A method includes receiving, via a battery controller of a battery system, a timer value. 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.

Systems and methods for operating a downhole battery

A system includes a downhole tool having multiple electric leads. The system also includes a release device that includes an outer shell configured to mechanically couple to the downhole tool, and the outer shell is configured to form a cavity that is fluidly separate from wellbore fluids contained within a wellbore while the outer shell is mechanically coupled to the downhole tool. The release device also includes a contact block configured to electrically couple to the multiple electric leads. In addition, the contact block is configured to electrically decouple from the multiple electric leads while the outer shell remains mechanically coupled to the downhole tool. Further, the contact block is configured to remain in the cavity after electrically decoupling from the plurality of electric leads.
