This is a rather unknown battery size for many people. It is used for a lot of stuff, mostly battery packs, but may also be used inside regular C or D cell of the low capacity types.








The discharge curves tracks nicely for NiMH and the capacity is good.















[size=+3]Conclusion[/size]

It is a good cell for battery packs, but I would prefer not to have it in my C or D cells.

This cell has been replaced by BK300SCP with about the same specifications.
