How should I connect my charger to the battery/vehicle?
The charger should be connected according to the vehicle user manual. If there are no other
recommendations available, connecting the red connector to the positive battery terminal first and
the black connector to the vehicle chassis is common practice for safety reasons.
Which program should I use?
Use programs according to the battery size or type:
MC = 14.4V / 0.8A charge mode for smaller batteries using a low amperage - 0.8A charge rate.
CAR = 14.4V/ Charge mode using the full amperage rating of the charger e.g., MXS 5.0 would use
4.3A for charging
SNOWFLAKE / AGM= 14.7V/ Charge mode using the higher voltage required by some manufacturers.
How will I know that my battery is fully charged?
Depending on the charger as to the LED configuration but if a green LED (Apart from the
power light) is showing then the battery is 100%.
How long does charging take?
It can depend on many factors, for example, the battery size, battery health and state of charge.
There is a table located in the user manual with an estimated number if hours to charge up a battery
to 80%.
Is it dangerous to interrupt the charging process before
my charger has finished?
No.
It is perfectly safe to interrupt the charge process. It is important to let the charger continue the
charging cycle when possible, to fully charge the battery.
Can I use my charger with a vehicle that has an engine
pre-heater?
Yes. It is safe to use the charger with vehicles that use an engine pre-heater without damage to the
vehicle, battery or charger.
