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.



















[size=+3]Conclusion[/size]

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