Does a New Car Battery Need Charging?
1 Answers
Yes, a new car battery needs charging. New batteries come from the factory with some charge, but not fully charged. Some batteries develop high internal resistance after prolonged use, reaching full charge quickly but discharging rapidly as well. These batteries may show normal no-load voltage when tested with a multimeter, so it's important to not only measure the no-load voltage but also the discharge current, which can be tested using a discharge tester. Car batteries, also known as storage batteries, are a type of battery that works by converting chemical energy into electrical energy. They are categorized into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. Typically, when people refer to car batteries, they mean lead-acid batteries. The normal service life of a car battery ranges from 1 to 8 years, depending largely on the vehicle's condition.
