• When to equalize
Once the interval setpoint (battery equalization cycle) is reached, or the equalization cycle is activated immediately in
float stage, the controller will initiate the equalization process.
• Equalization charging time and timeout
During this process, the controller will supply power to charge battery and hold it there until the voltage reaches the
set equalization point. Then, the timer will enter a constant voltage stage which requires the battery to be held at the
equalization level until the cycle time expires.
However, when the cycle time expires and the battery voltage fails to reach the equalization point, then the time will
be extended to ensure that this occurs. If battery voltage drops below the equalization voltage when the timeout is
reached, the charger will then return to Float to prevent battery damage.
