# Storing the Battery

This section describes how to properly store the DeltaQuad Evo Li-ion baterry.

{% hint style="warning" %}

* The battery should be stored in a safe, dark location at temperatures between **5 and 30 degrees Celsius**. 
* If the battery is fully discharged or fully charged, perform a storage charge (approximately 50% charge or 3.7V per cell) before long-term storage. Use the **Storage** mode on the charger for this purpose. Storing batteries at 50% charge helps reduce stress on the cells, which can significantly extend the battery’s overall lifespan.
* During long-term storage (3+ months), it is recommended to cycle charge the batteries at least once. Fully charge the battery to 100%, then discharge it to a storage charge level of 50%.
* Keep the battery out of reach of children and animals. Avoid placing it near heat sources, such as furnaces or heaters.
* Always keep the battery dry and do not expose it to water or any other fluids. 
* Remove the battery from the UAV when it is not in use.
  {% endhint %}

{% hint style="info" %}
The lifespan of Li-ion batteries is often measured by the number of **charge-discharge cycles** they can undergo before their capacity degrades to a certain point, usually around 80% of the original capacity. The DeltaQuad Evo Li-ion battery is rated for 600 or more cycles before noticeable degradation occurs.

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://docs.deltaquad.com/tac/setup/deltaquad-evo-battery/storing-the-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.
