The world of automotive technology is constantly evolving, and one of the most critical aspects of car maintenance is battery care. A dead battery can leave you stranded on the side of the road, and it’s essential to know how to revive it. One of the most common methods of reviving a dead battery is by jump-starting it from another car. But how long does it take to charge a dead battery from another car? In this article, we’ll delve into the world of battery charging and explore the factors that affect the time it takes to revive a dead battery.

Understanding Battery Charging
Battery charging is a complex process that involves the flow of electrical current from one source to another. When you jump-start a dead battery, the goal is to provide enough electrical current to recharge the battery and get the car started. The amount of time it takes to charge a dead battery depends on several factors, including the type of battery, the age of the battery, and the condition of the charging system.
Battery Type
There are two main types of batteries used in modern vehicles: lead-acid and lithium-ion. Lead-acid batteries are the most common type and are used in most cars. Lithium-ion batteries, on the other hand, are used in hybrid and electric vehicles. The type of battery you have will affect the time it takes to charge it. Lead-acid batteries typically take longer to charge than lithium-ion batteries.
| Battery Type | Charging Time |
|---|---|
| Lead-Acid | 30-60 minutes |
| Lithium-Ion | 15-30 minutes |
Battery Age
The age of the battery also plays a significant role in the charging time. Newer batteries tend to charge faster than older batteries. This is because older batteries have a lower capacity and may not be able to hold a charge as well as newer batteries.
Factors Affecting Charging Time
There are several factors that can affect the time it takes to charge a dead battery. These include:
- Age of the battery
- Type of battery
- Condition of the charging system
- Capacity of the battery
- State of charge of the battery

Step 1: Prepare the Vehicles
Before you start charging the dead battery, make sure both vehicles are parked in a safe location and the parking brake is engaged. Turn off the engine and all accessories in both cars.
Step 2: Connect the Cables
Connect the positive (red) cable to the positive terminal of the dead battery and the positive terminal of the good battery. Connect the negative (black) cable to the negative terminal of the dead battery and a metal surface on the good car, such as the frame or a bolt.
Step 3: Start the Good Car
Start the engine of the good car and let it run for a few minutes to charge the dead battery. You can check the voltage of the dead battery using a multimeter to ensure it’s increasing.
Step 4: Disconnect the Cables
Once the dead battery is fully charged, disconnect the cables in the reverse order that they were connected. Start with the negative cable and then the positive cable.
Conclusion
