# Power supply and battery

The TX T\&H AMB offers two power supply modes:

* Mode **Battery** : Use the supplied battery for optimal battery life. To activate the sensor, simply remove the insulating tab.
* Mode **USB-C** : For permanent power, connect an USB-C cable (**5V** / **0.5A**).

{% hint style="warning" %}
In mode **USB-C**, the **battery** must absolutely be **removed**. This mode completely eliminates maintenance operations related to battery replacement.
{% endhint %}

## Initial start-up

#### Battery

Powering the TX T\&H AMB is done by removing the protective tab from the built-in battery.

{% endcolumn %}

{% column %}

#### USB-C

Connect an USB-C cable. You can route the cable by breaking off the end of the tab on the rear tray.

{% column %}
To replace the TX T\&H AMB battery, you must first remove the sensor from its mount and clear access to the battery.

The TX T\&H AMB uses a 3.6 V lithium C battery.
{% endcolumn %}
{% endcolumns %}

If your sensor was still operating when you removed the battery, it may continue to operate thanks to the energy reserve stored in its supercap. You can force the supercap to discharge by [consulting this tutorial](https://www.youtube.com/watch?v=gRLy9dJJaSQ).

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://enless.gitbook.io/centre-aide/guides-installation/documentation-en/products/editor-1/use/power-supply-and-battery.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
