FAQs
What does 'SR63' or 'SR521' mean?
These are industry standard designations for button cell batteries, indicating their size (diameter and height) and chemistry (Silver-Oxide).
Can I recharge the Varta V379 battery?
No, the Varta V379 is a single-use (primary) battery and is not designed to be recharged. Attempting to recharge it can be dangerous and damage the device.
How long will this battery last?
The lifespan depends on the device's power consumption. For a typical watch, it can last 1-3 years. For calculators or other devices used intermittently, it may last longer.
What is the difference between 1.55V and other button cell voltages?
1.55V is standard for silver-oxide button cells. Other button cells may have different voltages (e.g., 1.5V alkaline or 3V lithium) and are not interchangeable.
How should I dispose of used Varta V379 batteries?
Silver-oxide batteries should be disposed of responsibly. Check with your local waste management authority for battery recycling or disposal guidelines. Do not dispose of them in regular household trash.
What does 'mAh' mean?
mAh stands for milliampere-hour, which is a measure of electric charge capacity. A higher mAh generally indicates a battery can supply current for a longer time.
Troubleshooting
Device does not power on after battery replacement
Ensure the battery is inserted with the correct polarity (+/-). Check that the battery contacts in the device are clean and making proper contact. Try a different Varta V379 battery if available.
Device is not functioning correctly (e.g., intermittent display, slow response)
The battery may be low or faulty. Replace with a fresh Varta V379 battery. Ensure the battery is fully seated and the device's contacts are clean.
Battery appears to be leaking
Immediately remove the battery from the device using appropriate tools (gloves recommended). Clean any residue from the battery compartment with a dry cloth or eraser. Dispose of the leaking battery properly and replace it.
Pros and Cons

Setup, Compatibility & Care
Setup:
- Ensure the device requiring the battery is powered off.
- Carefully open the device compartment, typically on the back of watches or under a small cover on other electronics.
- Note the orientation of the old battery (positive '+' and negative '-' terminals).
- Gently remove the old battery. Use a non-metallic tool if necessary to avoid short circuits.
- Insert the new Varta V379 battery, ensuring it matches the orientation of the old one.
- Close the device compartment securely.
- Power on the device and verify it is functioning correctly.
Compatibility:
- This battery is primarily compatible with devices specifying the SR63 or SR521 battery size.
- Always check your device's manual or the existing battery for the correct model number and voltage.
- It is designed for devices that require a 1.55V silver-oxide button cell.
Care:
- Handle batteries with clean, dry hands or non-metallic tweezers.
- Avoid exposing batteries to extreme temperatures or moisture.
- Do not attempt to recharge, disassemble, or expose batteries to fire, as this can cause leakage or explosion.
- Store unused batteries in their original packaging in a cool, dry place.
