Abstract

Battery chargers are designed to recharge bat- teries with a rapid rate of current (1 times battery capacity) followed by much lower trickle charging rate (l/20 times battery capacity-NiH)). When the trickle charging rate of the battery charger is lower than the standby current drain ("on" condition) of the portable radio the battery is discharged by a radio left "on" in the battery charger. If the portable is in the charger over a long enough period such as a weekend, this could result in a completely discharged battery coming out of the battery charger on Mon- day morning. This is a condition that exists in the held today for Jedi products and has been a cus- tomer complaint.
