Samsung is increasing the capacity and this time it is a 4.20V cell, not 4.30V or 4.35V cell. The cell is not for high current usage.

New quality cells, the two cells match nearly perfect. Capacity do vary slightly with load.

Conclusion

The cells are fairly good at keeping high output voltage, even when loaded.
Being Samsung they are very good cells.

Thanks a lot for another great cell test!

As of today I count 243 tested cells in your 18500/18650/26650 comparator. This is awesome.

...

Err, you don't happen to have the Samsung INR18650-35E in your pipeline... This should be the direct successor to the 32E, supposedly the same chemistry. I saw the 35E pop up at a shop 2 days ago and am veeeeeeery curious...

It is about 3½ years work.

Not directly, but I am going to test it.

Wow.
But it’s really really helpful to tell a spade from a bloody shovel.
Too many dangerous cells out there.

Thanks HKJ.
This cell looks very nice. Better than LG MH1 3200, Pana BD 3200 or any other 4.2 cell I’m seeing at normal amps.

Hi ,HKJ

Thanks for your test/review

The Samsung INR18650-32E seems the upgrade version of ICR18650-32A with 4.35V charging voltage.Or it come to compete with LG INR18650 MH1 3200mAh ?

Which is better of this two types .Any comparation for them?

18650 battery is the best

You can compare any two 18650s that HKJ has tested here http://lygte-info.dk/review/batteries2012/Common18650comparator.php He also has comparators for other sizes.

According to the comparation.It seems the INR18650-32E is little bit better than LG MH1.

18650 battery is the best
