Product Description:

Works in -40°

This cold resistant 18650 battery, from Klarus, is fitted with Li-ion chemistry that is suitable for use in extremely cold temperatures. Lithium-ion, in general, is the go-to choice for stability, when it comes to changes in temperature. Klarus has taken it to the next level by incorporating a new Li-ion formula that works in -40°! This cold resistant 18650 battery is, therefore, the perfect choice for powering outdoor electronics in the wintertime. Ice fisherman, for example, may deal with air temperatures that drop to below 0°F. The best time of day for ice fishing is when the moon is rising or setting, which means that you'll need a flashlight to see what you are doing and a power source that can handle the extreme cold temperatures! This is just one of the many reasons why this cold-resistant 18650 battery is a valuable addition to your arsenal.

No Battery Charger Needed

Not only is this 18650 battery perfect for cold-weather usage, but it is also easily rechargeable! The Klarus 18GT-LT29 UR battery is fitted with a built-in micro USB charge port into which a charging cable (sold separately) is inserted for effortless re-powering. There is no need to carry a separate battery charger with you to recharge the cell. All you will need is a micro USB cable and a power source, such as the 12V adapter in your car, to which you can connect the cable. This cold-resistant 18650 even includes an indicator light that notifies a user of the battery's charge status. A red light indicates that the charge is in progress, while green light is the sign of completion. This rechargeable 18650 battery, with its 8A discharge, cold-resistant formula, and built-in charge port, is the perfect power source for premium flashlights used in extreme environments.
