Purkeys’ 6-Station Battery Charger

Fleets have trouble keeping batteries fully charged in cold weather. Batteries produce energy through a chemical reaction. As temperatures drop, so does the rate of reaction. This contributes to batteries producing less energy. If batteries don’t produce enough energy to meet the cranking requirements, fleets will have trouble starting their vehicles. This leaves fleets with…

CAPS in the Cold

It is well known that fleets perform more jumpstarts during the cold winter months. This happens because cold motors require more energy to start and the weather can cause batteries to produce less energy. To combat these cold weather conditions, fleets need a jumpstarter that is powerful, portable, quick, and safe. Purkeys’ Capacitor Actuated Portable…

Reduce No-Start Situations this Winter

It is harder to start vehicles in the cold, because the energy requirements to crank an engine increase, while the battery’s ability to produce energy decreases. As temperatures drop, vehicle energy requirements go up, mainly because of engine oil viscosity. Viscosity refers to the thickness or consistency of a fluid. Lower temperatures make the oil…

Testing Diodes with Multimeters

The multimeter combines multiple electrical diagnosis functions into one portable unit. Technicians can use this tool for a variety of applications, including measuring voltage drop, continuity checks, diode checks, capacity checks, and more. In the video above, Purkeys National Truck & Fleet Representative, Larry Rambeaux, demonstrates how to conduct a diode check using a multimeter.…
