Test/review of LG 18650 HB3 1500mAh (Gray)

LG 18650 HB3 1500mAh (Gray)







Official specifications:

  • Nominal capacity: 1500mAh

  • Minimum capacity: 1500mAh

  • Nominal voltage: 3.65V

  • Standard charge: 750mA, 4.2V, cut-off: 50mA

  • Fast charge: 4000mA, 4.2V, cut-off: 100mA

  • Standard discharge: 300mA

  • Fast discharge: 10000mA

  • Max. continuous discharge: 22000mA

  • Discharge cut-off voltage: 2.5V

  • Cycle life: 400 cycles to 75% at 10A discharge

  • Operating temperature: Charge 0°C ~ 50°C, Discharge: –20°C ~ 75°C

  • Storage temperature: 1 month: –20°C ~ 60°C, 3 month: –20°C ~ 45°C, 1 year: –20°C ~ 20°C



This is a high current cell from 2012










The capacity is on the low side and the curves do not match, I wonder if it is due to the age of the cell.
It can still deliver 20A, but with some voltage sag.



















Conclusion

For its time is was a nice tool battery.



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

I just picked up a bunch of LG M26 on sale. Any test data on them?

No, I have not got any yet.

Thank you sir.
