1. An apparatus, comprising:
- a battery; and
one or more processors programmed to;
monitor a voltage level of the battery;
wait until the monitored voltage level of the battery reaches a pre-specified voltage value (VM);
incident to the monitored voltage level of the battery reaching VM, set a charging current to a pre-set maximum charging current (IM);
after the charging current is set to IM, check a temperature of the battery against a pre-set range of temperatures;
incident to the temperature of the battery being within the pre-set range of temperatures, monitoring an impedance of the battery;
assign a weight to the monitored impedance of the battery based on the monitored voltage level of the battery;
select a charging profile for the battery based, at least in part, on the weight assigned to the monitored impedance of the battery based on the monitored voltage level of the battery; and
charge the battery according to the selected charging profile.
