It's best to replace the battery when it no longer provides acceptable
performance. It can be recharged hundreds of times before it needs
replacing.
Don't store the battery in high temperature areas for long periods of
time. It's best to follow these storage rules:
Less than one month:
-4° F to 140° F (-20° C to 60° C)
More than one month:
-4° F to 113° F (-20° C to 45° C)
Disposal of Lithium Ion (Li-Ion) Batteries

Radio Frequency (RF) Energy

Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When it's turned
on, it receives and transmits radio frequency (RF) signals. When you use
your phone, the system handling your call controls the power level. This
power can range from 0.006 watt to 0.2 watt in digital mode.
Knowing Radio Frequency Safety
The design of your phone complies with updated NCRP standards
described below.
In 1991–92, the Institute of Electrical and Electronics Engineers (IEEE)
and the American National Standards Institute (ANSI) joined in updating
ANSI's 1982 standard for safety levels with respect to human exposure
to RF signals. More than 120 scientists, engineers and physicians from
universities, government health agencies and industries developed this
updated standard after reviewing the available body of research. In
1993, the Federal Communications Commission (FCC) adopted this
updated standard in a regulation. In August 1996, the FCC adopted
hybrid standard consisting of the existing ANSI/IEEE standard and the
guidelines published by the National Council of Radiation Protection and
Measurements (NCRP).
