Battery Life
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 discharges 100% 
several times a day, will last 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, will last even longer.
Charging the Battery 
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. 
Motorola-authorized battery chargers may not charge batteries other 
than the ones listed on page 114.
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.
