Fenix ​​RCR123A rechargeable battery

Rechargeable Li-ion battery size RCR123A (16340) with a capacity of 950 mAh. It can be charged in rechargeable lamps and headlamps, but also in a classic external charger. It is particularly suitable for devices with higher current consumption, e.g. lights and headlamps Fenix ​​E18R V2.0, Fenix ​​HM50R V2.0, Fenix ​​HM51R V2.0, Fenix ​​Vitae, Fenix ​​PD25R. Li-ion technology gives one of the best ratios of the amount of stored energy to the weight of the cell. The batteries have no memory effect and self-discharge is minimal.

Battery protection can be divided into two areas. The first one adds electronic circuits that prevent the cell from being overcharged (a situation where there is a risk of explosion with classic li-ion batteries) or, conversely, from being over-discharged (the battery would then not be able to be recharged). In addition, these circuits protect the battery against a short circuit or high current consumption, which could damage the battery. If the battery electronics evaluates reaching the limit values, it disconnects the cell. In the second, there is protection against overheating (PTC thermal protection) and a special anti-explosion valve. Unlike other valves used in li-ion batteries, this one, when the gas pressure in the cell exceeds a certain limit, separates the electrodes inside the battery, thereby de-facto interrupting the exothermic reaction and releasing the excess gas pressure outside the battery. Thanks to the combination of electronic and mechanical (temperature and pressure) protection, the Fenix ​​battery is one of the safest Li-ion batteries available.

The RCR123A battery is the same size as the disposable lithium CR123A battery, which is why it is often used in lamps as a rechargeable alternative to these disposable cells. Before first use, check if your device supports this cell, as it has a higher nominal voltage than a disposable battery. These batteries can also be used in, for example, Fenix ​​E15 XP-G2, E16, Fenix ​​RC09, CL09, Fenix ​​PD22 Ultimate Edition and LD15R flashlights.

ATTENTION - do not use in Fenix ​​E15 (does not apply to E15 XP-G2), PD10, PD12, PD20, PD22 (does not apply to Ultimate Edition) and HL50, there is a risk of damage to the electronics!

Warning

  • If possible, do not discharge the battery below 2.5 V
  • Do not short-circuit the battery (do not connect the poles of the cell with a wire)
  • Do not throw the battery into fire or water
  • Never insert the battery into the charger upside down (opposite polarities)
  • When using the accumulator, pay attention to the safety principles
  • Use only an adequate charger supporting Li-ion batteries
