When you have a weak battery, the charging system (that is the alternator) and the starter motor will draw excessive voltage to compensate for the lack of battery power, thus they will be overworked and over time can malfunction.
If your battery voltage is too low, you might just need to recharge it. You can use a car battery charger for this purpose. Remember, though, recharging isn’t a magic cure-all. If the battery is old or damaged, it might be time for a replacement. The average car battery life is about 3-5 years.
If the voltage drops to between 12.0 to 12.4 volts, the battery is considered weak, suggesting it may struggle to start the vehicle. A reading below 12.0 volts indicates a bad battery. At this level, the battery is unable to hold a charge effectively and may need replacement.
Several factors can contribute to low battery voltage. These include: Aging Battery: Car batteries have a lifespan of 3-5 years, depending on usage, climate, and maintenance. As the battery ages, its ability to hold a charge diminishes, which can result in low voltage.
Reduced Lifespan of the Battery: Reduced lifespan of the battery occurs as prolonged low voltage conditions can lead to sulfation. Sulfation is a process where lead sulfate crystals form on the battery plates, decreasing the battery’s ability to hold a charge. This reduces battery life significantly.
If your battery voltage is less than 12.66 volts, it is not fully charged or will not retain a charge (or it can mean that the weather is impacting the voltage the battery has). When the temperature is 80 degrees Fahrenheit, a result of 11.89 volts indicates that your battery is completely dead or 0%.
