Car batteries remain charged with harnessing the additional power of the car engine, and most can last for at least five years without having to be replaced or recharged, but even the best car batteries will eventually run out of energy, or they will lose prematurely when they leave your lights on for too long It may be a serious inconvenience to find yourself with a non-charged battery, but recharging may require very little in terms of tools or mechanical expertise.
Charge the car battery with an electric charger
1- Place the charger on a stable surface, and never put the battery charger directly on the battery because it may connect the negative and positive stations, causing damage to the battery and the charger and possibly even lighting a fire, instead place the charger on a stable surface away from the battery and away from the cables, Before connecting the charger to the wall, ensure that the area is well ventilated by opening the garage door or windows if you are inside.
2- Make sure that the surface that the charger places is strong and stable to prevent it from dropping or disconnecting the battery, and use the full length of the cables to separate the battery from the charger as much as you can.
3- Connect the charger to the battery, connect the black cable from the charger to the negative sign (-) on it on the negative terminal on the battery that has the same symbol, then connect the red cable with a positive sign (+) to the positive terminal on the battery with the corresponding code, Be sure to check the connections before plugging in or turning on the charger, because mixing the positive and negative sides may damage the battery or even fire.
4- Some cars may designate the positive terminal with the letter POS instead of the positive symbol (+) and NEG instead of the negative symbol (-), and ensure that the cables are securely connected to allow electricity to flow from the charger to the battery.
5- Adjust the charger, digital chargers may refer to the voltage in the battery and allow you to set the final voltage level, while older models may simply allow the shutdown and shutdown, and speed chargers will also allow you to choose the speed at which you want to charge the battery (often done Photographed by a photo of a turtle versus slow charges and a rabbit for fast devices), and fast charging is useful for the car battery as a result of leaving your lights or anything in this sense.
6- If you can control the voltage that the charger will stop on, set it to the specified voltage on the battery or that you found in the car owner’s manual, and never set the charger to fast charging if you will leave the car unattended, and you may want to leave the battery slow charging overnight Overnight for a full charge if he has died for some time.
7- Check the battery, after allowing the battery to charge, check this to make sure that it is working, and some digital chargers will provide you with a reading that tells you whether the battery holds the charge correctly or will need to replace the battery, and this is often indicated by a percentage such as "100%" As in the case of the battery 100% charged, you may also want to use a voltmeter to measure the battery voltage once it is disconnected from the charger by touching the positive and negative cables from the voltmeter to the ends of the battery, and if the battery is still in the car then it may be the easiest way to check So it is connecting it again and trying to start the car.
8- If the voltmeter reads a suitable number of volts for the battery, then the charger indicates that it is good, or that the car starts operating the battery sufficiently charged, and if the voltmeter or charger indicates that the battery is bad or that the car will not start, there may be other problems that need to be resolved Or, you may need to replace the battery.
Safety steps when charging the car battery
1- Using appropriate safety equipment, safety is of the utmost importance at any time you work on your car, so start wearing protective goggles to protect you from any material that falls under the car hood, sparks or battery fluid if the battery is exposed to danger, and you may also want to wear gloves, and make sure Ensure that the area you work in is well-ventilated and illuminated enough to allow you to see where you are going and what you are working on, and gloves are not necessary but may protect your hands from discs and small cuts while working on your vehicle.
2- Make sure that there are no children in the area while working on the car battery, as sparks can fly if the positive and negative cables come into contact with each other.
3- Determine the type of battery To charge the battery properly, you must first determine the type of battery that you have, and you can usually find this written somewhere on the battery, but you may need to check the manufacturer's website if the poster is in the reading or Missing, and you should also find out the battery voltage by looking at the battery sticker or checking your car owner's manual.
4- Read the charger's instruction manual to ensure that you are using your own unit correctly, and the new digital chargers must be closely monitored during charging to ensure that they are working properly and stopping before overcharging the battery.
Types of car batteries
1- Wet cell batteries may be serviceable, which means there are things you can do to help improve battery life and battery life.
2- VRLA batteries, which are a regulated lead acid battery, are completely sealed and do not require maintenance, and are less common in cars.
