Your battery has any troubles or not when being used? We usually call the issue as “won’t hold a charge” any more or other worse conditions. However, it is not some good ideas for you to understand whether your battery can work properly or not. You can test your battery right at home and determine it is bad or good.
The first is Inspect the battery.
For a battery, there are several things to inspect such as a broken terminal, bulge or bump in the case, rupture or crack of the plastic, excessive leaking and more things discoloration. Broken or loose terminals can cause a short circuit so they are very dangerous. Once a short circuit occurs, there would be indication of melting or burning. All of the power is unloaded in an instant if they have a short. That produces heat and even results in the battery to explode. The battery will be overcharged if it is still intact but there is a bulge in the case. Also, different signs like physical openings in the case can be caused by mishandling. If you let cracks, splits and holes damaged, a battery will not stop working but damage of unsafe issue must appear.
The second is Load test the battery.
To achieve this task you need to have a digital voltmeter. When the load test is accurate, the battery must be fully charged. For example, we test a motorcycle batter. Remove the seat and expose the battery in your motor to access to the terminals easily. During the process, do not disconnect the battery because you can make an attempt to start the bike if possible. Then, hold the prongs of your voltmeter to the correct terminals on the battery. You can push the start button and watch what the voltage drops to now. In case the bike does not start as common, you need to have a voltage reading to test more.
For each mean, the volt is different. With 12 volt motorcycle battery should remain from 9.5 to 10.5 volts with the load for a good 30 seconds straight. The problem appears when the battery begins starting to hold and then steadily drops in voltage. Or if the voltage instantly drops to 0 volts, it also means there has trouble. These issues are usually called as Open Cell issue. Open cells will read fully charged in idle but they fail under a load test each time. When a battery reaches this point, there is no going back thus the best thing you should do is recycle the thing.
The third is have Voltage reading.
As the second part claims, the voltage of the battery is an ideal way to confirm whether the state of charge is full or not. If your battery is reading 0 volts, the chances of a short circuit are very easy. If the battery cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell. When the battery is fully charged but the voltage is just 12 or less, the battery is sulfated. It can be said that the voltage shows the status of your battery exactly. Therefore, you are easy to understand when you should charge the battery and how to have right charging to keep its longevity.
The above 3 steps are not so difficult to process but being helpful for you to determine your battery is truly bad or getting there. More importantly, you can do them right at home and gradually every day. Also, different types of battery will give you different ways to access. The flooded batteries make it possible to simply look inside the cells and show if the battery has a physical defect. Meanwhile, AGM batteries and Gel ones require testing, certainly. And everything becomes easier if you have a battery charger and digital voltmeter. In case you understand that the battery is bad enough to be replaced, it is time for you to get a new one for your machine.
