It delivers 1.55 V and is specified for use in watches, medical equipment, cameras, and electronic devices, among other things.
What particularly characterizes a silver oxide button cell like the VARTA 357101111 is its steady voltage and relatively high capacity in a small format. The capacity is typically 145 mAh, measured with a 5.6 kΩ load at 20 °C down to 1.2 V. For the user, this means the battery is well-suited for applications where space is limited, but where stable operation over time is still expected.
Dimensions and weight are also relevant in practice. The battery has a diameter of 11.6 mm, a height of 5.40 mm, and weighs approx. 2.33 g. This makes it easy to match with the correct battery compartment in small instruments and precision equipment.
