CARE OF RECHARGEABLE NI-CAD BATTERIES
Always follow the battery manufacturers recommendations for charging
and disposing of ni-cad batteries.
The following is meant as general information regarding ni-cad batteries.
1. Occasionally allow the batteries to fully discharge before recharging. Full discharge
will be indicated by the low battery indicator coming on during receive operation.
2. Always allow the battery to fully charge before using.
3. The above will prevent the batteries from developing “memory” which effectively
reduces their capacity.
4. It is better to store ni-cad batteries that are discharged rather than charged.
