Winter Warning for aosu Users
As temperatures drop, your outdoor aosu solar camera might start acting a little… frosty. Here’s what to expect and how to keep your setup running strong.
Cold Weather Battery Behavior
Lithium batteries slow down in low temperatures due to reduced chemical activity. That means:
- The battery might not charge or could drain quickly (e.g., 100% to 80% in minutes).
- Battery levels may dip temporarily, then bounce back as it warms up.
- Charging might appear ineffective, even in full sunlight.
Below –20°C, the battery may stop accepting a charge altogether — even when plugged in.
These aren’t defects — just normal cold-weather quirks. Once things warm up, performance should return to normal.
Tips to Stay Powered in the Cold
- Charge Indoors: Mount your camera where it’s easy to remove and plug in inside.
- Adjust Sensitivity: Lower motion detection to conserve battery.
- Check the Solar Panel: Make sure it’s clean and getting full sun.
- Test the Battery: Bring the camera inside for a few hours, then charge. If it hits 100%, your battery’s healthy.
Stay warm, stay safe, and keep your aosu gear ready for action. For help, aosu’s online support is just a click away.

When temperatures fall below –20°C, the Aosu camera’s battery may stop accepting a charge altogether, even if it remains plugged in. This occurs because extremely low temperatures slow down the chemical reactions inside the battery, reducing its ability to store and transfer energy efficiently. Prolonged exposure to such cold conditions can also temporarily decrease battery capacity and performance until the temperature rises back to a safe operating range.

When temperatures drop below –20°C, the battery may no longer accept a charge, even if it’s connected to power.

Typical cold limits for lithium-ion batteries
Here’s the general rule, depending on the battery chemistry. Almost all modern including AOSU cameras use lithium-ion or lithium-polymer batteries):
1. The battery might not charge or could drain quickly (e.g., 100% to 80% in cameras minutes).
2. Battery levels may dip temporarily, then bounce back as it warms up.
3. Charging might appear ineffective, even in full sunlight.
4. Below –20°C, the battery may stop accepting a charge altogether — even when plugged in.
What to do
1. Charge Indoors: Mount your camera where it’s easy to remove and plug in inside.
2. Adjust Sensitivity: Lower motion detection to conserve battery.
3. Check the Solar Panel: Make sure it’s clean and getting full sun.
4. Test the Battery: Bring the camera inside for a few hours, then charge. If it hits 100%, your battery’s healthy.
5. If it still won’t charge after warming up, the cold exposure might have permanently reduced its capacity or damaged the cells. Please contact AOSU support

The charging efficiency of lithium ion batteries is impacted significantly at temperatures below 40°F / 4°C, with the potential for it to stop accepting a charge entirely below -4°F / -20°C.
Some of the symptoms might include the battery not charging or draining quickly (e.g., 100% to 80% rapidly) and not getting the same level of charge even on sunny days. This is situational and can improve as higher temperatures role in.
Aosu suggests these tips for using your cameras in the winter:
-
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.

Usually, the AOSU camera’s battery may stop accepting a charge altogether when temperatures fall below –20°C. If this happens,
· Charge Indoors: Mount your camera where it’s easy to remove and plug in inside.
· Adjust Sensitivity: Lower motion detection to conserve battery.
· Check the Solar Panel: Make sure it’s clean and getting full sun.
· Test the Battery: Bring the camera inside for a few hours, then charge. If it hits 100%, your battery is healthy.
· If it still won’t charge after warming up, the cold exposure might have permanently reduced its capacity or damaged the cells. Please contact AOSU support
Fortunately, in the UK the weather temperature rarely falls below -20 degrees Celsius. But if it does. security cameras including the AOSU cameras’ battery may stop accepting a charge altogether. There are a few ways to tackle this problem, such as: charging the batter indoors, adjusting Sensitivity, checking the Solar Panel and making sure it’s clean and getting full sun, testing the Battery (bringing the camera inside for a few hours, then charging it. If it hits 100%, your battery is healthy)
