Nitecore 3400mAh High Capacity Battery:

If you have a device and are looking for a battery powerful enough to maximize your devices performance, look no further. Nitecore is one of the worlds leading manufacturers of rechargeable Li-Ion batteries. The NL189 Li-Ion 18650 battery offers both internal and external safety features to protect from overcharging, short circuiting, over discharging, and more!

If you are looking for an 18650 battery for your flashlight, Nitecore will ensure your flashlight gets the maximum light output available. If you are unfamiliar with the ratings on an 18650 battery, as a rule of thumb, the higher the mAh value the longer your flashlight will run. A battery's mAh rating refers to the capacity of the battery's cell, i.e. a 3400mAh battery will operate your flashlight longer than a 2300mAh battery.

  • Nitecore D4 4-Bay Battery Charger:

    Throw out all of your old battery chargers! Nitecore's D4 Digi-Charger is an all-in-one battery charger with brains. In addition to being smart, it is extremely versatile! Nitecore's D4 Digi-Charger works with almost all types of batteries including IMR, Li-Ion. Ni-MH, Ni-Cd, and LiFePO4. Like everything Nitecore makes, this charger is extremely high quality!

    Crystalline Display Nitecore's D4 features a sleek crystalline LCD which displays charging progress, battery type, voltage and more! The high contrast white on black LCD makes reading battery data very easy.

    Compatible: The D4 is even smart enough to recognize when there are different battery chemistry and sizes, and adjusts accordingly. That means you can charge a Li-Ion 18650 battery, and a Ni-MH AA battery at the same time!

    Intelligence: The D4's integrated micro-controller automatically identifies battery types and selects the appropriate charging voltage and current. Then, it detects the battery's status and initiates the appropriate charging mode (CC, CV, or -dN/df).

    IMR Safe Circuitry: Nitecore's D4 incorporates an optimized IMR charging system that is able to monitor the entire charging process ensuring the end voltage is always within safe limits, ultimately extending the battery's longevity.
