Renata CR1620 3V Lithium Coin Cell 10-Pack

Reliable Power for Small Devices

This ten-pack supplies CR1620 lithium coin cells rated at three volts for watches, calculators, medical devices and other compact electronics. Renata chemistry delivers steady output across the full discharge curve so each unit performs consistently from first use to last. The pack suits households, workshops and service benches that need a ready reserve of fresh cells. Buyers who require rechargeable formats or larger cylindrical sizes will not be served by this product.

Sustained Output Under Continuous Load

Lithium chemistry maintains a stable voltage plateau during prolonged draw, avoiding the voltage sag common in alkaline alternatives when a device runs for hours or days. The cells tolerate a wide temperature range without significant capacity loss, making them dependable in outdoor sensors or automotive key fobs exposed to seasonal extremes. Each battery is engineered for high energy density and continuous voltage supply throughout its service life. No internal protection circuit or smart monitoring feature is included.

Limits of the CR1620 Form Factor

The 16 mm diameter and 2 mm thickness fix the physical envelope, so any device compartment must match these dimensions exactly for proper contact. Capacity is bounded by the coin-cell geometry; applications demanding higher milliampere-hour ratings must select a larger cell format. Equivalent designations such as DL1620, BR1620, ECR1620, KCR1620, LM1620, 5009LC and L08 refer to the same mechanical and electrical specification. Shelf life reaches up to ten years when stored at room temperature.
