Description

Fenix Extended Runtime Kit for the TK75 Flashlights

Increase Your Light's Runtime

The Fenix Extended Runtime Kit is made up of (1) tube, or extender, and (1) battery magazine, which holds (4) 18650 cells (not included). The simple extension kit is designed for use with the Fenix TK75 LED flashlight and enables users with the ability to increase a light's performance. The TK75, on its own, runs on (4) 18650 batteries and can last for up to 270 hours, when in Low mode. The extended runtime kit doubles the number of batteries used from 4 to 8 cells and therefore increases the light's overall runtime. In fact, users can combine up to 3 kits together to create the ultimate long-lasting flashlight. As an added bonus, the Fenix extension kit offers a flat base for effortless tail-standing. Feel free to use your improved light as a candle during a power outage or a storm. Please note that in addition to elongating the runtime of the light, users are also lengthening its body.

Note:

Extended runtime kits position the batteries in parallel, increasing runtime while leaving voltage unaffected. However Fenix recommends using no more than three extended runtime kits per flashlight.
