Home > News & Events >News Introduce of Bulk Stage, Absorption Stage and Float Stage

Bulk stage:
During this stage the controller delivers as much charge current as possible to rapidly recharge the batteries.
 
Absorption stage:
When the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode.
When only shallow discharges occur the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged. Additionally, the absorption period is also ended when the charge current decreases to less than 2A.
 
Float stage:
During this stage, float voltage is applied to the battery to maintain it in a fully charged state
