1 - Desulphation
The Desulphation stage may break down sulphation that occurs
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.
2 - Soft Start
A preliminary charge processes that gently introduces power to
the battery. This protects the battery and increases battery life.
3 - Bulk
Charging with maximum current until approximately 80% battery
capacity. Bulk mode for the charging cycle. The start phase con-
tinues until the battery’s terminal voltage has risen above the set
limit, at which point the charger switches to bulk charging. If the
terminal voltage has not passed the voltage limit within the time
limit, the charger switches to fault mode (Step 3 lamp solid)
and discontinues the charging. If so, the battery is faulty or its ca-
pacity is too large.
4 - Absorption
Charging with declining current to maximize up to 100% battery
capacity.
5 - Analyse
An automatic battery test is conducted immediately after the ab-
sorption stage. The test monitors the voltage for 90 seconds to
determine if the charge was successful.
•
12V charger If the voltage is below 13.2 volts (fail), the
charger will initiate the Recondition stage.
