One intuitive feature of this battery maintainer is the fact that it is temperature compensated. This means no matter the temperate, it will automatically adjust to ensure that the battery is charging to the correct voltage. Once the battery reaches its full charge, it will automatically switch to a float mode to keep the battery topped up.
