Coin cell for low-drain devices

The Duracell DL1620BPK is a single 3 V lithium coin cell sized to the 1620 form factor. It ships new in a 1-pack and is designed for equipment that draws very little current over long periods. Typical uses include key fobs, medical monitors and small security sensors.

Suits intermittent low-power needs

This cell suits owners replacing a single coin battery in a device that specifies the 1620 size and 3 V nominal voltage. It is not intended for high-drain applications such as LED torches or motorised toys, and buyers who need multiple spares should look for a larger pack.

Drops into existing 1620 holders

The battery fits directly into any spring or clip holder built for the 1620 footprint, requiring no soldering or adapter. Its alkaline chemistry provides a stable voltage curve that keeps low-power circuits running until the cell is depleted, freeing the user from frequent replacements.

Questions about this item

What device takes a 1620-size 3 V coin cell so this pack will power it?

Any device that specifies a CR1620 or DL1620 3 V lithium coin cell — car key fobs, medical monitors, small remotes and similar electronics.

Will this 3 V alkaline coin cell work in older gear that originally used a 1620 silver-oxide cell?

No — silver-oxide cells operate at a lower voltage, so this 3 V cell can damage equipment designed for them.

How can I confirm the cell is delivering the rated 3 V after installation?

Measure the voltage across the terminals with a multimeter; a fresh cell should read close to 3 V DC.
