Battery Replacement
• Servicing of batteries should be performed or supervised by personnel knowledgeable about batteries and
required precautions.
• CAUTION: Before installing or replacing the batteries, remove conductive jewelry such as chains, wrist
watches, and rings. High energy through conductive materials could cause severe burns.
• CAUTION: Do not dispose of batteries in a fire. The batteries may explode.
• CAUTION: Do not open or mutilate batteries. Released material is harmful to the skin and eyes and may be
toxic.
• CAUTION: Failed batteries can reach temperatures that exceed the burn thresholds for touchable surfaces. .
• CAUTION: A battery can present a risk of electrical shock and high short-circuit current. The following
precautions should be observed when working on batteries:
– Disconnect the charging source prior to connecting or disconnecting battery terminals.
– Do not wear any metal objects including watches and rings.
– Do not lay tools or metal parts on top of batteries.
– Use tools with insulated handles.
– Wear rubber gloves and boots.
– Determine if battery is either intentionally or inadvertently grounded. Contact with any part of a grounded
battery can result in electric shock and burns by high short-circuit current. The risk of such hazards can be
reduced if grounds are removed during installation and maintenance by a skilled person.
