Description

The Duracell CR1620 is a 3V lithium coin cell battery measuring 16mm diameter by 2.0mm thickness, designed for car key fobs, watches, calculators, fitness trackers and other small electronics requiring a CR1620 cell. The lithium chemistry provides a stable 3V output throughout the battery's service life, avoiding the voltage drop-off that occurs with cheaper alkaline alternatives.

Supplied as a single battery in child-resistant blister packaging, the CR1620 suits users replacing a single cell in a watch or key fob rather than bulk-buying cells for multiple devices. The packaging meets child safety standards, requiring scissors to open rather than simple hand pressure. Most car key fobs for vehicles manufactured from 2010 onwards use either a CR2032 or CR1620 cell — check your existing battery before ordering.

Duracell rates the CR1620 for up to 10 years of shelf life when stored at room temperature in the sealed blister pack, making it viable as a spare battery kept in a desk drawer or glovebox. The lithium cell tolerates temperature extremes better than alkaline cells, remaining functional in cold weather where car key fobs are often used outdoors in winter. At 0.01kg, the single-cell blister adds minimal weight to a spares kit or toolbox.

Frequently Asked

What devices use a CR1620 battery?

CR1620 cells are commonly found in car key fobs, wristwatches, small calculators, fitness trackers, glucose monitors and LED keychain lights. Check the existing battery in your device before ordering — CR1620 is easily confused with the thicker CR2016 or larger CR2032.

How long does a CR1620 last?

Service life depends on the device's power draw. In a car key fob with moderate use (10-20 button presses per day), a CR1620 typically lasts 2-4 years. In a watch with no backlight, 3-5 years is common. High-drain devices like fitness trackers drain the cell faster.

Can I use a CR1616 or CR2016 instead?

CR1616 is thinner (1.6mm vs 2.0mm) and may rattle in a CR1620 battery compartment, causing poor contact. CR2016 is thicker and will not fit. Always match the exact cell size marked on the original battery.

What is the shelf life?

Duracell rates the CR1620 for up to 10 years of shelf life when stored in the sealed blister pack at room temperature. Once opened, use within 12 months for best performance.
