To maximise your battery’s life and performance, make sure you select the appropriate chemistry technology.
ADJUSTABLE CHARGE VOLTAGE
The ENR- Battery Charger’s output voltage (V) can be selected to suit the output voltage of the battery being charged, ie. 12V or 24V.
ADJUSTABLE CHARGE CURRENT
The 25A ENR- Battery Charger’s output current (A) can be selected to suit the capacity of the battery being charged, ie. 25A, 12A, 6A or 2A.
LIQUID CRYSTAL DISPLAY (LCD)-VOLTAGE (V), CURRENT (A) & PERCENTAGE CHARGED (%)
The LCD provides three selectable display outputs. The LED indicators on the fascia highlight the selected characteristic being monitored and displayed.
Four LED status indicators provide a charge status, ie.,
POWER – confirms the unit is connected and receiving a power supply.
CHARGED – when illuminated, confirms the charge cycle is complete and the battery is now fully charged. The LCD will also show FUL for 2 minutes.
CHARGING – when illuminated, confirms the battery charger is charging the battery.
ERROR-will flash if the battery charger does not detect a properly connected battery, or detects an incorrect battery voltage, charging will not commence.
Note-The LCD will show Er1, if the clamps are “shorted”, loose or poorly connected, if the battery voltage is less than 0.5V, or if the battery voltage is >15.5V (for 12V mode) or >31V (for 24V mode).
The LCD will show Er2, if the battery is damaged or unable to be charged.
The LCD will show Er4, if the clamps are connected incorrectly, ie, reverse polarity (+ve clamp to-ve battery terminal and -ve clamp to +ve battery terminal). Note-Batteries with a battery voltage below 10.5V may be permanently damaged – it is recommended that batteries not be discharged to below 10.5V.
This feature provides a stepped or pulsed voltage to help remove the sulphation of plates which can occur when batteries are left discharged for prolonged periods.
Note-If the battery is unable to be recovered (i.e. the sulphation of the plates is too severe), the battery charger will display the error message (Er2).
The latest technology in battery chargers converts 240VAC to DC charging power using electronic components, unlike traditional battery chargers that rely on large heavy transformers. This allows the charger to be lightweight and compact without sacrificing performance. To increase safety, polarity protection prevents the output leads from sparking due to accidental reverse connection or short circuit.
MAXIMISING BATTERY PERFORMANCE
Your battery will perform better when charged using a 9-stage charger, maximising the output from your battery.
MAXIMISE BATTERY LIFE
Batteries used regularly will last longer when charged using a 9-stage charger, saving you money on expensive batteries.
AUTOMATIC MICROPROCESSOR CONTROL
The charger can be left connected to the battery without risk of overcharging. Once the battery is full, the battery charger will automatically monitor the battery and top up the battery when required, ensuring it is always ready for use.
BATTERY CHEMISTRY SELECTION
The 9-stage Repco Battery Charger includes intelligent chemistry technology to provide the most suitable charge profile for the applicable chemistry.
- EFB (Lead Acid) – Bulk/Absorption 14.7V, Recondition 15.8V
Conventional automotive “starting” batteries provide a high current for short periods and are ideally suited to automotive starting applications.
- GEL/AGM – Maximum voltage of 14.2V = GEL and 14.4V = AGM
GEL and absorbed glass mat (AGM) batteries are types of valve regulated lead acid (VRLA) batteries and due to their design can be orientated in any position and exhibit very low gas release during charging. These batteries do not allow the replenishment of electrolyte levels and are sensitive to over-charging, requiring lower charge rates.
- CALCIUM – Bulk Absorption 14.7V, Equalisation/ Recondition 15.8V
Calcium batteries are essentially the same as lead acid batteries however the inclusion of calcium significantly reduces fluid loss, provides much lower self-discharge characteristics, and lowers internal resistance which increases it’s cold cranking current (CCA) performance.
To ensure optimal battery condition and to maintain a maximum state of charge, a special profile is needed to balance cell voltages and/or remove unique sulphation barriers caused when Calcium batteries have a high demand or are left discharged for a number of days,
When the battery has been left unattended for a prolonged period, the sulphation of the plates may be too severe for Stage 2: De-Sulphation cycle to adequately clean the plates. In these instances, the ANALYSIS stage will identify that sulphation of the plates still exists and an additional RECONDITION stage will provide a more concerted effort in an attempt to recover the battery.
For Calcium batteries, the RECONDITION stage will balance any differences in cell voltage, and repair cell stratification of the Calcium battery.
Note-the inclusion of a RECONDITION stage may significantly increase the charge time (up to 48 hours).
LIQUID CRYSTAL DISPLAY
A Liquid Crystal Display (LCD) provides a clear, easy- to-read display.
Repco Battery Chargers provide a low voltage PRE- CHARGE function at a low current to allow the battery cells to equalise.
When the internal temperature of the Repco Battery Charger reaches 50°C, sensors reduce the output current to minimise damage due to overheating.
Note-this feature may cause an increased charge time due interruptions to the charge cycles.
