Systems and Methods for Operating a Downhole Battery

A method comprising:

• receiving, via a battery controller of a battery system, a threshold temperature value;
• receiving, via the battery controller, temperature data from one or more sensors;
• and
• enabling, via the battery controller, the battery system to provide power to a release device in a wellbore upon the temperature data exceeding the threshold temperature value.

A system comprising:

• a battery system comprising a battery controller configured to:
• receive a timer value;
• enable the battery system to provide power to a release device in a wellbore upon receiving the timer value;
• and
• receive an updated timer value, wherein the updated timer value changes the timer value, and the battery system continues to provide power to the release device at least until the updated timer value expires.
