Bruce Purkey knows where the electrons go. And, as president of Purkey’s Fleet Electric and his many activities in the Technology & Maintenance Council of the American Trucking Associations, he’s well aware that some of them flow to batteries that support the electric-over-hydraulic systems for liftgates on trucks and trailers. Usually there are two and as many as four Group 31 batteries, like the ones on a truck or tractor.
