AmpMax 18650 3400mAh (Black)



Official specifications:

  • Built-in protection circuit, guards against - Over-charge, Over-discharge , Over-current and short-circuit
  • Triple MOS's for superior high current discharge
  • Improved voltage stability due to low internal resistance
  • PET sheath, environmentally friendly and not easy to crack
  • Voltage: 3.7V (4.2V when fully charged)
  • Capacity: 3400mAh
  • Standard charge current 1700mAh
  • Standard discharge current 680mAh

  • Standard discharge cut –off current 30mA
  • PCB protection trip current 10A
  • Dimensions:18 mm x 68.5 mm (+/-0.2 mm)
  • Weight: 48g




The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.



The battery is packed both in a box and in shrink wrap.



Very nice tracking between the two batteries.




















Conclusion

This battery has higher capacity and better high current capacity than its predecessor (3100mAh/NCR18650A).
With the added protection it is a very good battery.

Thanks for the review. Nice battery with virtually identical discharge curve as the Enerpower+ 3400mAh.
