This is a high current battery with fairly low capacity by todays standard (Datasheet is from 2007)










The battery do fine up to 20A with nearly constant capacity, but it cannot handle 30A.



















Conclusion

This is an older high current cell for tools, the last 10 years has improved cells significantly.
