Battery Information

The MTX Series radio receives its power (7.5Vdc) from a rechargeable nickel-cadmium battery as listed in the accessories section. These batteries are a safe, dependable power source for your radio. Proper care of the battery will ensure its effectiveness and allow for peak radio performance.

Recharging Nickel-Cadmium Batteries

Recharge the battery before use to ensure optimum capacity and performance. The battery was designed specifically to be used with a Motorola MTX Series charger. Charging in non-Motorola equipment may lead to battery damage and void the battery warranty.

WARNING: Do not attempt to change or charge the battery in a hazardous atmosphere.

Note: When charging a battery that is attached to the radio, turn the radio off to ensure a full charge.

Charging Temperature

The battery should be at about 77°F (room temperature) whenever possible. Charging a cold battery (below 50° F) may result in leakage of electrolyte and ultimately, in failure of the battery. Charging a hot battery (above 95°F) results in reduced discharge capacity, affecting the performance of the radio. MTX Series rapid-rate battery chargers contain a temperature-sensing circuit to ensure that the battery is charged within these temperature limits.

Short Circuit

Care should be taken to avoid external short circuiting of the battery.

WARNING: A sustained high-rate discharge (for example, a paper clip placed accidentally across the battery contacts) may permanently damage the battery, void the battery warranty, and create a burn or fire hazard.
