Operation
Absorption Stage
This is a timed constant-voltage stage. It uses only enough current to maintain the Absorb voltage
(usually requiring a tapering current). It "tops off " the batteries at effectively 100% SoC.

Status message:
Absorption
Voltage Used:
Absorb voltage (V)
setting. For the three-stage cycle to proceed
normally, this setting should be kept higher than the
Float voltage (V)
and
Rebulk voltage (V)
settings.
Exiting to Float stage:
Upon reaching the
Absorb time (m)
or
Absorb end amps (A)
setting.
Time limit:
Absorb time (m)
setting. The timer counts down from the inception of Absorption
stage until it reaches zero. The time remaining can be viewed in Figure 28.
The charger may not always run through the timer’s full duration.
The timer may expire early if the starting time was left over from a previous cycle.
The charger will leave Absorption if the charging current tapers down to the
Absorb end amps (A)
setting. This prevents holding the battery at a high voltage
for unnecessary amounts of time. The timer will retain any remaining time and use
it on the next cycle.
The Absorption timer does not reset to its maximum amount, or to zero, when AC power is
disconnected or reconnected. It only goes to zero if the timer runs out during Absorption stage
.
In other cases it retains any remaining time for use on the next cycle.
Absorb time (m)
is reset to its maximum amount whenever the battery voltage decreases to the
Rebulk voltage (V)
. The reset occurs immediately, regardless of the time spent below this point.
To skip this step:
Setting
Absorb time (m)
to a short duration causes the charger to spend minimal
time in Absorption once the Bulk stage is complete.
Setting
Absorb time (m)
to zero will cause the charger to proceed directly to Float stage.
This may not be desired if the intent is to skip Absorption but retain the Bulk stage.
Setting
Absorb Charge Mode
to
Disable
also causes the charger to skip both
stages and proceed directly to the Float stage.
