FREQUENTLY ASKED QUESTIONS
Q. How do I know if the battery is charged
A. The charger's FULLY CHARGED LED will illuminate (solid). Alternatively use
a Battery. Hydrometer A reading of 1.250 or more in each cell indicates a fully
charged battery.
Q. I have connected the charger properly but the 'CHARGING LED'
does not come on
A. In some cases batteries can be flattened to the point where they have very
little or no voltage. This can occur if a small amount of power is used for a long
time, for example a map reading light is left on for a week or more. 7-Stage
chargers are designed to charge from as little as 12V charger 2.0 Volts and 24V
charger 4.0 Volts. If the voltage is lower than 2.0 Volts and 4.0 Volts use a pair of
booster cables to connect between two batteries to provide more than 2.0 Volts
and 4.0 Volts to the battery being charged. The charger can then start to charge
the battery and the booster cables can be removed.
Q. Can I use the charger as a power supply?
A. 7-Stage chargers are designed to only supply power to the battery clips when
they are connected correctly to a battery. This is to prevent sparks during
connection to the battery or if connected incorrectly by mistake. This safety
feature prevents the charger from being used as a 'Power Supply'. No Voltage
will be present at the clips until connected to the battery.
Q. How can I know what stage the battery charger is in?
A. Below are the conditions that are displayed by the LEDs for each of the
charge stages.
