You can either use a battery charger, drive or idle for at least 20 minutes to charge the battery, or receive a jump start from another vehicle.
- You will need jumper cables and a car whose battery is not dead in order to jump-start your vehicle.
- Find a driver whose car’s battery is still good. Check to see if they have jumper cables. Find someone with jumper cables if they don’t.
- Place a working vehicle with a booster battery next to the vehicle with a dead battery, being careful to keep the two vehicles apart.
- Make that the booster battery is 12-volts and has the grounding wire attached to the negative terminal.
- Unnecessary electrical loads should be turned off.
- Remove the service cover from the engine compartment’s front passenger seat side by opening the engine hood.
- The make and model of your car determines how easily you can access your battery. Some might even be hidden behind the seats or in the boot.
- Take off the fuse box lid. Open the negative terminal cap near the car body and the positive terminal cap within the engine room fuse box.
- Connect the positive end of the discharged battery to the red, positive clamped end of a jumper cable.
- Connect the other end (red positive clamp) to the booster battery’s positive terminal.
- The other jumper cable’s (black, negative clamp) other end should be connected to the negative terminal of the booster battery, and the other end should be connected to a stationary, solid metallic object far from the battery.
- Start the engine of the working vehicle and let it run for a few seconds to start charging the dead vehicle’s battery with the jumper cables.
- When the dead car starts, unplug the jumper wires in the opposite order (first the black, negative clamps, then the red, positive clamps), being careful to avoid touching the clamps.
- To build up the charge, take a little drive or leave it idle for at least 20 minutes.
To charge your battery, adhere to the simple directions below:
- Make sure you turn off the battery charger.
- Connect the charger’s positive and negative cables to the appropriate ends of the battery.
- Turn on the charger when it is charging at its slowest rate, and then set the timer. It should take 6 to 12 hours to fully charge, depending on the battery voltage and cold cranking amps (CCA).
- After finishing, switch off the main battery charger.
- Negative and positive clamps should be disconnected from the corresponding battery terminals in that order.

How much time should a car be left running to fully charge the battery?
Keep in mind that after performing a jump start, you must keep the engine running for around 30 minutes to give the alternator enough time to fully recharge the battery.
Without a charger at home, how can I charge my auto battery?
You should be aware that using a charger alone is the best technique to charge a car battery. This is so because a charge is created to efficiently and correctly charge an automobile battery. Therefore, you should never use any other approach when a charger is available. You need to have the following things before attempting any of the following techniques for charging a battery without a charger.
- sturdy gloves that offer protection.
- shielding eyewear.
- cleaning brush made of wire.
- clip-equipped wire probes.
They should be kept in your car just in case you need them for anything, including securely charging your battery.
Method 1Use Jump Leads
You must jump-start your automobile when the battery is dead in order to at least get the engine to start. Once the engine is running, you can travel to your destination and charge your car there using a suitable charger. You must attach the jump leads from another vehicle to your car’s battery in order to jump start it.
You can use the jump leads to give your car battery exactly the right amount of power to start the engine. Jump leads won’t be of any assistance if your automobile battery is having problems, though. For guidance on how to connect the jump leads correctly, it is crucial to read the instructions that came with your car battery. If not, the battery in your automobile could be harmed. Here are some crucial actions to do.
- Clean the battery terminals using a wire brush to ensure that there is no corrosion, rust, or dirt present. Before connecting the jump leads, do this to ensure appropriate charging.
- To ensure that the current flows steadily and safely, the jump leads shouldn’t be larger than 6 gauge.
- To ensure that your battery has enough charge to start your automobile engine, the donor car’s engine must be running for at least 10 minutes while the jump leads are attached to your vehicle.
Method 2Use Solar Panel and Solar Charger
You can quickly charge your automobile battery if your home is equipped with solar panels. When your battery is dead, though, it is not very useful because it will take hours for the battery to charge before you can even start using it. Before connecting your solar panel to your automobile battery, you need be aware of compatibility. The ideal approach to attach a solar panel to a car battery for charging is using a solar charge controller.
Your automobile battery won’t overcharge thanks to a solar charge controller. A car battery’s lifespan can be shortened and damaged by overcharging. A controller actually has the ability to stop reverse current flow. When using a solar power source, the safest approach to charge your automobile battery is with a solar battery charger. Naturally, it will guard against reverse current and overcharging. In order to get the best charging time from a solar charger, be careful to consider the size of the automobile battery. A automobile battery may be fully charged by a 100W solar charger in around 8 hours.
Method 3Use UPS Inverter
Every home in the modern world has a home UPS inverter to draw power from the home inverter batteries in the event of a power outage. Typically, an inverter transforms the battery’s DC power into AC electricity. A typical home inverter battery is a 12V battery, which is the same voltage as a car battery.
As a result, you can use it to charge your car’s battery, but you should first check the handbook to make sure the inverter and its battery are compatible with charging a battery of comparable capacity. In fact, the majority of inverters incorporate displays to show the status of the charging process and guard against overcharging and reverse current.
Method 4Charge Battery By Putting It Into Another Vehicle
Placing your battery in another vehicle’s battery space is the simplest alternative if you lack confidence using jump leads, solar power, or a UPS inverter to charge it. This is only valid if the battery in your other car is comparable to the battery you want to charge. Avoid connecting the batteries to another vehicle if you are unsure that they are identical in terms of size, shape, and even specifications.
Otherwise, it can harm the other car’s internal components and batteries. You need specifically match the battery’s mAh. If the second vehicle’s engine won’t start after being connected to the battery or started, don’t push it or be intransigent about it.
Method 5Use A Car Jump Starter
In order to protect themselves in the event that their car battery fully dies, every car owner should have a jump starter in their vehicle. Just enough battery charge will be provided to start the engine. An alternator can be used to charge the battery after the engine has started.
Your automobile battery is definitely defective if you are unable to jump start it using a starter. Before jump-starting, you should unplug all additional connections to the air conditioner, multimedia system, and lighting. Additionally, use a wire brush to clean the terminals before joining.
Method 6Use A Battery Isolator
Last but not least, a battery isolator can be used to drive charge from the primary battery’s alternator to charge a secondary battery. Although it is not the most efficient method, it works. It could be difficult if the battery is completely dead, but it is still worth trying. Prior to supplying power to the battery isolator to charge the secondary battery, the alternator first charges the primary battery. For RVs and camping locations, a battery isolator is relatively typical.
