Hundreds of 10C PRO and 10C CREW Battery Chargers are currently at work in a number of U.S. government settings. For example, at U.S. Postal Service mail distribution centers across the nation, 10C charging systems are now at work supporting standard maintenance and repair needs of mail sorting equipment and delivery vehicles. A proprietary USPS study estimates significant ROI due to implementation of the 10C approach as influenced by reduced recycling charges, extended battery life, increased equipment uptime and improved inventory controls.
