1.0Batteries
A new range of batteries have been developed for the new GP Series of Professional Family Portable Radios, this includes all GP300, GP600 and GP1200 Series radios.
Three different types of battery chemistry are now available to provide the most effective solution. Each has been designed to optimise a different set of the important parameters; size, weight and service life.
These are:
Lithium Ion (LiIon).
Nickel Metal Hydride (NiMH).
Nickel Cadmium (NiCd).
In order to ensure that these battery types, each based upon a different chemical technology, are correctly and safely charged and function properly, the Professional Series batteries contain a small Integrated Circuit that identifies its key parameters to the radio and to the charger.
1.1Lithium Ion (LiIon)
These batteries utilise the most modern chemistry, provide the highest power at the lowest weight and contain a built in protection circuit. However, these batteries are not recommended for use at the extremes of temperature due to a marked decrease in capacity.
For safety reasons these batteries must only be charged in a ‘smart’ charger designed for the specific cell characteristics. All Motorola Professional Series radios are suitable for the LiIon batteries.
Advantages
Lightest weight of all batteries.
State of the art chemistry.
No memory effect.
Disadvantages
Longer charge times.
