IMPORTANT NOTE ON BATTERIES:
DANGER: Batteries are electrically live at all times, take great care never to short circuit the battery
terminals.
WARNING:
Batteries are often heavy, take great care when lifting and transporting batteries. For
weights above 24kg, lifting aids should be used.
WARNING:
Do not attempt to remove the battery lid or tamper with the battery internal workings.
Electrolyte is a highly corrosive substance and presents signifi cant danger to yourself and to anything
else it touches. In case of accidental skin or eye contact, fl ush the aff ected area with plenty of clean,
fresh water and seek immediate medical attention.
VRLA batteries are “low maintenance” requiring no electrolyte top-up or measurement of specifi c
gravity. Always refer to the battery manufacturer’s data.
WARNING: If required, clean the case of the battery with a cloth that has been soaked or dampened
with distilled water. Do not use organic solvents (such as petrol, paint thinners, benzene or mineral
spirits) and other materials can substantially weaken the case.
WARNING:
Avoid charging the batteries in fl oat/standby applications outside of the range quoted by
the battery manufacturer.
WARNING:
Do not incinerate batteries. If placed in a fi re, the batteries may rupture, with the po-
tential to release hazardous gases and electrolyte. VRLA batteries contain substances harmful to the
environment. Exhausted batteries must be recycled. Return them to the battery manufacturer or take
them to your Council tip for appropriate disposal.
