All of our Door Openers run on 4x AA batteries, and the type of battery used should be alkaline. This is due to lithium batteries having a higher risk of overheating in outdoor electronics and causing damage to the internals. Always ensure that you do not mix alkaline and lithium batteries as this could lead to performance issues.
During cold months, however, alkaline batteries are negatively affected by the low temperatures, and can run low very quickly.
To combat this, we suggest switching to non-rechargeable AA lithium batteries during the cold months, when the weather is consistently below 5°c / 41°f.
This is advised because there is no risk of the batteries overheating and damaging the electronics when temperatures are so low.
You MUST remove the lithium batteries when temperatures begin to rise again in the late Winter or early Spring.
Lithium batteries must be replaced with alkaline when the weather begins to warm again. If lithium batteries are used in the product during warm weather, this can cause fires which are not covered by your door opener's warranty.
Best Practices for Battery Usage
Always use the same type and brand of batteries in the device to ensure consistent performance.
Replace all batteries simultaneously to avoid uneven discharge rates.
Periodically inspect the battery compartment for signs of corrosion or damage.
Failure to maintain and check the unit will void the warranty if there are signs of battery damage
We recommend Energizer or Varta alkaline batteries in our unit rather than Duracell
Alternatively, your Door Opener can be powered using an external power source. Please see our "External Power Options" article. Our more recent style ChickenGuard devices, Pro and all in one can also be powered by mains electricity with a rechargeable battery backup. This setup provides uninterrupted operation during power outages by automatically switching to the rechargeable batteries.
