cr1616 battery equivalent mLithium CR1616 is very popular 3.0 volts lithium primary (non-rechargeable) battery, often used in car remote keys, wrist watches, TV remotes, medical equipment, calculators, digital scales and other small electronic devices.

Due to its very long shelf life and stable voltage, CR1616 is often used as memory battery in computers, cameras, game controllers and other electronic devices.

Lithium CR1616 is button/coin cell battery, featuring 16 mm (0.63 inches) diameter and 1.6 mm height (0.06 inches) - hence the '1616' as common part of the most labels. Common CR1616 battery weighs in the 1.1 and 1.3 grams range.

Common labels for CR1616 equivalent batteries are DL1616, BR1616, ECR1616, 280-209, GPCR1616, LiR1616, KCR1616, 5021LC etc. Most labels, but not all, include '1616' in the label to indicate the battery size.

CR1616 batteries feature negative electrode made of lithium, while positive electrode is commonly made of manganese-dioxide, and rarely made of or carbon-monofluoride.

Manganese-dioxide lithium batteries' labels start with 'C' (like CR1616).

Operating temperature range varies among the brands, but generally it is between -20°C (-4°F) and 70°C (158°F) - for example, Panasonic states for their very popular CR1616 batteries that their operating range is between -30°C and +60°C.

Nominal voltage of CR1616 batteries is 3.0 V, with a cutoff voltage typically around 2.0 V. Voltage drops over time, but it also depends on the battery load and temperature.

Capacity of CR1616 batteries varies, but the best and most reliable brands state capacity of their CR1616 batteries to be in the 50-55 mAh range.

Carbon-monofluoride lithium batteries' labels start with 'B' (like BR1616) and generally their operating temperature range is -30°C (-22°F) and 85°C (185°F).

BR1616 batteries are not so common these days since CR1616 batteries are improved over time, especially in terms of temperature range and shelf life.

Nominal voltage of BR1616 batteries is usually slightly lower than the voltage of CR1616 batteries (2.8 V vs 3.0 V), and a cutoff voltage is 2.25 V. Typical example is now obsolete Panasonic BR1616 battery, with typical capacity of ~48 mAh and temperature range of -30°C and +80°C.

Note: CR1616 batteries also tolerate stronger discharge currents when compared with BR1616 batteries, which is very important in devices that are used occasionally, for short periods of time - car keys, TV remotes, and similar.

Shelf life of high quality CR1616 is up to 10 years - that means that after being stored for 10 years, these CR1616 batteries will still hold 80-90% of their initial charge.

That is why most manufacturers package their CR1616 and similar batteries in 'child safe' packages which require some strength to be opened without tools of some kind. If these batteries are swallowed, induce vomiting right away and call emergency services and act according to their instructions!

And yes, this is a serious warning!


Long Story Short: If you are looking for a new CR1616 battery replacement for your car keys, wrist watch, TV remote, game controller and similar, go for the batteries from reputable brands like Panasonic, Duracell and similar. Their CR1616 batteries commonly come with 10 year shelf life, capacity in the 50-55 mAh range, and acceptable price.
