Sooner or later, most drivers encounter the inevitable inconvenience of a dead car battery. You don’t need to be an expert auto mechanic to know that without a running battery, your car won’t start at all. You’ll have to call a roadside maintenance service or find a way to get your vehicle to a repair shop in this situation. Both of these options are less than ideal. Alternatively, you have the option of avoiding these choices and charging your car battery yourself. So long as you have the proper equipment, like a portable battery charger, you can perform this task anywhere you need to, even when you’re stranded on the side of the road. Let’s break down how to charge a car battery.

Your car won’t start. What now? It might seem like your battery is dead, but if the lights and electrical systems are still running, your battery might just need a jump start. Follow these steps to give your

Learn the simple steps to jump starting your vehicle battery. STEP 1: Find Jumper Cables (Jump Leads)Read and follow the Safety and Handling Information on this website and with the jumper cables. You'll need a set of jumper cables and another vehicle with a charged battery. You can find cables in auto parts stores, at gas stations or just about anywhere you buy car parts. STEP 2: Park the car that needs to be jump-started next to a car with a good battery.Park the car with the good battery next to the car with the dead battery. Pull the car close enough so that the cables will easily reach from the battery of one car to the battery of the other. Shut off both engines and prop open the hoods or trunks, depending on where the batteries are located within the vehicles. STEP 3: Find the Red (Positive) and Black (Negative) Battery TerminalsFind the batteries and their terminals. Each battery has two metal terminals. One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery. STEP 4: Dead Battery: Identify a metal groundIdentify a metal ground within the vehicle with the dead battery. You can use the metal frame of the vehicle. STEP 5: Dead Battery: Attach the Positive Jumper Cable Lead to a Positive TerminalConnect a positive cable clamp to the positive (+) terminal of the dead battery. STEP 6: Good Battery: Attach the other Positive Jumper Cable Lead to a Positive TerminalConnect the other positive cable clamp to the positive (+) terminal of the charged battery. STEP 7: Good Battery: Connect the Negative Jumper Cable Lead to a Negative TerminalConnect a negative cable clamp to the negative (-) terminal of the charged battery. STEP 8: Dead battery: Attach the other Negative Jumper Cable Lead to a Metal GroundConnect the other negative clamp to the metal ground of the vehicle with the dead battery. You can use the engine block or another metal surface of the vehicle away from the battery. This is the last connection you need to make. STEP 9: Dead Battery Vehicle: Start the CarStart the car with the charged battery. Wait one or two minutes and try to start the car with the dead battery. If the car starts: Remove the black negative clamp from the ground of the vehicle needing the jump. Remove the black negative clamp from the assisting vehicle. Remove the red positive clamp from the assisting car. Remove the red positive clamp from the formerly stalled vehicle. If the car doesn’t start: Wait a few moments and repeat Step 9. We recommend fully charging your battery at the first opportunity after its being jump-started. Can you use another car to charge a car battery?Jumper cables can supply power via a functional battery from another car. Keep a set in your vehicle. Connecting your car's battery to another car's battery with jumper cables is a common way to recharge a battery. Park the vehicles so their batteries are as close as possible.
Can you take a battery from one car to another?No. Car batteries differ in multiple ways to work with different vehicle's specifications, and they are generally year, make, model-specific. Many car batteries do have one important similarity in how they work.
How can I boost my car battery with another car?Steps to Jump a Car Battery. Step 1: Connect red to dead + (positive battery terminal). Step 2: Connect red to donor + (positive battery terminal). Step 3: Connect black to donor – (negative battery terminal). Step 4: Connect black to dead, bare metal.. Step 5: Start donor vehicle.. Step 6: Start dead vehicle.. How long does it take to charge a dead car battery with another car?Recharging a battery with a typical charge amp of around 4-8 amperes will take about 10-24 hours to charge fully. However, if you just want to boost your battery enough to start the engine, it would take about 2-4 hours—or, if possible, you can use another vehicle to jumpstart your battery.
