How charged must the battery be to start?

A car battery should be around 12.4-12.6V to start properly; low voltage can make starting difficult.

To start a vehicle, it is ideal that the battery has a certain minimum voltage level. It is generally accepted that a lead-acid battery, such as a standard car battery, should have a sufficient voltage of about 12.4 to 12.6 volts to start reliably. This is considered a “full” battery.

However, it is important to note that the voltage of a battery is not the only factor that affects starting a vehicle. In addition to voltage, the internal resistance of the battery also plays a role. A battery with a lower voltage but low internal resistance can still provide enough power to start the vehicle.

In practice, it may happen that a vehicle with a battery that is slightly below the ideal voltage can still start. But if the battery voltage is too low, the vehicle may have difficulty starting or may not start at all. It is also important to note that in cold temperatures, when the battery is less efficient, a higher voltage may be needed to start the vehicle.

If you notice that your vehicle is having trouble starting, it is advisable to check the battery using a voltmeter or a battery tester. This will allow you to measure the battery's voltage and determine if it is sufficiently charged. If the battery voltage is too low, it may be necessary to recharge or replace the battery.

It is always recommended to consult the specific recommendations of your vehicle's manufacturer regarding the ideal voltage and maintenance procedures for the battery.
