Test/review of LG 18650 ME1 2100mAh (Orange)

LG 18650 ME1 2100mAh (Orange)







Official specifications:

  • Nominal capacity: 2100mAh

  • Minimum capacity: 2050mAh

  • Nominal voltage: 3.65V

  • Maximum discharge current: 4200mA (2C)

  • Maximum charge current: 2100mA (1C)




This is an older LiIon cell with fairly low capacity and moderate current capability.










The two cells match perfectly and they can more than rated current.





















Conclusion

Some time ago this was a very good cell that could deliver a moderate current, but capacity is not up to today’s standard and most batteries can deliver more current today.



Notes and links

I saw some specifications say it is 4.35V cell, they must be wrong. I tested at 4.20V and got the rated capacity!

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.

Compare to 18650 and other batteries

You say you “tested at 4.20V and got the rated capacity!” but did you also try testing at 4.35V to see what would happen? :smiling_imp:

It will probably get 15-20% more capacity.

Or maybe it will just become a fission reactor in a radius of 1m :smiling_imp:

No, I do not like to apply much over voltage to batteries.
The result will be slightly more capacity and much shorter lifetime for the battery. Battery will probably not vent at 4.35V.
