Test/review of Samsung ICR18650-24F 2400mAh (Green)

HKJ · 24.05.2018, 18:02

Samsung ICR18650-24F 2400mAh (Green)

Official specifications:

Nominal voltage: 3.70V
Nominal capacity: 2400mAh
Discharge cut-off: 2.75V
Standard charge current: 1.55A
Maximum charge current: 2.15A
Maximum continuous discharge: 5A

A medium capacity cell with standard current capabilities.

The discharge curves are very nice, the match nearly perfect and capacity is constant up to 7A, this is fine for a 5A rated cell.

Conclusion

This is a good quality cell, but performance is not very impressive by todays standards.

Notes and links

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

How is the test done and how to read the charts
How is a protected LiIon battery constructed
More about button top and flat top batteries
Compare to 18650 and other batteries

HKJ, battery released Aug 2011. Battery for almost 7 years has not lost capacity. When was the test conducted?

November 2017. I got a pile of old battery types, but they are probably manufactured more recently.

HKJ, the marking on the battery indicates that it is manufactured - Aug 2011 (1B82). As far as I know these batteries have long been removed from production, so it turns out that the batteries do not lose capacity over the years, as many people claim!

The battery 2011g. !!
And what is his inner resistance now?
And what kind of Datasheet?

They must have been stored correctly. As you can see I have published other reviews of older batteries and none of them are bad.

I do have a field with calculated resistance.
For some of the older batteries I can find the datasheet, for this I found a website listing the data, it looked to be directly from the datasheet.
