This is a No name battery from Ebay , was the cheapest money could buy .
Claimed capacity is 2200 mAh
I charged the battery in a genuine Canon Charger ..
After some rest the battery was 8.22 volt
I discharged @ 0.2A ( 200mAh ) to 6 volts and the resulting capacity ( to 6v ) was 1329 mAh

Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….
