THE BCDC1225D & BCDC1240D
The BCDC1225D/BCDC1240D Dual Input In-vehicle Battery Chargers feature technology designed
to charge your auxiliary batteries to 100%, regardless of their type or size.
The Dual Input In-vehicle Battery Chargers also feature a Maximum Power Point Tracking (MPPT)
solar regulator. The unit will always take as much power from the Solar input as it can before
supplementing that power, up to the maximum rated output, from Vehicle power input.
The Dual Input In-vehicle Battery Chargers are suitable for all common types of automotive lead
acid batteries and LiFePO
4
lithium type batteries.
WARNING & SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - This manual contains IMPORTANT SAFETY INSTRUCTIONS for the
BCDC1225D/BCDC1240D battery chargers.
DO NOT OPERATE THE BATTERY CHARGER UNLESS YOU HAVE READ AND UNDERSTOOD THIS MANUAL
AND THE CHARGER IS INSTALLED AS PER THESE INSTALLATION INSTRUCTIONS. REDARC RECOMMENDS
THAT THE CHARGER BE INSTALLED BY A SUITABLY QUALIFIED PERSON.
RISK OF EXPLOSIVE GASES:
WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOU
FOLLOW THE INSTRUCTIONS WHEN INSTALLING AND USING THE CHARGER.
1. The Battery Charger should not be used 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 Battery Charger.
2. Do NOT alter or disassemble the Battery Charger under any circumstances. All faulty units must be returned to
REDARC for repair. Incorrect handling or reassembly may result in a risk of electric shock or fi re and may void the
unit warranty.
3. Only use the Battery Charger for charging Standard Automotive Lead Acid, Calcium Content, Gel, AGM, SLI, Deep
Cycle or Lithium Iron Phosphate type 12V batteries.
4. Check the manufacturers data for your battery and ensure that the ‘Maximum’ voltage of the profi le you select
does not exceed the manufacturers recommended maximum charging voltage. If the ‘Maximum’ voltage is too
high for your battery type, please select another charging profi le.
5. When using the Battery Charger to charge a Lithium Iron Phosphate battery, only batteries that feature an inbuilt
battery management system featuring inbuilt under and over voltage protection and cell balancing are suitable.
6. The Battery Charger is not intended to supply power to a low voltage electrical system other than to charge a
battery.
7. Cable and fuse sizes are specifi ed by various codes and standards which depend on the type of vehicle the Battery
Charger is installed into. Selecting the wrong cable or fuse size could result in harm to the installer or user and/or
damage to the Battery Charger or other equipment installed in the system. The installer is responsible for ensuring
that the correct cable and fuse sizes are used when installing this Battery Charger.
8. NEVER smoke or allow a spark or fl ame in vicinity of battery or engine. This may cause the battery to explode.
9. PERSONAL SAFETY PRECAUTIONS
To assist with the safe operation and use of the Battery Charger when connected to the battery:
a) Wear complete eye protection and clothing protection. Avoid touching eyes while working near a battery.
b) If battery acid contacts your skin or clothing, remove the affected clothing and wash the affected area of your skin
immediately with soap and water. If battery acid enters your eye, immediately fl ood the eye with running cold
water for at least 10 minutes and seek medical assistance immediately.

1 PRODUCT FUNCTION
The BCDC1225D/BCDC1240D is a three-stage, 12V DC-DC battery charger that operates
from an alternator input of 12V or 24V and a 12V nominal solar panel input. The input
voltage of the BCDC1225D/BCDC1240D can be above, below or equal to the output
voltage making it ideal for charging an auxiliary 12V battery where the distance from the
main battery may cause a signifi cant voltage drop. The BCDC1225D/BCDC1240D is also
designed to isolate the main battery from the auxiliary battery, to avoid over-discharging
the main battery.
1.1 Display Panel
The front panel features 7 LEDs to display the charge profi le and charge status.

1.2 Charge Profi le LEDs
The Dual Input In-vehicle Battery Chargers feature 4 different charging profi les
designed to suit your battery’s charging requirements. It is recommended to
refer to the charging specifi cations stated by the battery manufacturer and the
installation temperature chart below (Figure 1.2.1) before selecting the profi le for
your installation.

1.3 Charge Status LEDs
The Charge Status LEDs indicate to the user which inputs are available and
what stage of the charge process is currently in.
1.3.1 Solar & Vehicle LEDs
The Solar and Vehicle LEDs will be ON when the input is available and in use
and OFF when the input is not available or not in use.
If both LEDs are ON, both input sources are available and in use.
The Dual Input In-vehicle Battery Charger uses Green Power Priority technology.
This means the unit will always supply as much power as possible from the
Solar input before supplementing this with power from the Vehicle input, to the
maximum output of the unit or required by the battery at the time.
1.3.2 Stage LED
The Stage LED indicates the charge profi le stage. With either A, B or C Profi les
selected the charger will output a 3-Stage Lead Acid type charging profi le with
Boost, Absorption and Float Stages. When the Li Profi le is selected the charger
will output a 2-Stage LiFePO
4
type charging profi le with Constant Current and
Constant Voltage stages.
Figure 1.3.2.1 outlines the LED sequences which indicate these stages and
fi gure 1.3.3.1 explains the Charging Process.
