Battery management
WARNING!
Batteries contain harmful
chemicals and when used incorrectly, may
cause injury. Observe the guidelines for
battery care, maintenance and safety in this
manual and in the documentation supplied
with your battery.
Battery preservation
In order to extend the operating period between
battery charges, the energizer will begin to
operate at a slow speed and half output energy
when the battery capacity drops below
approximately 40%.
In order to prevent deep discharge and thus
irreversible damage to the battery, the energizer
will stop producing output pulses when the
battery capacity drops below approximately
20%.
Battery charging
WARNING!
- Do not attempt to recharge a
non-rechargeable battery.
- When recharging a battery, ensure that
there is adequate ventilation to allow
gases to disperse.
Regular recharging of the battery is essential.
Use a suitably rated battery charger and refer to
the battery manufacturer's recommendations.
1 Attach the positive (+) battery charger
lead to the positive terminal of the battery,
and the negative (–) battery charger lead
to the negative terminal on the battery.
2 Insert the battery charger's input power
plug into a mains or line socket and turn
on the power supply.
CAUTION!
Over-charging the battery will
reduce its life. Do not exceed the
recommendations of the battery
manufacturer on recharging the battery from
a mains-powered (line-powered) source.
Battery care and maintenance
House the battery in a suitably designed
•
battery box, if the battery is likely to be
exposed to the weather.
When not in use, store the battery fully
•
charged and recharge at regular intervals
(every 8 weeks).
• Recharge a discharged battery as soon as
possible. Batteries should not be left
discharged.
• Inspect the battery regularly to ensure that
the electrolyte level does not fall below
the surface of the battery plates.
Top up the battery using distilled water.
•
Do not overfill. Refer to the battery
manufacturer's recommendations for more
information.
Battery safety
Ensure that the battery is well ventilated
•
when recharging.
• Avoid temperatures greater than 50 °C
(120 °F).
Ensure the battery is not exposed to naked
•
flame or sparks.
