This battery is a high current battery of a fairly old type.










The battery has fairly constant capacity up to 15A.



Due to the fairly low capacity, the battery keeps a moderate temperature.













I used the capacity while doing these measurements.





Conclusion

The battery is orginally from 2006 or 2007 and was probably designed for use in electric tools.



Notes and links

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.

Over the next couple of months I expect to publish more reviews of older cell, there will also be some never cells that I am missing.
These test is done when I do not have never batteries to test.
