By testing battery voltage, amperage, recovery time and discharge rate, it will reveal the overall condition of the car battery. It will also give you an idea if it is overcharged.
Unfortunately, repairing an overcharged car battery is not possible but rebuilding it is. When I say rebuild the car battery, this means reconditioning it to allow it to regain its ability to store charge and convert it to energy. There are battery reconditioners available in the market that you can use to rebuild your overcharged car battery, or you can also take the battery to licensed mechanics and pay them for the service. To keep you from dealing with the hassle of handling an overcharged car battery, preventing it from happening is the best step that you can take.
To help you with this, here are some tips that you can keep in mind. One of the best ways to prevent overcharging your car battery is to learn the proper way of charging it. Different battery types and battery chemistry has different ways of charging them properly. So you have to make sure that you know what battery type and chemistry your battery has and learn the proper way of charging it.
Or you can also study the different types of batteries, and the different battery chemistries then determine the appropriate way of charging them. For car owners that are recharging their automotive batteries using a battery charger. You have to make sure that you are using a non-faulty battery charger since it can lead to overcharging.
You also have to make sure that you are using the right battery charger to recharge your car battery. By doing this, it will eliminate the risk of having an unlimited amount of electrical charge delivered to the battery. As mentioned earlier, one of the causes of an overcharged battery is a failing alternator. For modern vehicles, an alternator with a faulty voltage regulator can also cause overcharging.
So make sure that your alternator is in good condition and is working as it is expected. Most of the newer battery chargers today are equipped with microprocessors that make them smart devices that allow them to have an overcharging protection feature.
Using smart battery chargers like these will let you leave the charger unattended without worrying for your battery to be overcharged. An exploding battery is bad enough, but it will also spray around the immediate area.
Battery overcharging can be a problem for car batteries. There are some telltale signs to look out for whenever you open the hood or have the car serviced. If the sides are warm or even hot to the touch, it indicates overcharging.
You need to do this check after driving the vehicle for at least 30 minutes or more. When overcharging for a long time, the overproduction of gasses inside the battery causes this swelling and bulging.
The problem must be found and fixed, and the battery replaced ASAP. When the vehicle engine is off and all the accessories are turned off, the voltage across the terminals should be around Now start the vehicle and measure again.
You will need an assistant for this as the engine revs need to be increased a little as you measure. With the engine running, the alternator is supplying a charging current to the battery. Ask your assistant to increase the engine revs gradually.
The voltage should rise to a maximum of around If you have a higher voltage than this, then your regulator is most likely defective. Taking a battery apart to replace the lead plates is just not cost-effective. However, you can recondition your car battery by using Epsom salt and distilled water. It helps bring your dead car battery by cleaning it of sulfates and replenishing it with electrolytes. The answer, unfortunately, is yes, and if you are new to vehicle ownership and maintenance, it can be very easy to do.
You should look out for car battery overcharging when you are maintaining your car. It is not an easy issue to fix, but if you know what signs to look out for or how to prevent it from happening you can keep your car maintained. If you are not careful, car battery overcharging could lead to serious damage to your vehicle and to the battery itself, so below we look at what car battery overcharging is and how to check if this has happened. Modern cars have batteries that are charged by an internal voltage regulator known as an Alternator.
This provides the car battery with a steady and controlled electrical charge while the car is in use. When this regulator fails, however, unregulated electrical charges can continue to power the battery, which leads to car battery overcharging. You can also overcharge your battery with human error — that is, by not knowing how to use car battery chargers, using amp settings that are too high, or setting an incorrect voltage.
If you have left your car battery charger unattended overnight, you can also overcharge it, which can cause damage to your battery. Now you understand a little bit more about car battery overcharging , you are probably wondering how you can check this is happening. Below are some simple tips for how to check for car battery overcharging. Important: Regardless of this, protective glasses and gloves should be worn when servicing, removing or installing the battery.
To prevent short circuits, it is essential to avoid connection of the terminals by contact with metallic or conductive materials, as otherwise there is a danger of electric shock or physical injury. Charging of the battery in the vehicle is simpler and is preferable for safety reasons, although this is not always possible. If no garage or an electricity connection is available, there is often no alternative to charging the battery outside of the vehicle. Ensure good ventilation when charging in enclosed spaces.
If the battery is removed from the engine compartment for charging, a second person should help to lift large batteries due to the heavy weight. Important : With lead-acid batteries, the formation of explosive hydrogen and de-gassing must be expected during charging.
In extreme cases, a high concentration of hydrogen may result in an explosion with serious injuries and damage. Defects of the battery should also be noted.
Acid may leak from damaged batteries. Physical contact with battery acid can cause serious burns. The affected area must be thoroughly rinsed with clean water and a physician must be consulted immediately. Important : The cable which is connected to the negative terminal must be disconnected first. This prevents a short circuit between the positive terminal and ground. Then disconnect the red cable which is connected to the positive terminal.
For lead-acid batteries which are not maintenance-free, we recommend that you visit a workshop. Under no circumstances should you check the acid-water level yourself. With maintenance-free batteries, checking of the electrolyte is not necessary.
Here, only the dirt needs to be cleaned from the vent pipes. Regardless of the reason for charging for example in the case of a dead battery, long standstill times, short journeys , it is advisable to have a battery test carried out by a workshop from time to time.
