General Information
Under normal operating conditions, the batteries in the Automatic model typically last between 4 and 6 years.
However, extreme weather conditions; such as very high or very low temperatures, may reduce battery lifespan.
For Automatic models equipped with a winter mode switch (pre-2025 versions), it is important to turn the switch to “off” from September 1 through May 1. During this period, reduced sunlight may prevent proper charging, which could cause the batteries to fully discharge and require replacement.
