Battery Bosch CR1620B1/00 lithium coin cell — 1 piece

Lithium coin cell Bosch CR1620B1/00 supplied as a single piece in blister packaging. This 3V CR1620 size cell is intended for low-drain electronic devices that require stable voltage and long shelf life. The battery is suitable for devices where compact size and reliable long-term performance matter, such as watches, key fobs, calculators, small medical instruments and memory backup circuits.

Advantages

The Bosch CR1620B1/00 offers stable 3V output throughout most of its discharge curve and long shelf life typical of lithium chemistry. Its compact coin-cell form factor provides a reliable power source in small housings while blister packaging protects the cell from mechanical contact and contamination before use. The battery is designed for predictable performance in low-current applications and for straightforward replacement of other CR1620 cells.

Suitable for

• Wristwatches and timepieces
• Remote key fobs and car remotes
• Calculators and small electronic toys
• Memory backup modules and CMOS backup
• Small medical devices with low current draw (e.g., glucose meters, hearing-aid accessories)

Key specifications

• Nominal voltage: 3 V
• Cell type: Lithium coin cell (CR1620 size)
• Quantity: 1 piece in blister pack
• Designed for low-drain applications and memory backup

How to use

Open the blister packaging and remove the battery using dry hands or non-conductive tweezers. Observe correct polarity when inserting the CR1620 into the device: the positive (+) side faces outward as indicated by most device markings. Ensure the battery contacts and the device compartment are clean and dry before installation. Dispose of used lithium coin cells according to local regulations or recycle at an appropriate collection point.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and heat sources. Do not expose to fire or short circuit the terminals. Replace the battery at the first sign of reduced device performance and avoid mixing new and old batteries in multi-cell devices.
