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…
