The car engine usually charges the car battery. In this manner, the battery always remains close to its full charge level for so long without needing a recharge or replacement. As long as the car is running, the battery will always have sufficient charge to sustain the electric demands of the car. However, the battery can accidentally run out of charge when the lights are left on while the engine is off. A dead battery can lead to a serious inconvenience especially when someone wants to use the car to rush for work. Nevertheless, recharging a car battery that is out of charge is not a daunting task. Understanding how to recharge batteries is a simple task that is straightforward and easy to follow as explained below.
1. Preparing for the Exercise
The first step is to get a trickle charger. The charger delivers electric power to the battery slowly and steadily. The steady rate ensures that the battery retains the charge for long. The trickle charger has clips for hooking at the battery terminals during the charging process.
2. Removing Dirt From Battery Terminals
The second step is to clean the battery terminals. Cleaning these terminals ensures that there is a perfect contact between the alligator clips of the trickle charger and the battery terminals. The battery terminals are usually covered with dried sulphuric acid which can be very dangerous when it comes into contact with the skin. Therefore, the terminals should be cleaned with sandpaper and a base compound such as sodium bicarbonate which neutralizes the acid making it harmless.
3. Opening the Cell Caps
Cell caps are small caps that are usually removed from the battery during charging. Removing these caps is very important because it ensures that the gasses produces by the battery during the charging process are safely released from the cells. Failing to open the cell caps can lead to an explosion because of the accumulation of the excess pressure in the battery cell compartments.
4. Connecting the Charger to the Battery
At this point, the car should be turned off, and the alligator clips of the charger should be connected to the battery terminals. The positive terminal and negative terminals of the charger should be attached to the positive and negative terminals of the battery respectively. At this point, a lot of care should be taken to prevent the charger terminals from coming into contact with each other as this would lead to a dangerous short circuit. Additionally, the short circuit could result in sparking at the terminals, and this can cause an explosion of the hydrogen gas coming from the battery cells.
5. Switching the Charger On
Once the charger terminals are connected to the battery terminals, the charger should be turned on after being connected to the socket outlet. The charger should then be left to charge the battery overnight. In the morning, the charger should be turned off, and the reading on its display should be checked. If the reading is less that one Ampere, the charger should be unplugged from the socket outlet. At this point, a hydrometer should be used to check the amount of electrical energy in the battery. If the battery is in excellent condition, the engine should turn on and start.
In a nutshell, understanding how to recharge batteries is very important in this era of technological advancements because it can save someone hours of taking the battery to a battery charging shop.
