THE BCDC1212T

The BCDC1212T In-vehicle Battery Charger features technology designed to charge your auxiliary 
batteries to 100%, regardless of their type or size.

The In-vehicle Battery Charger is suitable for all common types of automotive lead acid batteries and 
LiFePO

4

 lithium type batteries.

WARNING AND SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS - THIS MANUAL CONTAINS 

IMPORTANT SAFETY INSTRUCTIONS FOR THE BCDC1212T 

BATTERY CHARGER.
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.

WARNING

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.

CAUTION

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 fire and may void the unit 

warranty.

3.  Only use the Battery Charger for charging Standard 

Automotive Lead Acid, Calcium Content, Gel, AGM, SLI 

(Starting Lighting Ignition), Deep Cycle or Lithium Iron 

Phosphate (LiFePO

4

) type 12 V batteries.

4.  Check the manufacturer’s data for your battery and ensure 

that the ‘Maximum’ voltage of the profile you select does  

not exceed the manufacturer’s recommended maximum 

charging voltage. If the ‘Maximum’ voltage is too high for 

your battery type, please select another charging profile.

5.  Check the manufacturer’s data for your battery and ensure 

that the ‘Continuous Current Rating’ of the charger does 

not exceed the manufacturer’s recommended maximum 

charging current.

6.  When using the Battery Charger to charge a Lithium Iron 

Phosphate (LiFePO

4

) battery, only batteries that feature an 

inbuilt battery management system featuring inbuilt under 

and over voltage protection and cell balancing are suitable.

7.  The Battery Charger is not intended to supply power to a low 

voltage electrical system other than to charge a battery.

8.  Cable and fuse sizes are specified 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.

9.  NEVER smoke or allow a spark or flame in the vicinity of 

battery or engine. This may cause the battery to explode.

10. In applications where the BCDC1212T draws power through 

the vehicle’s and trailer’s towing harnesses and connectors, 

the harnesses wiring gauge, connectors and fuse current 

ratings and fuse type should be checked by a suitably 

qualified person to ensure that it is adequately rated for 

safe and reliable operation and that the vehicle’s fuse is 

appropriately rated and located to protect the wiring in the 

event of a fault, including short circuits.

PERSONAL SAFETY PRECAUTIONS

11. To assist with the safe operation and use of the Battery 

Charger when connected to the battery:

•  Wear complete eye protection and clothing protection. 

Avoid touching eyes while working near a battery.

•  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 flood the eye with running cold 

water for at least 10 minutes and seek medical assistance 

immediately.
