The method also includes enabling, via the battery controller, the battery system to provide power to a release device in a wellbore upon receiving the timer value. Moreover, the method includes receiving, via the battery controller, an updated timer value, and 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. ## Claims ### Claim 1 A method comprising: receiving, via a battery controller of a battery system, a timer value; enabling, via the battery controller, the battery system to provide power to a release device in a wellbore upon receiving the timer value; and receiving, via the battery controller, 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. ### Claim 2 (depends on 1) The method of claim 1, comprising operating, via the battery controller, the release device upon the timer value expiring or the updated timer value expiring. ### Claim 3 (depends on 2) The method of claim 2, wherein operating the release device comprises operating a motor of the release device to cause the release device to release a downhole tool in the wellbore. ### Claim 4 (depends on 2) The method of claim 2, wherein the battery system is the sole source of power for operating the release device. ### Claim 5 (depends on 1) The method of claim 1, comprising: receiving, via the battery controller, 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 the release device in the wellbore upon the temperature data exceeding the threshold temperature value. ### Claim 6 (depends on 5) The method of claim 5, comprising disabling, via the battery controller, the battery system if the temperature data is below the threshold temperature value. ### Claim 7 (depends on 5) The method of claim 5, comprising enabling, via the battery controller, the battery system to provide power to a release device in a wellbore upon receiving the timer value or upon the temperature data exceeding the threshold temperature value. ### Claim 8 (depends on 5) The method of claim 5, comprising enabling, via the battery controller, the battery system to provide power to a release device in a wellbore upon receiving the timer value and upon the temperature data exceeding the threshold temperature value. ### Claim 9 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. ### Claim 10 (depends on 9) The method of claim 9, comprising disabling, via the battery controller, the battery system if the temperature data is below the threshold temperature value. ### Claim 11 (depends on 9) The method of claim 9 comprising: receiving, via the battery controller, a timer value; enabling, via the battery controller, the battery system to provide power to the release device in a wellbore upon receiving the timer value; and receiving, via the battery controller, 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. ### Claim 12 (depends on 11) The method of claim 11, comprising operating, via the battery controller, the release device upon the timer value expiring or the updated timer value expiring. ### Claim 13 (depends on 12) The method of claim 12, wherein operating the release device comprises operating a motor of the release device to cause the release device to release a downhole tool in the wellbore. ### Claim 14 (depends on 12) The method of claim 12, wherein the battery system is the sole source of power for operating the release device. ### Claim 15 (depends on 11) The method of claim 11, comprising enabling, via the battery controller, the battery system to provide power to a release device in a wellbore upon receiving the timer value or upon the temperature data exceeding the threshold temperature value. ### Claim 16 (depends on 11) The method of claim 11, comprising enabling, via the battery controller, the battery system to provide power to a release device in a wellbore upon receiving the timer value and upon the temperature data exceeding the threshold temperature value. ### Claim 17 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. ### Claim 18 (depends on 17) The system of claim 17, wherein the controller is configured to operate a motor of the release device to cause the release device to release a downhole tool in the wellbore upon the timer value expiring or the updated timer value expiring. ### Claim 19 (depends on 18) The system of claim 18, wherein the battery system is the sole source of power for operating the release device. ### Claim 20 (depends on 17) The method of claim 17, wherein the controller is configured to: receive a threshold temperature value; receive temperature data from one or more sensors; and enable the battery system to provide power to the release device in the wellbore upon the temperature data exceeding the threshold temperature value.
