Compatible with all SCOTTS SYNC System tools, this accessory charger is in a class of its own. Its innovative wall mounting feature allows the tool to hang on the charger while the battery re-charges to keep your work space organized. Or if you have an extra battery and need to keep using the tool, you can charge the battery alone like a traditional charger. With a 45 minute re-charge, you're never far from getting back to work. All backed by a 3-year warranty.
