Absorption:
After the bulk stage, the charger will automatically begin to reduce its current output whilst maintaining
the required voltage (depending on the battery selection). When the current reaches a pre-determined
threshold level, charging will halt allowing the next analysis stage to be performed.
Analysis (Testing the battery whilst charging):
After the absorption stage, the battery charger will start the analysis stage and will stop charging the
battery for approximately 1 minute. At this point, if the battery passes this test without any faults
detected, it will then move to the next boost stage. However, if the battery voltage drops too quickly past
set parameters, the battery LED indicator will flash and the red and grey terminals in the LED display will
also be flash. If this occurs the battery should be replaced.
Boost:
After a successful result from the analysis stage, the charger will now enter the Boost stage where volt-
age is increased to maximum and the current is reduced to approximately 25% of the rated output. This
stage brings the battery safely up to a 100% fully charged state.
Maintenance:
This stage evens out voltage between all cells and will maintain a constant pulse voltage with a very
small current. This stage will remain on indefinitely whilst the battery is connected and is perfect for
long term maintenance for vehicles or stand-alone batteries that will not be used for long periods of
time such as winter storage. Keeping your battery on a maintenance charge will ensure it is always 100%
charged and in turn will reduce the chance of sulfation, extending battery life and serviceability. During
long term maintenance, it is important to periodically check fluid levels in the battery if it is NOT a sealed
or maintenance free design.maintenance charge will ensure it is always 100% charged.
Disconnecting the charger from a battery:
1. Always turn off and unplug the charger from the mains power supply before making or
breaking connection to the battery.
2. Remove the black negative (-) then the red positive (+) of the battery charger from the
battery or unplug the terminal connector lead.
3. Re-inspect the electrolyte levels in the battery and top up if required (non-maintenance free
and non-sealed battery types only).
