  "textContent": "A power tool battery charger includes a housing, at least one charging circuit coupled to the housing, and an electronic controller coupled to the housing. The electronic controller is configured to receive rental data from a battery pack. The rental data indicate a rental policy associated with the battery pack. A rental condition is determined based on the rental data, where the rental condition indicates conditions for charging the battery pack according to the rental policy. Charger operation data are generated by the electronic controller based on the determined rental condition, and can include a charging rate, charging target, and/or time indication for when to adjust the charging rate and/or charging target of the at least one charging circuit. A machine learning or artificial intelligence controller can also be used when generating the charger operation data. The at least one charging circuit is then operated based on the charger operation data.",
