STEP 4 – Disconnect Charger from Battery

If the battery is

out of the vehicle:

Switch OFF and remove the AC power socket from the outlet.

Remove the black lead and then the red lead.

Check electrolyte levels if possible.

(As they may need topping up with distilled water after charging)

If the battery is

in the vehicle:

Switch OFF and remove the AC power socket from the outlet.

Remove the lead from the vehicle chassis.

Remove the lead from the battery.

Check electrolyte levels if possible.

(As they may need topping up with distilled water after charging)

THE CHARGING PROCESS:

The charging stages and performance are as follows:

Battery initial condition check

After all connections are made, the charger will automatically diagnose

battery condition.

If battery voltage is above 9V, charger will go into soft start stage.

Otherwise, charger will go into desulphation mode. If the battery voltage

does not exceed 9V after 6 hours of rejuvenation, you will need to

disconnect the battery and check its condition, voltage rating or if it is

connected to a load while charging.

Smart Charging Stages

Desulphation:

20% charging LED: ON.

Engage high peak pulse for deep-discharge or sulphated battery

dissolve the lead sulphated crystal bring the electrolyte fluid to

well-distributed state

The battery voltage will increase slowly.

Soft start:

20% charging LED: ON.

The battery voltage will increase slowly.

Bulk :

80% charging LED: ON.

The battery can be charged about 80%.

The charger delivers an almost constant current 2000mA until the

battery voltage reaches the set value.

Absorption :

80% charging LED: ON.

The battery can charge up to almost 95%.

The charging current tapers and the charging voltage are kept

constant at the set value.

Test Mode

The charging is interrupted for a short period while battery voltage

is measured.

If the battery voltage falls too quickly, the battery could be faulty.
