Test/review of LG 18650 HD4 2100mAh (Orange)

LG 18650 HD4 2100mAh (Orange)

Official specifications:

  • Nominal voltage: 3.6V

  • Maximum voltage: 4.2V

  • Maximum continuous discharge current: 25A

This is a high current battery from some years ago.

Very nice discharge curves

30A is too much for the battery it get rather hot.


This was a very good tool battery in its time, today batteries have more capacity and some batteries are a bit better for high current.

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

Compare to 18650 and other batteries
