How to start a car engine with a discharged battery?

Even with a discharged battery, there is always an opportunity to start the engine using alternative methods. There are two main schemes for this: using time-tested starter wires or innovative boosters. You can improve your car and make it more original with tuning accessories, a large assortment of which is available in our online store.

Jump wires: a simple and reliable solution

Jump leads are not a source of power, but can be an effective way to start an engine with a dead battery. However, this will require another vehicle with a working battery.

Advantages of starter wires:

• Budget in comparison with boosters.
• The possibility of using the battery of another car.

Disadvantages of starter wires:

• Poor quality of many commercially available wires.
• Thin and not always copper wires, which can lead to overheating and damage when transmitting high current.

Homemade starting wires

For more reliable cigarette lighter wires, you can create them yourself. For this, you will need alligator clips and thick wires of at least 16 mm².

Advantages of homemade wires:

• Great strength and efficiency compared to commercial counterparts.

Disadvantages of homemade wires:

• Unsightly appearance.
• More weight.

Boosters: a reliable and convenient solution

Boosters are a source of energy, making them a convenient option. It is important to consider that the type of booster can significantly affect its characteristics.

Advantages of the booster:

• Independence from the presence of another car.
• Lithium-ion boosters retain their charge for several weeks.

Disadvantages of boosters:

• Lithium-ion boosters can lose effectiveness at low temperatures.
• Capacitor boosters may not help if the battery is completely discharged.

Recommendations for using boosters

• Before long-term storage of lithium-ion boosters, it is recommended to charge them.
• Capacitor boosters can be charged from a half-discharged battery.
• When using the booster in the cold, it is recommended to warm it up.

It must be remembered that in the event of a complete discharge of the battery, the capacitor booster may be ineffective. In this case, it can be recharged from another car.

Conclusion

Regardless of the method chosen, car owners should have both jump wires and a booster on hand. This will ensure the ability to quickly and safely start the engine in the event of battery discharge.
