When do you need a silver oxide battery?
Silver oxide batteries such as the V390 are specially designed for small electronic devices that require a stable voltage of 1.55V. You use this battery in watches, calculators, hearing aids, small toys and other compact electronics. Thanks to their reliable energy supply, they are ideal for devices that need to function for a long time.

Why choose this V390 variant?
This battery measures 11.6 mm in diameter and 3.05 mm in height, which corresponds to the SR54 size. With a capacity of 59 mAh, it provides sufficient energy for most applications in this size. You choose this variant when your device specifically calls for these dimensions or when one of the reference codes matches.

Reliable silver oxide technology
Silver oxide batteries offer a more constant voltage than ordinary alkaline button cells, which is especially important for precision devices such as watches. The voltage remains stable at 1.55V for almost the entire life of the battery, so your device keeps working optimally until the battery is nearly empty.

Check your device for compatibility
Look in your device, manual or on the old battery for one of these codes: SR1130, SR1130SW, 389/390, 390, or 389/390/398. The VARTA reference 00390 101 111 can also help you identify it. The battery comes packaged in a blister pack, which provides protection during storage and transport.
