1. INTRODUCTION

This series of battery chargers are field proven for charging all types of lead acid batteries including Gel and
AGM. They are ideal for caravan, motor homes. Wheelchair, electric scooter and etc.

Main Features are:

(a) Charging battery with external load connected at the same time.
(b) Lead acid wet/gel cell selector switch for optimum Boost and Float Charge Voltages based on

battery type.

(c) Fully Automatic, battery can be left on charge unattended all the time.
(d) Temperature compensation adjusts charging voltage based on battery temperature via remote

(optional accessory).

2. SAFETY PRECAUTIONS

1. Do not smoke, strike a match, place metal tools on battery or cause a spark in the vicinity of the

battery. When removing battery cables, remove ground cable first.

2. Do not charge the battery on boats. Remove the battery and charge on shore.

3. Lead Acid Battery contains highly corrosive sulphuric acid. Avoid contact with eyes, skin and

clothing while working with battery.

4. Working in Vicinity of a Lead Acid Battery is dangerous. Batteries generate EXPLOSIVE gases
during normal operation. Provide ventilation to outdoors from the highest point of the battery
compartment.

5. Be extra cautious to reduce the possibility of dropping a metal tool onto batteries. It might spark or
short circuit batteries or other electrical parts that may cause explosion. Cover wrench handles
with plastic tape or vinyl dip coating material.

6. Do not expose charger to rain, snow and wet conditions.

7. Use charger only for Lead-Acid Batteries.

8. Check that the model number of the charger matches the voltage and capacity of the battery.

Model no. Battery Voltage Maximum Charging Current Recommended Battery Capacity

SBC-8112 12V 10A 50-120 AH
SBC-8125 12V 20A 120-200 AH
SBC-8215 24V 10A 50-120 AH

( Table 1 )

9. Please refer to battery manufacturer’s specific recommended values for setting Boost(Bulk)
charging voltage.

10. Before using the battery charger, read all the instructions and cautionary markings on the battery
charger and the batteries

11. Do not attempt to repair the battery charger. Incorrect re-assembly may result in a risk of electric
shock or fire.

12. To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or
cleaning Turning off controls will not reduce this risk.
