Stage 2 – Absorption charge (70-90 % charge)
Maintain the charge at a constant safe voltage. During this stage, the
charging voltage remains constant, while the actual charging current
is reduced to allow for the maximum proper internal chemical energy
transfer. The charging LED lights.
Stage 3 – Top-off charge (90-100 % charge)
Voltage is automatically maintained and reduced to a predetermined
level while current is adjusted for a safe, effective 100 % charge
(step-down regulation mode). Ideal for topping off batteries that
have been in storage. Automatic shut-off at 100 % charge. The
charger will never overcharge any battery, or cause pressure leaking
of acid, even if it is left unattended while charging in hot summer
temperatures. The full LED lights.
5.4 Charging Batteries in Vehicles
1. Make sure the battery charger is not yet connected to the mains.
2. Connect the charger to the vehicle’s battery. Stay clear of fan
blades, belts, pulleys and other parts that can cause injury to
persons. Determine which battery terminal is grounded to the
chassis.
o Negative terminal is grounded: Clamp the positive terminal
clamp (red) of the charger to the positive terminal on the
battery. Then, clamp the negative terminal clamp (black) of the
charger to the chassis or engine block, away from the battery.
Do not connect to the carburettor, fuel lines or sheet metal
body parts.
o Positive terminal is grounded: Clamp the negative terminal
clamp (black) of the charger to the negative terminal on the
battery. Then, clamp the positive terminal clamp (red) of the
charger to the chassis or engine block, away from the battery.
Do not connect to the carburettor, fuel lines or sheet metal
body parts.
3. Connect the power cable of the battery charger to the mains.
4. When disconnecting, disconnect from the mains first, remove
the grounded clamp and then remove the clamp connected to
the battery.
