About the Li-Ion Battery
The RM Series™ radio comes equipped with a
rechargeable Li-Ion battery. This battery should
be charged fully before initial use to ensure
optimum capacity and performance.
Battery life is determined by several factors.
Among the more critical are the regular
overcharge of batteries and the average depth
of discharge with each cycle. Typically, the
greater the overcharge and the deeper the
average discharge, the fewer cycles a battery
will last. For example, a battery which is
overcharged and discharged 100% several
times a day, lasts fewer cycles than a battery
that receives less of an overcharge and is
discharged to 50% per day. Further, a battery
which receives minimal overcharging and
averages only 25% discharge, lasts even
longer.
Motorola batteries are designed specifically to
be used with a Motorola charger and vice
versa. Charging in non-Motorola equipment
may lead to battery damage and void the
battery warranty. The battery should be at
about 77°F (25°C) (room temperature),
whenever possible. Charging a cold battery
(below 50° F [10°C]) may result in leakage of
electrolyte and ultimately in failure of the
battery. Charging a hot battery (above 95°F
[35°C]) results in reduced discharge capacity,
affecting the performance of the radio.
Motorola rapid-rate battery chargers contain a
temperature-sensing circuit to ensure that
batteries are charged within the temperature
limits stated above.
