3M Versaflo TR-300 PAPR - Batteries Expected Life

3M™ Versaflo™ Powered and Supplied Air Respiratory Systems
Batteries Expected Life
 Approximately 250 full capacity charge/discharge cycles (based
on maintaining 80% of the capacity in a new battery pack).

1 cycle = discharge of 90%

1 cycle = discharge of 90%
 Partial cycles are counted and added up until 90% is reached
 Ex: User runs battery pack for 2 hours and depletes it 20%. User

each day. 1 cycle has occurred (5 days use)
 20% discharge/day X 5 days use = greater than 90% discharge;
battery will register 1 cycle after 5 days
