The short answer is no most car batteries do not come charged. The long answer is a bit more complicated.
The level of charge in a new battery is typically only around 40-50%. The reason for this is that batteries are shipped by rail or truck and the jostling they receive during transport can damage the delicate internal structure of the battery. It’s not uncommon for batteries to be damaged in transit and shipped with only a partial charge.
Additionally batteries discharge very slowly on their own. A car battery that sits on a dealer’s lot for a month or two will likely be completely discharged by the time it’s sold.
So if you’re buying a new or used car it’s a good idea to have the battery tested and if necessary replaced before you drive the car off the lot.
