# Elios 3 Battery Best Practices

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 href="#docs-internal-guid-857b4dca-7fff-9b4c-3b25-a1c3f9aaf367" id="docs-internal-guid-857b4dca-7fff-9b4c-3b25-a1c3f9aaf367"></a>

* 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 <a href="#docs-internal-guid-5b91046d-7fff-f396-7335-6061160cc5e3" id="docs-internal-guid-5b91046d-7fff-f396-7335-6061160cc5e3"></a>

* 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%).&#x20;
  * 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 <a href="#docs-internal-guid-131c9a98-7fff-3230-e110-410f57914f18" id="docs-internal-guid-131c9a98-7fff-3230-e110-410f57914f18"></a>

* 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 <a href="#docs-internal-guid-c70ecb1b-7fff-2293-dba6-e318278b385c" id="docs-internal-guid-c70ecb1b-7fff-2293-dba6-e318278b385c"></a>

* 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.
