Safety Warnings When Charging the Battery
WARNING
1. Be sure to follow the rules listed below while charging the battery. Failure to do so may cause the battery to
become hot, rupture, or ignite and cause serious injury.
• When charging the battery, either use a specified battery charger or otherwise ensure that the battery
charging conditions specified by Polycom are met.
• Do not attach the batteries to a power supply plug or directly to a car’s cigarette lighter.
• Do not place the batteries in or near fire, or into direct sunlight. When the battery becomes hot, the built-in
safety equipment is activated, preventing the battery from charging further, and heating the battery can
destroy the safety equipment and can cause additional heating, breaking, or ignition of the battery.
2. Do not continue charging the battery if it does not recharge within the specified charging time. Doing so may
cause the battery to become hot, rupture, or ignite.

aside from the specified device it may damage the performance of the battery or reduce its life expectancy, and if
the device causes an abnormal current to flow, it may cause the battery to become hot, rupture, or ignite and cause
serious injury.
CAUTION
The temperature range over which the battery can be discharged is 10
o
