# What is the MS-7K-U battery temperature derating behaviour?
## Understand how the MS-7K-U battery adjusts its performance at different operating temperatures.
The MS-7K-U battery automatically limits its charging and discharging power at high ambient temperatures:
- **Charging**: Power derating begins above 45°C.
- **Discharging**: Power derating begins above 35°C.
- **Above 55°C**: The curves show that charging and discharging power are reduced to zero. This does not necessarily mean the entire system is powered off.
Please refer to the below power derating curves for details. These temperatures refer to **ambient temperature**, rather than internal battery cell temperature.
