When you plug in and turn on your approved battery charger the battery will charge at 13.8 volts as indicated by the blue “Charging” LED. A red LED will indicate the level of charge. When the blue “Charging” LED extinguishes, the internal battery is fully charged at it’s maximum of 12.5 volts.

Once charged, the battery voltage bar graph indicator shows the remaining battery charge level. As the reader is used and the battery drains, the battery voltage indicator will drop to a lower voltage reading. At about 11.0 volts, the low battery warning will sound and it is advised to plug in an external battery or power supply as soon as possible to keep the reader powered up. At about 10.8 volts, the reader will shutdown to prevent damage to the internal battery.

How long the reader’s battery will last without charging will depend on how hard it is working. If you are using more features, the battery will discharge more quickly. A detailed explanation is provided in Battery Life

The reader must be stored with a fully charged battery. Please charge the reader immediately after using it. This will prolong it’s life, saving you time and stress in the future! As a general rule if you use the reader for 4 hours the reader will require 4 hours to fully recharge.
