A car battery should be replaced when its charge drops below 25%. A voltage reading of 12.6 volts means a full charge (100%). At 12.3 volts, the charge is about 75%. If the voltage falls to 11.8 volts or less, the battery is at 25% or lower. Schedule a replacement service if the voltage falls below 12.0 volts.
Cold Cranking Amps (CCA) is another critical measurement. CCA indicates the battery’s ability to start an engine in cold temperatures. A battery with low CCA may struggle to start your vehicle, especially in winter. Regularly checking the CCA can help gauge the battery’s overall health.
Expert advice suggests monitoring your battery’s voltage using a multimeter. A reading below 12.4 volts indicates a potential issue. Additionally, be aware of any signs of corrosion or leaks, which can compromise battery efficiency.
As you assess your car battery’s condition, consider weighty factors like driving habits and climate. The next section will delve into the signs that indicate it’s time to replace your car battery, helping you make informed decisions for your vehicle’s health and performance.
