Only with some help. A jump start will be necessary most of the time. Cars with manual transmissions can be push-started, but this is tricky and can be dangerous, so battery problems should be addressed right away.

There's no specific mileage interval or age when batteries fail. But the older a battery is, the more likely it is to die. Other factors that can affect battery life include the climate you drive in, how often you start the car (or let it sit idle), and proper maintenance of the starting and charging system.

If the battery dies, there may be other factors in its demise. Cars that have the symptoms of a dead battery should be properly tested using a machine. This device will test every part of the starting and charging system. If the battery's charge is too low, it will be recharged, retested and possibly replaced. Other parts, including the alternator, battery cables and wiring, may need repair or replacement, as well.

For most vehicles, battery replacement is typically fast and easy. First, apply the emergency brake, remove the keys from the ignition and turn off all electrical components.  Remove the negative battery cable first, followed by the positive cable. After removing both cables, loosen and remove the holding brackets. The battery will then be free for removal. When installing the new battery, always connect the positive cable first, followed by the negative cable. This order is important to avoid damaging the computers or software in the vehicle. Note that some vehicles place the battery in the trunk, the front or rear wheel well, or under the seats. In these instances, you may need to dismantle other components first.

The average useful life of a vehicle battery is around four years. This time will increase/decrease depending on the integrity and performance of the charging system.

High-quality replacement batteries are recommended due to the extensive electrical systems used in modern vehicles. The new battery must meet or exceed the specifications of the original battery.

It is important that the charging system is thoroughly checked after the new battery is installed otherwise you may have recurring issues.
