  • Charging Time Standard charge: 5hours
  • Max. Charge Current: 3,200mA (not for cycle life)
  • Max. Discharge Current: 6,400mA (for continuous discharge), 9,600mA (not for continuous discharge)
  • Discharge Cut-off Voltage: 2.50V
  • Cycle life: 500 cycles to 70% with 3200mA discharge, 300 cycles with 6200mA discharge.
  • Cell Weight: 50g max
  • Cell Dimension: Height : 65.2mm max, Diameter(max.) : Ø 18.50 mm
  • Operating Temperature (Cell Surface Temperature): Charge : 0 to 45°C, Discharge : -20 to 60°C
  • Storage Temperature: 1 year : -20~25°C, 3 months : -20~45°C, 1 month : -20~60°C




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...

HKJ is awesome :) Thanks.

It is about 3½ years work.

Not directly, but I am going to test it.

Love your reviews HKJ!

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

:beer: Thx

Thanks for the review, your work is amazing.

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?

You can compare any two 18650s that HKJ has tested here Battery test-review 18650 comparator He also has comparators for other sizes.

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