# Elios 3 Battery Best Practices
This article highlights essential practices to ensure good performance, reduce risk, and maintain warranty validity of the Elios 3 batteries.
Should you experience any battery-related issues, please consult the [**Elios 3 Battery Troubleshooting**](/aircraft/elios-3/elios-3-troubleshooting/elios-3-battery-troubleshooting.md) article for structured guidance on identifying and resolving common battery concerns.
### Remove batteries from the drone after use
* A battery will continue to discharge slowly and can reach a deep-discharge state, resulting in irreversible damage, when left connected for extended periods.
### Store Batteries at a low State of Charge
* Batteries stored empty or near empty can degrade quickly, resulting in irreversible damage,
* After a mission:
* When a battery is fully charged, manually set to Storage Mode in the battery menu, or allow the battery to set automatically (after 24hrs it will drop to 85%, then after 5 days it will start to discharge to 60%).
* When a battery is used. Recharge it fully before storing setting storage mode manually, or allow the battery to set automatically (after 24hrs).
### Cycle Batteries During Long Periods Without Use
* If batteries stay unused for months their stability drops, causing swelling or voltage issues, requiring a maintenance cycle every 3 months.
* Charge the battery fully, then activate Storage Mode, or allow the battery to set automatically(after 24hrs) to discharge it to 60%.
### Extreme Temperatures Can Affect Performance
* Cold environments increase internal resistance and hot environments accelerate chemical aging.
* Before flying, bring the battery back to a moderate temperature (around 20–25°C).
* Avoid long delays between conditioning and flight so the battery stays within a safe temperature range.
### Charging Considerations
* Always allow batteries to cool after flight before charging.
* Avoid charging batteries below 12°C or above 45°C.
* Charging should always be supervised in a safe area.

# 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://knowledge.flyability.com/aircraft/elios-3/elios-3-documentation/elios-3-battery-best-practices.md?ask=&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.
