Test/review of Gpower IMR18350 700mAh (Purple)

Gpower IMR18350 700mAh (Purple)







Official specifications:

  • Battery Capacity (FastTech Tested): 708.8 mAh

  • Battery Capacity (Mfg Rated): 700 mAh

  • Battery Chemistry: IMR - LiMn

  • Battery Feature: Rechargeable

  • Battery Form Factor: IMR 18350

  • Battery Rated Voltage: 3.7 V




This is a high current 18350 cell.











There is a small capacity difference between the cells, i.e. they cannot be used in series.





As is usual the case with small cells, the temperature stays reasonable. They mau be very hot inside, but the heat do not have time to move out.















Conclusion

The cell has good high current capability, but like all 18350 high current cells the capacity is fairly low.
For stand alone usage it looks fairly good.

Thanks for the review!

I have been curious about small cells like 16340 or 18350. Are they have only 2 type, IMR and ICR?
