# Power supply and battery

TX T\&H MINI AMB: power supply and battery

The TX T\&H MINI AMB offers a power supply mode on **Battery**; use the supplied battery for optimal battery life. To start the sensor, simply remove the insulating tab.

To change the battery of the TX T\&H MINI AMB, you must first remove the sensor from its mount and clear access to the battery.

{% endcolumns %}

{% hint style="danger" %}
Don't forget to remove the screw, otherwise the sensor cannot be opened!
{% endhint %}

The TX T\&H MINI AMB uses a 2/3AA 3.6 V lithium battery.

If your sensor was still operating but with a weak battery, it will continue to operate without any action from you.

If, on the contrary, the sensor had no battery left, it will then start up again.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://enless.gitbook.io/centre-aide/guides-installation/documentation-en/sensors/editor/use/power-supply-and-battery.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
