Abstract: A battery charger (10) and associated method for maintaining the charge of a battery (12). The battery charger (10) has a processor (16), power supply (14) and power regulator (15). The battery charger (10) first applies a high current charge to the battery (12), which is terminated when the battery voltage or temperature reaches a defined limit. Then the battery charger (10) applies a low current charge (102) for a set period of time. Next, no charge is applied until the battery (12) cools to an ambient temperature. The ambient temperature is then measured using a thermistor (18) in the battery (12). If the ambient temperature is above a certain threshold no charge is applied for a wait period. If the ambient temperature is below the threshold the low current charge is applied for a the set period of time.

Abstract: An electronic device, such as a radiotelephone, is connectable to a variable-level power source (106). The electronic device includes a rechargeable power source (188) which is repowered responsive to application of operative power generated by the variable-level power source (106). The electronic device provides a constant charge current regulator (168) for converting operative power of a constant voltage into operative power of a constant current to be applied to the rechargeable power source (188) to recharge the rechargeable power source (188). The constant charge current regulator (168) is made of a series connected diode (176) and resistor pair (172). According to a further aspect of the invention, when the rechargeable power source becomes fully recharged, application of the operative power can be reduced by switching (206).

Abstract: A battery charger (10) and associated method for maintaining the charge of a battery (12). The battery charger (10) has a processor (16) and power regulator (15) that apply a low current charge or trickle charge to battery (12). The trickle charge is applied selectively to battery (12) based upon ambient temperature.
