You copied and pasted last week’s question. 
But in regards to cold weather, Aosu provides some symptoms of a battery struggling due to low temps:
Lithium batteries naturally experience reduced performance in low temperatures due to slower chemical reactions. You may notice:
- The battery may not charge or drains quickly (e.g., 100% to 80% rapidly).
- Battery levels may drop temporarily but recover as temperatures rise.
- Charging may seem ineffective even in bright sunlight.
Here are some recommendations:
Tips for Winter Usage
- Indoor Charging: Install the camera in an accessible spot for easy removal and wired charging indoors.
- Lower Sensitivity: Adjust detection settings to reduce unnecessary recordings and save power.
- Solar Panel Check: Ensure the solar panel is connected and unobstructed for better charging.
- Battery Check: Test battery health by placing the device indoors at room temperature for two hours, then charge. If it reaches 100%, the battery is fine.
I’ve had to take down one of my cameras to charge in-doors twice this season. Fingers crossed it’s the last time.
