Nitecore NL2160: 21700 Round Batteries with 6000 mAh/21.6 Wh

Nitecore NL2160

Nitecore, a renowned name in the realm of flashlight technology, has introduced the NL2160 series, marking a significant advancement in rechargeable batteries. These 21700 round batteries, available in two models – NL2160 and NL2160HP – offer an impressive capacity of 6000 mAh and 21.6 Wh.

What sets the NL2160HP apart is its capability to handle a current of up to 20 amps, making it a high-performance option albeit at a slightly higher price point. On the other hand, the NL2160, with a maximum current handling of 8 amps, caters to users seeking a more budget-friendly choice without compromising on capacity.

Key Specifications:

  • Capacity: 6000 mAh/21.6 Wh
  • Models: NL2160, NL2160HP
  • Current Handling: NL2160 - 8 amps, NL2160HP - 20 amps
  • Charging Cycles: At least 500

Compared to conventional 21700 rechargeable batteries with 18 watt hours (5000 mAh, 3.6 V), the NL2160 series offers an impressive 20% increase in capacity. Nitecore also provides an intermediary solution with slightly more capacity (5300 mAh, 3.6 V) for users with specific requirements. Notably, Nitecore has decided to discontinue most of the smaller batteries from its range, signaling a focus on higher-capacity options.

An enhancement in the NL2160 series is the inclusion of information on charging cycles. Nitecore specifies a minimum of 500 cycles before any potential loss of capacity. This move towards transparency is commendable, as it provides users with a clearer understanding of the battery's expected lifespan and durability.

However, potential buyers should exercise caution when considering these batteries, as they may not fit all 21700 sockets. Compatibility issues even within the Nitecore family, particularly with the P series, highlight the importance of thorough research before making a purchase decision.

Availability and Pricing:

German retailers such as Selected Lights and KTL are now stocking both the NL2160 and NL2160HP, ensuring availability for users with different preferences and budgets. The NL2160 is priced at approximately EUR 29 ($32) at Selected Lights, catering to those looking for a cost-effective option. Meanwhile, the NL2160HP, with its higher current handling capability, is available for EUR 34 ($37) on Nitecore.de.

Pros and Cons:


  • High capacity - 6000 mAh/21.6 Wh
  • Two models catering to different current handling needs
  • Transparency on charging cycles (at least 500 cycles)


  • Compatibility issues - not suitable for all 21700 sockets
  • Uncertainty regarding specific battery model in the EDC35 flashlight

Critical Assessment:

The NL2160 series undeniably brings a substantial boost in capacity to the world of 21700 rechargeable batteries. The availability of two models provides users with the flexibility to choose between performance and budget, a commendable move by Nitecore to cater to diverse user needs. The transparency on charging cycles is a positive step, allowing users to make informed decisions based on the expected lifespan of the battery.

However, the issue of compatibility is a significant drawback. The warning about potential incompatibilities, even within the Nitecore family, raises concerns about the user-friendliness of these batteries. Users, particularly those with existing Nitecore flashlights, need to be cautious and conduct thorough research to ensure the NL2160 series is compatible with their devices.

The lack of clarity regarding the specific battery model within the EDC35 flashlight is also a point of contention. While the flashlight itself showcases the capabilities of the NL2160 series, the inability to identify the exact battery raises questions about user convenience and serviceability.


In conclusion, Nitecore's NL2160 series presents an exciting advancement in rechargeable battery technology. With a focus on high capacity and transparency on charging cycles, these batteries cater to users with varying needs. However, the issue of compatibility, especially within the Nitecore family, and the uncertainty surrounding the battery model in the EDC35 flashlight warrant careful consideration from potential buyers. The NL2160 series has the potential to revolutionize the flashlight industry, but users must approach their purchase with awareness and research to ensure a seamless integration with their devices.
