WARNING! This Battery Pack contains potentially hazardous voltages. Do
not attempt to disassemble the Battery Pack beyond the battery replacement
procedure. This Battery Pack contains no user serviceable parts.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful
to the skin and eyes and may be toxic.
CAUTION: Do not dispose of batteries in a fire. The batteries may explode.
The batteries in this Battery Pack are recyclable. Dispose of the batteries
properly. The batteries contain lead and pose a hazard to the environment
and human health if not disposed of properly. Refer to local codes for proper
disposal requirements or return the battery to the supplier.
CAUTION: The battery system can present a risk of electrical shock. These
batteries produce sufficient current to burn wire or tools very rapidly, produc-
ing molten metal. Observe these precautions when replacing the batteries:
1. Remove watches, rings, or other metal objects.
2. Use hand tools with insulated handles.
3. Wear protective eye gear (goggles), rubber gloves and boots.
4. Do not lay tools or other metal parts on top of batteries.
5. Disconnect the charging source prior to connecting or disconnecting the
battery terminals.
6. Determine if the battery is inadvertently grounded. If the battery is, remove
the source of the grounding. Contact with any part of a grounded battery
can result in an electrical shock. The likelihood of such shock will be redu-
ced, if such grounds are removed during installation and maintenance.
Please read all of the WARNINGS and CAUTIONS before attempting to ser-
vice the batteries. Typical battery life is 3 to 5 years. Environmental factors
do affect battery life. High temperatures, poor utility power, and frequent,
short duration discharges have a negative impact on battery life.
CAUTION: Replace batteries with the same number and type as originally
installed in the Battery Pack. These batteries have pressure operated vents.
These Battery Packs contain sealed non-spillable maintenance-free lead acid
batteries.
