Automatic Battery Charger

Operating Instructions

Please read these instructions before use

The GSL Battery Charger is a sophisticated 2 Mode Boost and Float Charge Type, utilising Switchmode technology
and designed to charge 12 Volt Lead Acid Batteries. As a Lead Acid Battery Charger, the unit provides a safe method
of restoring discharged batteries, via Boost and Float Mode circuitry.
Boost Mode – In this mode the battery charger delivers bulk charging current up to 10 Amps into the battery.
When the battery voltage rises to approximately 13.8V, and the battery is 90% re-charged. The charger will
switch automatically to Float Mode.
Float Mode – In this mode the battery charger output current is reduced to approximately 2A and the cooling fan is
turned off. The battery is brought up to a 100% recharge and is constantly maintained at that level with the charger
supplying just enough current to maintain the battery at full capacity.

Color Condition

Red - Boost The battery voltage is relatively low, the unit is charging at almost full output

current and the fan is on.

Orange- Float Battery charger in the float mode, charge current is below 2A and the fan is off.

Green - Power Indicates that the AC power is within acceptable levels.

Installation & Safety Precautions:

1. This appliance is not meant for use by young children.

2. Young children should be supervised to ensure that they do not play with the appliance.

3. During charging process, do not use a naked flame near a battery, due to gases emitted from the battery

,

which may ignite and explode.

4. Never smoke or light cigarettes near a battery.

5. Do not place tools on top of battery or allow tools to fall on battery.

6. Always wear eye protection near a charging battery.

7. Ensure a “well” ventilated area is used when testing or re-charging batteries.

8. Ensure ventilation is adequate and venting holes are not obstructed. Inadequate ventilation may over-heat the

unit and cause inefficient operation.

9. The battery charger is intended for internal use only. Do not expose it to outdoor weather conditions e.g. rain
or dampness.

10. If skin or clothing comes into contact with acid, flush the area(s) with water immediately.
Seek medical attention if necessary.

11. The battery charger contains hazardous voltages. There are no user serviceable components inside. If the AC
supply cord is damaged, in order to avoid a hazard it must be replaced by the manufacturer or its service

agent or a similarly qualified person. Should product require service, return it to place of purchase .

Battery Charging Times:

The question of “how long will my battery take to re-charge” is always asked. Firstly, the charge rate (CR) of a
battery is rated in Amps and the battery capacity (C) in Amp Hours. The battery manufacturer for each battery type
normally states this CR. As a rule of thumb, a lead acid battery generally should be charged under 1/5 of C.
For example if you have a 50Ah battery, the recommended max. charging current is : 50 / 5 = 10A.
The majority of the battery capacity would normally be charged in 5 hours using a 10 Amp battery charger.
Similarly it would take approximately 10 hours to charge a battery with a 5 Amp battery charger.

*Please note the figures quoted above could vary depending on the battery condition.

Procedures for Charging a Discharged Battery:

The charger is intended for 12V lead acid batteries with a capacity ranging from 10AH to 50AH.
To avoid reverse polarity connection, the charger output leads are fitted with coloured battery clips for

easy identification: Red for (+) Positive pole and Black for (–) Negative pole.

Prolonged output short circuit (above 20 seconds) or polarity reversal may require replacement of the
output lead mounted 15A 12V output blade fuse.

1. Before connecting charger to battery, ensure that 240VAC power is switched off.

2. Disconnect all battery cables i.e. vehicle battery cables etc.

3. Remove cell caps from battery and check electrolyte levels in each cell with hydrometer. Ensure that

electrolyte levels cover all plates in each cell completely.

4. Connect (+) positive and (–) negative clips to the respective battery terminals, ensuring a firm connection.

5. Connect battery charger to 240VAC power point and switch ON.

6. During the charging process the battery may be bubbling and emitting gases. This is quite normal.

7. When the battery is fully charged, switch 240VAC power OFF and remove the charger cables from the battery.
