	About the Li-Ion Battery
	The RM Series radio comes equipped with a
	rechargeable Li-Ion battery. This battery should
	be fully charged before initial use to ensure
RADIO	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.
