Desulphation
When a battery has not been charged for some time, the lead-sulphate within the
battery hardens. The desulphation stage is used to break this down and start the
process back to a full charge.
The 1st green LED in the top row flashes to indicate when in Desulphation and is
constant when complete.
Soft Charge
A non-harsh, ‘soft’ introduction of power to the battery, to help preserve the battery
life.
The 2nd green LED in the top row flashes to indicate when in Soft Charge and is
constant when complete.
Bulk Charge
The primary charging phase where approximately 80% of charging takes place.
The charger delivers maximum current until the terminal voltage has risen to the
battery’s preset level.
The 3rd green LED in the top row flashes to indicate when in Bulk Charge and is
constant when complete.
Absorption
The battery’s voltage is kept at its pre-set level. During this phase, the current is
gradually reduced so that the battery can absorb more power.
The 4th green LED in the top row flashes to indicate when in Absorption and is
constant when complete.
Analysis
The battery is tested to determine that it has been fully charged. If after analysis the
battery has been found to have not gained enough charge, then recondition charge
mode is applied to help bring the battery to full, healthy charge.
The 5th green LED in the top row flashes to indicate when in Analysis and is
constantly lit when complete.
Recondition
If a battery fails to fully charge, caused primarily by a battery low state of health,
BC15/BC25 automatically proceeds to the next step in the charging sequence, which
is reconditioning. If the battery has undergone 3 reconditions, yet still it has not
gained enough charge, charging is suspended and an error will be indicated.
The 1st green LED in the top row flashes when in Recondition mode.
