Step 3: Recovery
Recovery algorithm following a deep discharge.
Step 4 : Charge
Maximum current fast charge to reach an 90%
charge level.
Step 5: Absorption
Constant voltage charge to reach a 95% charge
level.

Step 6: Absorption
Constant voltage charge to reach 100% charge
level.
Step 7: Refresh (only for liquid profile)
The charger supplies an additional current to create
gas that will allow the electrolyte to be mixed and
thus reconditioning the battery cells. During this
phase, the battery may produce some water.
Step 8 : Maintenance/Floating charge
Maintains battery charge level at its maximum.

Step 7 : Supplement
Reduce current charge to reach 100% charge level.
Step 8: Equalization / Balancing
Balancing the battery cells
Step 9: Maintenance/Floating charge
Maintain the battery charge level at its maximum.
