  • uSTART® Lead-Free Replacement for Truck Batteries

    ONEONTA, N.Y.Jan. 9, 2019 /PRNewswire/ -- Ioxus uSTART® has received two fleet industry awards for sustainability by eliminating lead-acid batteries with its ultracapacitor-based, drop-in battery replacement.

    "With uSTART, fleets not only realize the benefits of improved starting reliability, there are equally important and real sustainability improvements from lead waste reduction," said Chad Hall, executive vice president and co-founder of Ioxus. "By replacing one of the batteries on a vehicle with a uSTART module, up to 15 fewer batteries are needed over the lifetime of the vehicle. This translates into 1,000 pounds of lead that will never need to be disposed of or allowed to affect groundwater."

    EU legislation on batteries is embodied in the European Battery Directive.  Its objective is to contribute to the preservation and improvement of environmental quality by minimizing the negative impact of batteries and battery waste.  As these preservation efforts expand, sustainable technologies develop to manage and mitigate these risks.

    Replacing a lead-acid battery with uSTART in a typical commercial vehicle creates measurable environmental benefits:
