Dobíjacia USB batéria Fenix 18650 3500 mAh (Li-ion)

Fenix ​​18650 3500 mAh (L18-3500U) rechargeable battery featuring a built-in micro-USB charging port. It can be charged by connecting a cable to the micro-USB port 
(e.g., from a computer or mobile phone charger) or in a standard battery charger. Li-ion rechargeable batteries are characterized by very high capacity and are free 
from memory effect and self-discharge issues. In terms of energy storage relative to size and weight, 18650-sized Li-ion batteries are the best choice.

Tip: If you need to charge multiple batteries simultaneously, you might find a four-way micro-USB charging cable useful.

Fenix ​​battery protection consists of internal safety mechanisms and protective electronics. Added electronic circuits prevent overcharging, over-discharging, 
short-circuiting, and excessive current draw. If the battery's electronics detect that limit values ​​have been reached, the cell is safely disconnected.

Internal protection consists of a separator, overheat protection (PTC thermal protection), and a special explosion-proof valve. If the gas pressure inside the cell exceeds a certain 
threshold, the internal separator separates the electrodes within the battery—effectively halting the exothermic reaction—while the explosion-proof valve vents the excess gas 
pressure out of the battery. Thanks to this combination of electronic and mechanical (thermal and pressure) protection, Fenix ​​batteries rank among the safest Li-ion batteries 
available.

In terms of size, the 18650 battery is roughly equivalent to two CR123A lithium batteries; consequently, it is frequently used in flashlights as a rechargeable alternative to these 
primary cells. Please verify beforehand that your device supports this cell. This battery is designed for use in devices such as the Fenix ​​E28R, E30R, and E35 UE (not compatible 
with the E35 V3.0), as well as the PD32 V2.0, PD35, TK11 TAC, TK15, TK16 (1000 lm version only), TK25 UV, TK25 IR, TK25 Red, TK25 R&B, TK26R, TK75, FD41, LD30, SD11, and SD20 
LED flashlights. ...for Fenix ​​LED headlamps HL55, HL60R, HP25R (1000lm version only), HP30R (1750lm version only), HM60R, HM61R, HM65R, HM65R-T; lanterns CL26R, CL30R; 
and Fenix ​​bike lights BC21R and BC30.

Note: Due to its 70 mm length and diameter, it may not fit certain older models—such as the Fenix ​​PD31, PD32 XP-G2, TK11, TK21, TK30, Zebralight, or Solarforce. 
The battery is also incompatible with the Fenix ​​FD65 model.
