Battery
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 discharged 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 in the user manual. 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.
Battery Charge Status
Your radio can indicate your battery's charge status through:
• LED and sounds
• Conventional fuel gauge symbol on the display
• Smart fuel gauge symbol on the display
LED and Sounds
When your battery is low:
• You see the LED flash red when the PTT button is pressed
• You hear a low-battery "chirp" (short, high-pitched tone)
Conventional Fuel Gauge Symbol
A blinking fuel gauge symbol ( ) is displayed only when the battery voltage drops to low level. In this case, replace the
battery with a fully charged one.
Smart Fuel Gauge Symbol
Consult the Smart Battery manual. All conditions must be met for a battery to be classified as a "Smart Battery." When
your radio has a Smart Battery installed, the fuel gauge symbol is always displayed:
Replace the battery with a fully charged one when the fuel gauge shows the lowest level.
