Operating Instructions
Please read these instructions before use
The new GSL Battery Chargers are revolutionary 4 Stage charger conditioners, utilising Switchmode technology and
microprocessor control and designed to charge 12Volt (BC240-1230) or 24Volt (BC240-2418) Lead Acid and Calcium
Batteries. The battery charger provides a safe and fast method of restoring discharged batteries and maintaining
them, via precisely controlled Bulk, Absorption, Float and Pulse stages.
without a battery connected. The chargers are fully protected against overload, short circuit, over temperature,
reverse polarity connection, over voltage and with a bulk charge timeout for additional safety.
The chargers are built in a compact and strong aluminium extrusion which can be easily secured to both vertical and
horizontal surfaces and will be fully operational with voltages as low as 190Vac or as high as 260Vac.
Before starting the charge cycle the battery voltages are evaluated to detect faulty batteries.
BULK MODE – This mode of the battery charger delivers bulk charging current regulated to 18/30 Amps into the
battery being charged. When the battery voltage rises to approx. 14.3V/ 28.6V (15.3V/30.6V for Calcium) and the
battery is approximatly 70% recharged. The charger will switch automatically to Absorption Mode.
ASORPTION MODE – In this mode the battery charger output voltage is maintained at the same level until the
current drops below a controlled threshold. The battery is brought up to a 90% recharge.
FLOAT MODE - The voltage is reduced to 13.5V/27V (14V/28V for Calcium) and maintained at that level with the
charger supplying just enough current to maintain the battery at full capacity.
PULSE MODE – Periodic low current pulse to maintain maximum battery life.
Installation & Safety Precautions:

which may ignite and explode.
c. Never smoke or light cigarettes near a battery.
d. Do not place tools on top of battery or allow tools to fall on battery.
e. Always wear eye protection near a charging battery.
f. Ensure a “well” ventilated area is used when testing or re-charging batteries.
g. Ensure ventilation is adequate and venting holes are not obstructed. Inadequate ventilation may over-heat the
h. The battery charger is intended for indoor use only. Do not expose it to outdoor weather conditions
e.g. rain or dampness.
i. .
Seek medical attention if necessary.
j. 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
Should product require service, return it to place of purchase for warranty advice.
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 approximately 1/5 of C.
For example: if you have a 100Ah battery, the recommended charging current is: 100 / 5 = 20A.
The majority of the battery capacity would normally be charged in 5 hours using a 20 Amp battery charger.
Similarly it would take approximately 10 hours to charge the battery with a 10 Amp battery charger.

Procedures for Charging a Battery:
The chargers are intended for 12V/24V lead acid and Calcium batteries with a capacity ranging from 50AH to 250AH.
DO NOT attempt to recharge non-rechargeable batteries or non lead acid based chemistries.
