Have you ever had such an unpleasant surprise, for example on a winter morning when you were rushing to work?

If so, you probably know what to do in such a situation. If not, you should know how to charge a battery, and how to prevent it from discharging. Here is a short guide on how to win against cunning fate.

Reasons for battery discharge

Why does the battery actually discharge? Is there only one cause or may failures in its operation occur for several reasons? Most often, this is due to the operation of electrical devices after removing the key from the ignition. Drivers usually forget to turn off their lights, and in the morning it turns out that this will unfortunately prevent them from driving. It is also crucial to choose the right battery for your car.

Freezing temperatures cause the amount of available energy to decrease and create more resistance when starting the vehicle. Please ensure that the battery is charged at all times.

How to use the battery?

total battery discharge affects its service life. If this happens to you often, you may have to replace it much earlier than planned. To avoid this, you should take proper care of it and follow a few simple rules. Check the battery voltage regularly, which should be greater than 12V at rest but less than 13V, it should not exceed 14,5V after starting. You will also find information about the electrolyte level in the battery manual. If it is too low, raise it and top it up with distilled water. Battery discharge it also depends on his age, if he is over 6 years old, the risk of discharge is greater.

After a few minutes, the battery will start working.

Driving short distances

You already know that driving short distances does not have the best effect on the state of charge of your battery. Its charging time while driving is too short, which causes its power to systematically decrease. As a result, there comes a time when he is no longer able to start the vehicle. How to check the battery, Is it charged or does it need to be recharged?

Check its idle voltage, which is best when it is 12,4-12,6 V. If the value is lower than 12V, it means that it is partially discharged. Less than 10V is a signal that the battery in your car is not in the best condition or needs to be charged. Use a simple meter to check the battery. A very practical gadget for every driver.

Don't let yourself be surprised! Take care of your car's battery, monitor its charge level, and charge it regularly using a special charger. You'll also need jumper cables in case you forget that your battery needs your attention.
