Fenix RCR123A/16340 800 mAh

Product detailed description

The RCR123A rechargeable battery is the same size as a disposable CR123A lithium battery, which is why it is often used in flashlights as a rechargeable alternative to these disposable cells. It can now be charged by connecting a cable to the USB-C port, and its capacity has been increased to 800 mAh compared to the previous version. Li-ion technology offers one of the best ratios of stored energy to cell weight. The batteries have no memory effect, and self-discharge is minimal.

Battery protection can be divided into two areas. The first involves added electronic circuits that prevent overcharging (a situation where conventional Li-ion batteries face a risk of explosion) or, conversely, over-discharging (which would render the battery unchargeable). In addition, these circuits protect the battery against short circuits or high current draw, which could damage the battery. If the battery’s electronics detect that limit values have been reached, they disconnect the cell. The second area involves protection against overheating (PTC thermal protection) and a special anti-explosion valve.

Unlike other valves used in Li-ion batteries, this one, in the event that the gas pressure in the cell exceeds a certain limit, separates the electrodes inside the battery, thereby effectively interrupting the exothermic reaction and venting the excess gas pressure out of the battery. Thanks to the combination of electronic and mechanical (temperature and pressure) protection, Fenix batteries are among the safest Li-ion batteries available.

Fenix RCR123A USB-C:

• Weight: 18 g.
• Capacity: min. 800 mAh (2.88 Wh).
• Nominal voltage: 3.6 V.
• Built-in USB-C connector for easy charging; charging time approx. 2 hours.
• Equivalent to a CR123A disposable battery.
• Protective electronics built into the positive terminal provide protection against overcharging, complete discharge, and short circuits.
• Compatible with the Fenix HM51R headlamp.
• Maximum current draw: 3C (2.4 A).
• Maximum charging current: 0.6 A.
• Lifespan of 500 charge cycles until capacity drops to 70%.
• Length 35 mm, diameter 16.7 mm.

Charging:

• Via USB-C connector: Plug the USB cable into the side USB-C connector; during charging, the indicator light on the top of the battery glows red. Once fully charged, it glows blue. A completely discharged battery takes approximately 2 hours to charge.
