THE BCDC1240-LV

The BCDC1240-LV In-vehicle Battery Charger features technology designed to charge your 
batteries to 100%, regardless of their type or size. By providing a unique charging profi le to 
each specifi c battery type, the BCDC1240-LV In-Vehicle Battery Charger is able to achieve and 
maintain an optimal charge in your auxiliary battery, at all times. It is designed to operate with 
variable voltage alternators
The BCDC1240-LV In-vehicle Battery Charger also features a Maximum Power Point Tracking 
(MPPT) solar regulator, allowing you to deliver the maximum amount of power from your solar 
panels to your auxiliary battery.

WARNING & SAFETY INSTRUCTIONS

This appliance is not intended for use by persons (including children) with reduced physical, 
sensory or mental capabilities, or lack of experience and knowledge, unless they are supervised 
or have been instructed on how to use the appliance by a person responsible for their safety.  
Children should be supervised to ensure that they do not play with the appliance.

Do NOT disassemble the BCDC1240-LV - the internal circuitry contains hazardous voltages.  
Attempting to service the unit yourself may result in electric shock or fi re and will void the unit 
warranty.

Do NOT use the BCDC1240-LV to charge non-rechargeable batteries.  Doing so may result in 
harm to the user and/or damage to the BCDC1240-LV.  Only use the BCDC1240-LV for charging 
Standard Lead Acid, Calcium content, Gel & AGM type 12V batteries.

All lead acid batteries produce harmful, explosive gases.  The Battery should be mounted in a well 
ventilated area, as far as possible from any ignition sources.  Do NOT smoke when in the vicinity 
of the battery under charge.

Battery acid is a harmful substance.  Care should be taken when working with lead acid batteries, 
if the acid comes into contact with your eyes or skin, immediately wash the affected area with 
cold running water and seek medical assistance.  Eye protection and gloves should be worn when 
handling lead acid batteries.

The BCDC1240-LV will achieve best results when proper battery maintenance is regularly 
performed.  This includes but is not limited to checking water and specifi c gravity levels of the 
battery.  

Warning! 

  Check the manufacturers data for your battery and ensure that the ‘Absorption’ voltage 

of the profi le you select does not exceed the manufacturers recommended maximum charging 
voltage.  If the ‘Absorption’ voltage for your battery type is too high, please select another charging 
profi le.
