4.2 CHARGING BATTERY PACKS
Battery chargers are available from M/A-COM with nominal charge times of one hour. Combinations
include single and multi-position, rapid charge units.
M/A-COM chargers are rapid chargers specifically designed for charging nickel-based battery packs. The
chargers differentiate between NiCd or NiMH battery packs and automatically adjust charging rates.
Refer to the appropriate charger manual for specific operating instructions.
4.2.1 Charging Guidelines
Observe the following guidelines when charging a battery pack:
Avoid high temperature during charging.
Discontinue use if the charger is overheating.
Only charge NiCd or NiMH battery packs using a rapid charger approved for use by M/A-COM.
Do not leave batteries in the charger indefinitely. For best results leave the battery in the charger for
two to six hours after the Green Ready LED comes on. Then place the battery pack into service and
fully discharge (as indicated by the radio low battery warning) before re-charging.
If any faults are encountered while charging the battery pack, consult the charger’s manual to determine
the cause and possible corrective action.
4.3 BATTERY PACK USAGE
NiCd and NiMH batteries vary in capacity and life cycle. NiCd batteries have a longer life cycle than
NiMH batteries whereas NiMH batteries have a larger capacity. Both types of batteries require following
basic usage guidelines in order to increase the battery runtime or shift life.
4.3.1 Usage Guidelines
The following guidelines will help increase the battery runtime or shift life:
Ensure the battery pack is fully discharged (as indicated by the radio low battery warning) before re-
charging.
Periodically condition battery packs, frequency to be determined based on usage patterns (refer to
ECR-7367). If the battery is fully discharged (to radio Low Battery warning) during routine use, the
frequency of conditioning may be extended.
Do not leave NiCd or NiMH batteries in a charger for more than a few days.
