Varta Silver Oxide Button Cell - Silver - 00395101401

This battery is ideal for small electronic devices such as quartz watches, calculators, car key fobs, remote controls, digital thermometers, and other microelectronic applications that require a 1.55V power source.

The lifespan varies greatly depending on the device's power consumption. However, due to its high capacity (42 mAh) and low self-discharge, it offers extended operational life, often lasting several years in typical watch applications.

No, the Varta V395/SR57 is a single-use (primary) silver oxide battery and is not designed to be recharged. Attempting to recharge it can be dangerous.

These are industry designations for the battery's size and chemistry. SR typically denotes Silver Oxide, and the numbers (e.g., 57, 395) refer to its specific dimensions (diameter and height) and internal configuration.

Store them in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures. This helps maintain their charge due to the low self-discharge rate.

Silver oxide batteries like the V395 have a very low self-discharge rate, typically offering a shelf life of several years (often 5+ years) when stored properly.

Consult the user manual for your specific electronic device. It will usually indicate the correct battery type, size, and provide instructions for replacement.

Ensure the battery is inserted with the correct polarity (+ and -). Check that the battery terminals and device contacts are clean. Verify that the compartment cover is securely closed.

The battery may be depleted or not making proper contact. Re-seat the battery, ensuring a firm connection. If the issue persists, try a new battery as the current one may be expired or faulty.

Use a proper tool designed for opening battery compartments, or a small flathead screwdriver used carefully. Avoid excessive force, which can damage the device.
