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.

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