Abstract
A thermal battery positioned in a wellbore can be force activated by a device. The device can include a body coupled to a thermal battery positioned in a wellbore. The body can include a piston retained at a first position in an inner area of the body. The piston can move from the first position to a second position in response to a force applied to the body. The thermal battery can be activated by moving the piston to the second position.
Claims18
A device comprising:
- a body coupleable to a thermal battery and positionable in a wellbore, the body comprising a piston retained at a first position in an inner area of the body, the piston being moveable from the first position to a second position in response to a force applied to the body and for activating the thermal battery by moving to the second position, wherein the thermal battery is a first thermal battery, and wherein the body is removable from the wellbore separate from the first thermal battery and reusable with a second thermal battery.
A system comprising:
- a tool positionable in a wellbore;
- a thermal battery positionable in the wellbore and communicatively coupleable to the tool for providing power to the tool in response to being heated above a threshold temperature;
- and
- a body positionable in the wellbore and coupleable to the thermal battery for responding to a force by heating the thermal battery above the threshold temperature, and wherein the thermal battery is a first thermal battery, and wherein the body is removable from the wellbore separate from the first thermal battery and reusable with a second thermal battery.

A method comprising:
- moving a piston retained in a body positioned in a wellbore from a first position in an inner area of the body to a second position in the inner area of the body in response to a force being applied to the piston;
- generating an electrical signal by moving a magnet coupled to the piston through a coil coupled to the body as a result of the piston moving to the second position;
- igniting pyrotechnics coupled to a thermal battery using the electrical signal;
- heating a thermal battery positioned in the wellbore with the pyrotechnics based on the piston moving to the second position;
- and
- activating the thermal battery coupled to the body based on heating the thermal battery above a threshold temperature.
