• High-density (dark) printing discharges the battery faster than low-density printing. Adjust the print density setting in the Device Settings. For more information, see Related Topics.
• The battery charging must take place in an environment with a temperature between 0°C and 40°C, otherwise the battery will not be charged. If the charging stops because the environment temperature is too low or too high, place the printer in an environment with a temperature between 0°C and 40°C and try charging again.
• The recommended charging temperature range for the battery is from 5°C to 35°C.
• If you use the printer when both the battery is installed and the AC Adapter or Car Adapter is connected, charging may stop even if the battery is not fully charged.

To ensure the highest performance and longest life from the battery:

• Do not use or store the battery in a location exposed to extreme high or low temperatures as it may deteriorate more quickly.
• Remove the battery when storing the printer for long periods of time.
• Store batteries with less than a 50% charge in a cool dry place and out of direct sunlight.
• Recharge the battery every six months if it is stored for long periods of time.
• It is normal and safe for the printer to become warm while charging. Disconnect the charger and stop using the printer if it becomes hot to the touch.
• When the printer is turned on, the battery health status appears on the LCD.

  For the battery health level indication, see Related Topics.

To stop the battery charging, disconnect the printer from the computer or power source.
