Everyone who values the health of their car strives to buy the best jump starter. However, even high-quality models are sometimes used improperly, which erases all their advantages. You should conduct profound research before starting a vehicle since your wrong actions may result in battery death. After bringing it into an unrecoverable stage, you will have nothing to do but spend money on new equipment.

Read this article attentively. You will find out what voltage is enough to safely jump-start your vehicle.

Test battery’s voltage

The parameters of a jump starter depend on the battery type. Since it is challenging to provide some unified recommendations, experts advise car owners to discard guesswork and opt for individual testing. It is best to conduct this procedure once in two months.

The voltage turning a crankshaft in one cycle is exactly the minimum level needed to start a car. Keep in mind that modern vehicles do not have their own voltage measurement systems. Therefore, you have to find a device able to cope with this task, for example, a multimeter.

How many volts are needed for jump-starting a car

Even though most cars have 12-volt batteries, 12 V is not enough to jump-start a vehicle. If your measurement device shows this value, the battery is discharged. This may cause sulfation and shorten its lifespan. Therefore, you should always keep your batteries properly charged.
With a working generator and engine, they should normally operate at 13,7-14,2 volts. The higher level can overload the equipment, while significantly lower voltage is not enough for a full charge.

But what is the minimum voltage needed to start an auto? The answer would vary for different battery models and conditions, so you should not get surprised if you get a slight deviation from the average figures.

In a calm state, most batteries have 12,6-12,7 volts. At the same time, some brands provide models requiring 13-13,2 volts. In addition, the voltage increase may be conditioned by untimely testing. It is worth analyzing battery’s operation one hour after charging. Voltage should drop from 13 to 12,7 volts.

Environmental factors play a rather important role too. A decrease in the atmospheric temperature results in a decrease in the battery current. However, the difference from a standard state should not be way too notable. If you have less than 11,5 volts, your battery is likely to be half discharged. In order to avoid sulfation and preserve normal working capacity, you should conduct urgent charging.

It is quite possible to start an auto with a low voltage provided that equipment is new and does not require repair and the battery is charged from a generator while an engine is operating. The main thing is not to turn such jump-starting into a regular practice. Refer to this approach only in extreme situations. In all other cases, you should make sure voltage is 11,6 volts or above. It is best to have 12,2-12,4 volts.
