October 9, 2019 

Thismode covers both constant current and constant voltage modes and charges the battery to 
approximately 85% of its capacity in approximately 3 hours.  In this mode the charge indicator will be 
flashing green. Once 85% capacity has been achieved, the charging will automatically switch into “Stage 
2”.
