How to Tell if Your Car Battery Needs Replacing?

Model: (Various brands) Various
Part: Battery

Video tutorial

One of the main causes of vehicle failure to start is battery malfunction. However, it is important to distinguish between a non-functioning battery and a flat battery.

A flat battery does not alert the driver as it nears the end of its life cycle, usually occurring when the vehicle has not been used for months or when an electronic component, such as lights or the radio, has been left on. If the battery is flat, simply recharge it using jumper cables and another vehicle or battery.

A non-functioning battery, on the other hand, starts to give the driver warning signs before it fails completely, such as loss of power during acceleration, dimming lights despite new bulbs and functioning fuses, and some electronic components not turning on or working as they should.

If the battery is over four years old and shows these malfunctions, it is important to replace it as soon as possible.
