Abstract
A method (600, 700, 800) for charging a battery (102) comprises obtaining, by charging circuitry (120), an open circuitry voltage of the battery prior to a charging session. The charging circuitry is in electrical communication with a power source (110) and the battery. The method also comprises initiating the charging session to charge the battery at a constant charge current-constant charge voltage with power provided from the power source and obtaining an ambient temperature (T) measured by a temperature sensor (160) in communication with the charging circuitry. The method also comprises obtaining a charge termination time (tt) based on the ambient temperature and terminating the charging session when the charge termination time is reached.
