When your batteries get excessively drained, the soft lead sulfate crystallizes. On normal cycles, the build-up of crystals is temporary and reverses when you recharge the batteries. Sulfation is the formation of lead sulfate crystals on the battery’s lead plate surface. If the voltage of your battery gets too low, it will get damaged because of too much sulfation. What Happens When Your Battery’s Voltage Gets too Low?
The life of your battery will be greatly affected if it stays in this volt range for longer periods. If it goes below 12.0V, your battery is considered flat or fully discharged and needs to get recharged immediately. The lifespan of your battery will get slightly affected if it stays within this range for longer periods. However, it’s best to recheck its status within a few days to guarantee that its voltage hasn’t dropped further.ġ2.4V to 12.1V means your battery is slightly discharged and needs recharging as soon as possible. If the voltmeter gets 12.5V, your battery is still healthy. That means it’s all good, and no further action is necessary. When your battery is 12.6V or higher, it is healthy and fully charged. When you have one, check the battery voltage to determine what you must do next. To check its voltage, you need to use a voltmeter which you can purchase from most auto parts shops. If your battery is always fully charged, it will last longer than batteries that are undercharged or kept at lower voltages. Remember that the voltage in your battery is kept plays a huge role in determining its service and performance. Checking the Battery Voltage for Better Performance If it goes lower than 12V, your battery will get damaged because of too much sulfation. Anything under 12V means the battery is dead. So, any reading below that means that it needs to be charged. A standard 12V battery usually has around 12.6V when you fully charge it. Remember, the battery can only be deep-cycled a certain number of times before it’s considered dead. The battery is either useless or deep-cycled. If the battery’s resting voltage is only 12-12.1, it means only 20-25% of the useful energy is present. When your battery reads only 12V, it’s almost entirely depleted.
