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.
