A three-hour charge provides up to 10 days of use when you type about two hours a day with the backlight on, or about one year without backlight.

To check your keyboard's battery power, turn it on. The battery status light flashes:

• Green — when the battery has an adequate charge
• Red — when the battery is low and needs to be charged



NOTE: If the battery power is critically low, the keyboard backlight is disabled.

To charge the battery:

1. Connect your keyboard to a computer using the Micro-USB charging cable.

   

2. The battery status light will pulse green. You should charge your keyboard for 1 to 3 hours, or until the battery status light turns off.

   NOTE: You can use your keyboard while it charges.
