4. Charging Stages:
The VMAXTANKS™ HD chargers offer a fully automatic 7-Stage charging process-Desulphation, Soft Start, Bulk, Absorption, Battery Test,
Recondition and Float- offering a very comprehensive and accurate charging process. This lengthens battery life and improves their
performance.
VMAXTANKS™ HD chargers are suitable for most battery types designed to be charged with 2.45V/Cell including Calcium, Gel and AGM batteries.
They may also help restore drained and sulphated batteries.
Desulphation
The Desulphation stage may break down sulphation that occurs in batteries that have been left flat for extended periods of time, bringing them
back to full charge. Sulphation occurs when lead-sulphate hardens and clogs up the battery cells.
Soft Start
Soft Start is a preliminary charge process that gently introduces power to the battery. This protects the battery and increases battery life. This
stage continues until the battery's terminal current has risen slowly above the set limit of soft start current, at which point the charger switches
to bulk charging.
Bulk (Constant Current)
Bulk mode charges the battery at the maximum rate (constant current) putting a large amount of power into the battery in a short amount of
time. This stage will charge the battery to approximately 80%, until the voltage reaches 14.5-14.7 volts for 12V charger or 29.0-29.4 volts for 24V
charger.
Absorption (Constant Voltage)
The charge rate slows down so the battery can absorb more power and reach 100% charge. The voltage remains at a constant 14.7 volts for a 12V
charger or 29.4 volts for a 24V charger while the current is gradually reduced until no more power can be added without over-charging the
battery.
Battery Test
An automatic battery test is conducted immediately after the absorption 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.
12V charger: If the voltage is above 13.2 volts (pass), the charger will proceed to the final stage: Float
24V charger: If the voltage is below 26.4 volts (fail), the charger will initiate the Recondition stage.
24V charger: If the voltage is above 26.4 volts (pass), the charger will proceed to the final stage: Float.
Recondition
The battery recondition function is initiated automatically if the battery fails the battery test (stage 5). Failing the battery test indicates that
