Battery-specific adjustments to maximum battery voltage

A method comprising:

• determining, by a device comprising a battery, a first value indicative of a first length of time during which the battery outputted a first voltage and was at a first temperature, wherein the first voltage is an average voltage during the first length of time and the first temperature is an average temperature during the first length of time;
• determining a second value indicative of a second length of time during which the battery outputted a second voltage and was at a second temperature, wherein the second voltage is an average voltage during the second length of time and the second temperature is an average temperature during the second length of time;
• determining that a first sum of the first value and the second value is equal to or greater than a first threshold value;
• and
• changing the first maximum output voltage value to a second maximum output voltage value that is lower than the first maximum output voltage value.

A device comprising:

• a battery having an associated first maximum output voltage value;
• memory configured to store computer-executable instructions;
• and
• at least one computer processor configured to access the memory and execute the computer-executable instructions to:
• determine a first value indicative of a first length of time during which the battery outputted a first average voltage and was at a first average temperature;
• determine a second value indicative of a second length of time during which the battery outputted a second average voltage and was at a second average temperature;
• determine, based at least in part on the first length of time, a third value indicative of a third length of time during which an average voltage output of the battery will be substantially the first average voltage and an average temperature of the battery will be substantially the first average temperature;
• determine that a second sum of the first value, the second value, and the third value satisfies a second threshold;
• and
• determine a third maximum voltage value that is lower than the second maximum voltage value.
