Abstract: Systems, methods, and computer-readable media are disclosed for battery-specific adjustments to maximum battery voltage. In one embodiment, an example device may include a battery, at least one memory that stores computer-executable instructions, and at least one processor. The device may be configured to determine a first value indicative of a first length of time the battery was at a first voltage and a first temperature, determine a second value indicative of a second length of time the battery was at a second voltage and a second temperature, determine that a sum of the first value and the second value satisfies a first threshold, and cause a maximum output voltage value to be reduced from a first maximum output voltage value to a second maximum output voltage value.

Abstract: Systems, methods, and computer-readable media are disclosed for dynamic adjustments to battery parameters using battery metrics. The device may be configured to determine a first value indicative of a battery voltage output during a first time interval, determine a second value indicative of a temperature during the first time interval, and determine a first acceleration factor for the battery during the first time interval based at least in part on the first value and the second value. The device may determine an adjusted number of charge cycles completed during the first time interval using the first acceleration factor, determine a total adjusted number of charge cycles of the battery, determine that the total adjusted number of charge cycles is equal to or greater than a first threshold, and cause the first maximum output voltage value to be reduced.
