BATTERY CHARGING
Gel cell and Advanced AGM batteries can accept a higher rate of charge. Consult the manufacturer for specifications.
Stage 2 - Acceptance Charge The acceptance stage immediately follows the bulk charge stage. During this stage the battery voltage is held constant at the bulk charge voltage limit and the current gradually ramps down. During this stage the battery is accepting its final amount of charge current and the last of the sulfate on the plates is removed.
The acceptance stage lasts until the charge current reaches the transition point. A timer will terminate the acceptance stage if this current level is not reached.
ACCEPTANCE TO FLOAT TRANSITION POINT
15 Ampere DC |
Maximum acceptance time is one hour for wet and AGM cells and three hours for gel cells. Gel cell acceptance time can be longer because they are less likely to gas. Expect wet cell batteries to gas somewhat during
Stage 3 - Float Charge When the acceptance stage is terminated, either because the charge current ramped down to the transition point or the timer engaged, the charge current will shut off. The unit monitors the battery voltage while it drifts down from the acceptance charge voltage limit. When it reaches the float voltage set point, the float charge stage is engaged.
The float charge stage holds the battery voltage constant at a preset lower level, where it is safe for
The battery charger remains in the float charge stage indefinitely until the charger is disconnected from incoming AC power or turned OFF on the unit or with the Remote Control Panel.
Stage 4 - Equalizing Charge This is the only battery charger stage which is not engaged automatically. It must be manually initiated each time. Applying an equalizing charge is possible only with a Remote Control Panel.
Periodic equalizing is recommended by most wet cell
