If your internal battery falls low during a call, just snap on

an external battery. The phone automatically starts drawing

from the external battery without dropping the call. The

battery icon starts displaying the charge level of the

external battery.

Follow these guidelines to improve battery performance.

• Do not disassemble or short-circuit the battery.

• Keep the metal contacts at the base of the battery

clean.

• If you have not used an internal or external battery

for more than a month, recharge it before using it.

• Replace the internal battery when it no longer

maintains a charge.

• Do not use any battery in direct sunlight or in places

with high humidity, such as the bathroom.

• Never dispose of any battery in or by a fire. It could

explode.

• Do not charge any battery if the temperature is

below 32ºF (0ºC) or above 122ºF (50ºC).

• Do not store any battery in hot areas for long

periods of time. Follow these storage guidelines:

under 1 month: -4ºF (-20ºC) to 140ºF (60ºC)

over 1 month: -4ºF (-20ºC) to 113ºF (45ºC)
