Q. How do I know if the battery is fully charged?
A. The % charge of battery value on the lower right hand side of the main data screen will read 100%. Refer to
page 7.
Q. I have installed the battery correctly but the LCD screen reads ‘Alarm - open circuit’, what is wrong?
A. The battery is faulty or the 10A main fuse is blown. Check battery cables are firmly tightened to battery
terminals.
Q. How can I tell what stage the charger is in?
A. The battery charging cycle is indicated on the lower left hand side of the main data screen. Refer to page 9.
Q. What does Ah mean?
A. Ah is an abbreviation of Amp Hour and is a unit of electrical charge which refers to the battery’s capacity. A
power source rated at one amp hour can deliver one amp continuously for one hour or two amps for half an
hour or sixty amps for one minute etc.
Q. What type of batteries will the Battery Box charge?
A. The Battery Box can charge Lithium-Ion Phosphate batteries and most types of rechargeable 12V Wet Cell
batteries from 60Ah capacity up to 140Ah. There are four main types of 12V conventional Wet Cell batteries
- conventional Lead Acid, Calcium, AGM and Gel. The Battery Box can charge both cold cranking type car
batteries and deep cycle batteries.
Q. How do I know which battery type and Ah rating to select?
A. Normally the battery type and Ah rating is marked on the battery by the manufacturer. If you are not sure
contact your battery retailer. It is very important that the correct battery type is selected since the charger
uses a different charge technique for each battery type.
Q. Can I charge the battery using the external terminals or accessory sockets?
A. Yes you can as long as the main isolator switch is in the ‘on’ position. This type of charging is not
controlled by the on-board microprocessor since the charge current will flow direct to the battery via
the main isolator switch. If an external voltage regulator is not used there is a risk of overcharging and
damaging the battery. Please also consider the accessory sockets are fused at 10A so a current flow higher
than this will blow the fuse.
Q. Can I leave the Battery Box continually plugged in?
A. Yes the Battery Box will go into float cycle.
Q. My AC adaptor gets hot when charging, is that okay?
A. Yes that is normal, it can reach 75°C. Ensure you provide adequate ventilation when charging.
Q. Can I charge the battery and power a device at the same time?
A. Yes, the Battery Box is designed to do this.
Q. Why doesn’t my Battery Box go into charge cycle?
A. AC adaptor could be blown and needs replacing.
