Excellent long lasting charge, highly recommended


This battery is a fantastic piece of kit life is very good in my torch


I ordered a battery and I got a battery 🤪


Very good performance holding charge for turbo mode compared to my amazon sourced trufire



Fantastic battery, I’ve used many AW, Nitecore and Samsung batteries. In terms of capacity this is a great battery! Best I’ve used... used it for a few days for light work, then used it to illuminate the living room @ 960 lumens (turbo mode on an SRT 7) for an hour. When I came to charge the battery it was still at 4.02v which surprised me massively. Usual great service from Flashaholics.



The Nitecore NL1835HP is a Li-ion 18650 with a protection circuit, 3500mAh and 8A output. The rechargeable cell has a continuous discharge up to 8A, making it suitable for high power 18650 based torches. 

The battery has several internal safety features, including a pressure relief valve protection, a microporous barrier to protect delicate internal components and built-in PTC inhibiting high current surges. Externally, the battery is equipped with nickel-plated stainless steel protectors to ensure high impact and oxidation resistance.

Please note: These are longer than regular Nitecore 18650 and as such are not compatible in the old TM series lights such as the TM26 and TM26GT.


  • Never expose to water or fire
  • When charging or using, ensure the positive and negative ends correspond with the positive (+) and negative (-) symbols
  • To extend battery like it is recommended that the NL1835HP is charged every three months when unused for long periods
  • Keep out of reach of children
