The DEWALT DCB18 XR Bluetooth Slide Li-Ion Batteries pair with Apple and Android smart devices via the free Tool Connect™ App. This innovation gives DEWALT users the ability to control their compatible DEWALT batteries remotely via a Bluetooth device. From the Tool Connect™ App home screen, users can select an individual battery to view its diagnostics and change settings by tabbing through the pages: Diagnostics, Actions and Alerts. Diagnostics Screen: indicates an individual battery’s state of charge, temperature, and connection to Bluetooth®. It also allows users to enable and disable a particular battery. By disabling a battery, the user prevents it from being used until re-enabled. Making it easy to shut down equipment at the end of the day to conserve battery life and deter theft. Actions Screen: allows the user to customise their alert preferences depending on what information they need and when they need it. These options include Alert if Out of Range, Disable if Out of Range, Alert at Low Battery Charge, Alert at High Temperature, and Alert at Charge Completion. In addition, this screen offers a Lending Button, which allows for sharing of batteries. The user can select an amount of time for the tool (with battery) to be lent and when the time is exceeded, the battery shuts down and the owner receives an alert. Alerts Screen: provides a comprehensive list of all of the alerts that have been generated by the Tool Connect™ App and the compatible DEWALT Bluetooth® batteries. From here, users can select an alert to view more details or clear some or all alerts in the log. Compatible with all slide on DEWALT Li-Ion 18 Volt Tools. Specification: Battery Capacity: 5.0Ah.
