Description

The Energizer CR1616 is a 3V lithium coin cell battery measuring 16mm in diameter and 1.6mm thick, designed for compact electronics including car key fobs, glucose monitors, fitness trackers, small LED lights and calculator watches. The lithium manganese dioxide chemistry provides stable voltage output across the battery's discharge curve, maintaining consistent performance until depletion rather than gradually fading.

Sold as a single cell in child-resistant blister packaging, the CR1616 suits devices with shallow battery compartments where thicker CR2032 or CR2025 cells will not fit. The 3V nominal voltage matches the requirements of most coin cell devices, and the lithium composition gives the battery a shelf life of up to 10 years when stored at room temperature, making it practical to keep spares on hand for emergency replacement of key fob batteries or medical device cells.

The 16mm diameter and 1.6mm thickness make the CR1616 one of the thinner coin cells in common use — approximately half the thickness of a CR2016 and a third the thickness of a CR2032. This thinness is the defining feature when choosing between coin cell sizes: if a device specifies CR1616, thicker cells will not fit the compartment depth even if the diameter matches. The battery weighs just 1.2g and operates across a temperature range of -30°C to +60°C, covering typical indoor use and most outdoor conditions in the UK.

Frequently Asked

What devices use a CR1616 battery?

The CR1616 is commonly found in car key fobs, glucose monitors, fitness trackers, small LED keychain lights, calculator watches and some motherboard CMOS backup cells. Any device specifying a CR1616 requires this exact size — thicker coin cells like CR2032 will not fit the compartment.

Can I use a CR2016 instead of a CR1616?

No. The CR2016 is 2.0mm thick while the CR1616 is 1.6mm thick. Although both share the same 16mm diameter, the CR2016 will not fit in a compartment designed for the thinner CR1616 cell.

How long does the battery last?

Battery life depends on the device's power draw. In a typical car key fob with occasional use, a CR1616 may last 2-4 years. In a continuously-running fitness tracker, expect 6-12 months. The shelf life when unused is up to 10 years.

Is the packaging child-resistant?

Yes. The blister pack is designed to meet child-resistant packaging standards, requiring deliberate twisting or cutting to access the battery. Keep out of reach of children — swallowed batteries can cause serious internal burns.
