The Varta CR 1620 is a high-performance 3V lithium button cell battery designed for small electronic devices such as watches, key fobs, and medical sensors. It is ideal for users needing a stable, long-lasting power source that excels in diverse thermal environments; however, it is a single-use battery and cannot be recharged once depleted.

No, this is a primary lithium-manganese dioxide battery and is designed for single-use only. Attempting to recharge it can be dangerous.
No, CR1620 and CR2032 batteries have different diameters and thicknesses. Always use the size specified by your device manufacturer.
Avoid skin contact. Use gloves to remove the battery, clean the device contacts with a cotton swab and a tiny amount of vinegar or lemon juice, and dispose of the battery according to local hazardous waste regulations.
Do not throw it in regular household trash. Take the battery to a designated battery recycling collection point to ensure safe processing.
Button batteries pose a severe risk of internal chemical burns or choking if swallowed; always keep them out of reach of infants and small children.
Verify the battery is inserted with the correct polarity (+ facing up as marked) and that the battery contacts are clean.
Check the battery contacts for oxidation and clean them gently with a dry cloth; if the issue persists, test the voltage with a multimeter to ensure the cell is not depleted.
When installing the Varta CR 1620, ensure the device battery compartment is clean and free of moisture or corrosion. Use non-metallic tweezers or dry, clean fingers to handle the battery to prevent finger oils from affecting electrical conductivity. Always ensure the positive (+) side faces the designated marking in your device. If a device will not be used for an extended period, it is recommended to remove the battery to prevent potential leakage. Store unused batteries in a cool, dry place and keep them in their original blister packaging until use to prevent accidental short-circuiting against other metal objects.
