Stage 2—Acceptance Charge
The acceptance stage immediately follows the bulk charge
stage. During this stage the battery voltage is held constant at
the acceptance charge voltage limit and the current gradually
ramps down. The battery accepts its final charge current and
the last of the sulfate on the plates is removed. This com-
pletely charges the battery.
The acceptance stage lasts until the charge current reaches the
float transition point or until the maximum acceptance time is
reached.
Acceptance to Float Transition Points
Model Maximum Output Current
Freedom 10 10 Amps DC
Freedom 15 & 15 S/D 12 Amps DC
Freedom 20 & 20 S/D 15 Amps DC
Freedom 25 D/D 15 Amps DC
Freedom 30 D/D 15 Amps DC
Acceptance Time Limits
A timer will terminate the acceptance stage if float transition
current level is not reached. The acceptance stage timer is
automatically disabled when you use a LINK instrument.
The selected battery type determines the acceptance stage time
limit. Maximum acceptance time is:
• Wet cell batteries: 1 hour. Wet cell batteries will gas
during acceptance. This is a necessary part of the charging
process.
• Gel cell batteries: 3 hours. Gel cell acceptance time is
longer because they are less likely to gas.
• AGM batteries: 1 hour.
