7-STAGE AUTOMATIC CHARGING
(GEL, AGM, WET & Calcium)
Intelli-Charge incorporates the latest technology to deliver a 7-stage charge suitable for
automotive, calcium, marine and all types of deep cycle batteries (Gel and AGM). These
stages of charging ensure maximum battery life and performance are delivered with a
faster charging time and ensure a complete charge is achieved.
The 7 charge stages are:
Desulphation; Soft Start; Bulk; Absorption; Analysis; Recondition and Float.
1. DESULPHATION
Rejuvenates sulphated
batteries with a high
frequency pulse.
2. SOFT START
Increases battery life
by gently starting to
charge the battery.
3. BULK CHARGE
Reduces charging
time by delivering
maximum charge to
set voltage.
4. ABSORPTION
Ensures a full
charge to the
battery without
overcharging.
EQUALISATION
(Calcium mode only)
Returns a full
hydrometer reading
to calcium batteries
by removing acid
stratification.
5. ANALYSIS
Tests the battery to
ensure fully charged.
6. RECONDITION
Restores battery
health to deeply
discharged batteries
by equalising
the cells.
7. FLOAT
Float charge
maintains the
battery at 100%
charge.

DESULPHATION
The Desulphation stage is designed to break down sulphation occurring in batteries
that have been left flat for extended periods of time, returning them back to full charge.
Sulphation occurs when lead-sulphate hardens and clogs up the battery cells.
SOFT START
This is a preliminary charge process that gently introduces power to the battery,
protecting the battery and increasing battery life.
BULK (CONSTANT CURRENT)
The Bulk stage reduces charging time by charging the battery at the maximum rate (constant
current) to a set voltage, at which point the battery is approximately 80% charged.
ABSORPTION (CONSTANT VOLTAGE)
The absorption stage charges the battery to 100% by adjusting the charge rate allowing
the battery to absorb more power.
EQUALISATION (CALCIUM MODE ONLY)
Designed especially for calcium batteries, this stage returns calcium batteries to full
service by removing acid stratification of the electrolyte.
ANALYSIS
The analysis mode tests the battery to ensure that it has taken the charge; if the
battery passes the test the charger will proceed to the float stage, but if the battery
fails the test, the charger will apply a recondition charge to try to return the battery
to full charge.
