PROBLEM TO BE SOLVED: To provide a battery-powered meter that can be rapid-charged without a significant temperature rise, and manage it to minimize power consumption while maintaining an accurate assessment of a state of battery charge during periods of non-use.SOLUTION: A charger component is operably associated with a meter and executes a rapid charge algorithm for a rechargeable battery 802. The algorithm includes monitoring for a connection to an external power source and implementing a charging routine of a battery at a first charge rate and then at a second charge rate. The second charge rate is lower than the first charge rate. The meter can also include a power switch 814 for controlling a current flow to a battery fuel gauge 803. The power switch is open when the meter enters into a sleep mode. A state of battery charge is determined after the meter exits the sleep mode. |
