Description

The Panasonic CR2016 is a 3V lithium coin cell battery measuring 20mm diameter by 1.6mm thickness, supplied in a value pack of six cells. Each battery uses Panasonic's lithium chemistry to deliver stable voltage output across its discharge cycle, making it suitable for low-drain devices that require consistent power over extended periods.

Designed for watches, calculators, car key fobs, medical instruments, fitness trackers and small LED lights, the CR2016 operates across a temperature range of -20°C to +65°C without significant voltage drop. This makes the battery suitable for devices stored in cars, outdoor equipment and pocket-carried electronics that experience temperature fluctuation. The 3V nominal voltage matches the requirements of most coin cell devices manufactured for CR2016 compatibility.

The blister pack contains six individual cells with child-resistant packaging that requires adult force to open. Each cell is hermetically sealed to prevent leakage and maintain shelf life. The CR2016 designation is consistent across manufacturers, and these Panasonic cells are also compatible with devices specifying BR2016, SB-T11 or 280-202/4 battery types, which are alternative naming conventions for the same 20mm x 1.6mm lithium coin cell format.

Panasonic manufactures these batteries with mercury-free, cadmium-free chemistry in line with EU battery directive compliance. The cells deliver typical capacity of 75-90mAh depending on discharge rate and operating temperature, with higher capacity at moderate temperatures and lower drain rates. For devices with intermittent use such as watches or calculators, a single CR2016 typically provides 2-3 years of service before replacement is needed.

Frequently Asked

What devices use CR2016 batteries?

CR2016 batteries power watches, calculators, car key fobs, fitness trackers, small medical devices like glucose meters, LED keychain lights, and motherboard CMOS memory backup. Any device with a 20mm x 1.6mm coin cell compartment marked CR2016, BR2016, SB-T11 or 280-202/4 will accept these batteries.

How long do CR2016 batteries last?

Shelf life is typically 10 years from manufacture when stored at room temperature. In-device lifespan depends on power draw — a watch may run 2-3 years on a single cell, while a key fob with frequent button presses may need replacement after 1-2 years. High-drain devices like LED lights will deplete the battery faster.

Can CR2016 be used in place of CR2032?

No. CR2032 batteries are 3.2mm thick, while CR2016 are 1.6mm thick. The diameter is the same (20mm) but the thickness difference means CR2016 will not make proper contact in a CR2032 compartment. Always match the exact cell size specified by your device.

Are these batteries rechargeable?

No. CR2016 lithium coin cells are single-use primary batteries and cannot be recharged. Attempting to recharge a non-rechargeable lithium cell can cause leakage, overheating or rupture. Dispose of spent cells according to local battery recycling guidelines.
