Two interchangeable power options are available to power your device: a PowerPrecision+ battery or a PowerCap™ capacitor. You can swap power options anytime on all DS8100 models, right in your facility, providing the flexibility to meet changing business needs while protecting your original investment. A PowerPrecision+ smart battery powers the DS8178 for over three around-the-clock days of continuous scanning on a single charge. And managing your power sources is easy. Since the PowerPrecision+ battery and PowerCap capacitor can report their model and serial numbers, you’ll always know which power source is in each scanner.
