A BATTERY MOOCH POST: These tables are not “pulse” ratings for Sony VTC batteries!

They are maximum response time tables for the battery management/protection system for a battery pack that uses Sony VTC batteries. You can see this in the section heading, “Over current protective circuit”, and in the description for the tables.

These are one time, emergency use only, protection response times for different discharge overcurrent levels (covered in red). They cannot be used as pulse ratings or even maximum pulse capabilities for VTC batteries. They only ensure that the battery doesn’t explode or catch fire. The battery can still be damaged or vent.

An actual rating would tell you the rest time between pulses and the criteria used to set the pulse rating (voltage sag? max temperature? cycle life?).

Do not use these discharge current levels as any type of indicator as to how hard you can run Sony VTC batteries or what “pulse” ratings they might have.
