IMPORTANT: DO NOT STORE A BATTERY IN THE CHARGER.
• After charging, unplug the battery charger and remove the battery.
• Storing a battery in the charger diminishes the charged state of the bat-
tery over time and may permanently reduce the capacity of the battery.
Battery handling and precautions
• The battery does not have to be completely discharged in order to charge it. You
can charge the battery at any time.
• Never leave the battery in a discharged state. Charge after use and before storage.
• Avoid extreme temperatures when charging the battery. Battery charging should
occur within the temperature range of 32°F (0°C) to 95°F (35°C).
• A fully charged battery provides approximately 25 hours of use. Replace the battery
when it no longer provides adequate power after charging. To order a replacement
battery, see "Troubleshooting" on page 10.
• Keep the terminals on the battery, in the charger, and in the right earcup of the
headphones clean at all times. Dirty terminals may cause poor electrical connec-
tions and affect performance. For cleaning instructions, see "Cleaning" on page 10.
