Battery and Charger
Sprint-approved or LG-approved batteries and accessories can be found at Sprint Stores or through LG,
or call 1-866-866-7509 to order. They‘re also available at www.sprint.com.
Battery Capacity
Your phone is equipped with a Li-Ion battery. It allows you to recharge your battery before it is fully
drained. The battery provides up to 24 hours of continuous digital talk time.
When the battery reaches 2% of its capacity, the battery icon blinks. When there are approximately two
minutes of talk time left, the phone can sound an audible alert and then turn off.
Note: Long backlight settings, searching for service, using vibrate mode, browser use, and other variable
may reduce the battery‘s talk and standby times.
Tip: Watch your phone's battery level indicator and charge the battery before it runs out of power.
Charge the Battery
Keeping track of your battery's charge is important. If your battery level becomes too low, your phone
automatically turns off and you will lose any information you were just working on.
1. Connect the charging adapter and USB cable as shown; the LG logo on the charging adapter
should face toward you.
2. Plug one end of the USB cable into the phone's Charger/Accessory Port and the other end into
an electrical outlet. The charge time varies depending upon the battery level.
Battery Temperature Protection
Though extremely rare, if the battery becomes overheated, the phone will automatically turn off.
Charge with a PC Using a USB Cable
You can use your computer to charge your phone. To be able to charge with the USB cable, you need to
install the necessary USB drivers on your computer first. Connect one end of the USB cable to the
Charger/Accessory Port on your phone and connect the other end to a USB port on your computer. It is
best to use the rear USB port when connecting to a desktop computer. The USB hub should be powered
by an external power source.
Note: Low-power USB ports are not supported, such as the USB port on your keyboard or bus-powered
USB hub.
The LG USB Driver is downloadable from the following site: http://www.lg.com/us/ > Select SUPPORT. In
