When a car battery is overcharged, the most common effect is the battery rapidly dying, however, a battery that swells and becomes hot to the touch is also a direct result of overcharging. When the battery swells, sulfuric acid can leak from the battery. This is potentially harmful when it comes in contact with the skin and should be avoided if at all possible and if not, needs to be washed off the skin immediately.Continue Reading
An overcharged battery will get hot and could even explode. The explosion will throw battery acid everywhere, endangering those within the vicinity of the explosion. If the voltage of the battery is overcharged, the battery will be severely damaged and have to be replaced.
As car batteries are used, the chemical properties begin to degrade. Over time, they will hold less and less energy, meaning their capacity decreases. This causes the battery to wear out faster each time the battery is charged. Connecting high-voltage chargers will then exhaust the worn out battery, potentially resulting in overcharge scenario.
Always use the correct charger when charging a car battery, and have it checked periodically by a specialist if charging must be done frequently. Pay attention to labels that indicate exactly how the battery should be charged; this helps eliminate overcharging and possible harm and injury.Learn more about Car Parts & Maintenance
If a car is hard to start, the issue is often the battery. While a dead battery does not turn the starter at all, a weak one turns it very slowly. This slow turn does not create enough compression to cause the fuel to ignite in the cylinders, making it difficult to start the vehicle.Full Answer >
To jump-start a car, apply jumper cables to the car's dead battery and the live battery of another car. Run the engine of the car with the live battery for a few minutes, then turn the key in the ignition of the car with the dead battery.Full Answer >
If a car makes a clicking sound but won't turn over when the key is turned, it indicates a problem with the battery or battery cables, the starter solenoid or the starter motor. The problem is almost always a dead battery.Full Answer >
Engine hesitation can be a result of low fuel pressure, vacuum leaks, worn or dirty spark plugs or bad spark plug wires. A weak ignition system can lead to misfiring, which can also cause hesitation.Full Answer >
