Batteries

A new range of batteries have been speciÞcally developed for the new P Series of Entry Level
Professional radios. They are available with 2 types of battery chemistry:

Nickel Metal Hydride (NiMH)

Nickel Cadmium (NiCd).

Both battery technologies meet various operational requirements depending on the application and
use of the radio. The genuine Motorola batteries ensure that the quality, reliability and performance
of the radio are not compromised.
1.1 Nickel Metal Hydride (NiMH)
This technology operates similar to and provides a similar capacity to Nickel Cadmium batteries.
Advantages
Lighter weight than comparable Nickel Cadmium batteries.
Less prone to memory effect than Nickel Cadmium.
Fewer toxic metals Ð environmentally friendly.
Disadvantages
Self discharges at approximately 30% per month when stored.
Nickel Metal Hydride will not operate at such low temperatures as Nickel Cadmium.
1.2 Nickel Cadmium (NiCd)
This well proven chemistry provides the best performance at extreme temperatures but suffer from
memory effect and provides the lowest power to weight ratio of the two available chemistries.
Advantages
High number of charge / discharge cycles.
Good performance at low temperatures.
Easy to recharge after prolonged storage.
Capable of sustained high rate of charge and discharge.
Disadvantages
Memory effect will develop if battery is not fully discharged at each cycle.
Battery does not performed well if it is left in the charger and is only used for brief periods of
time.
Must be recycled since Cadmium is toxic.
