Samsung INR18650-32E 3200mAh (Cyan)
Official specifications:
Typical Capacity: 3,200mAh (0.2C, 2.50V discharge)
Minimum Capacity: 3,100mAh (0.2C, 2.50V discharge)
Charging Voltage: 4.2V
Nominal Voltage: 3.65V (0.2C discharge)
Charging Method: CC-CV (constant voltage with limited current)
Charging Current Standard charge: 960mA
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.

Compare to 18650 and other batteries
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.
Wow.
But it’s really really helpful to tell a spade from a bloody shovel.
Too many dangerous cells out there.
Thx

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.
