How to connect the charger to the battery? Quick Guide to Battery Charging
Content
It's safe to say that one of the most difficult activities for car users is to connect the charger to charge the battery. When you turn on the ignition but can't start the engine and your car's headlights dim significantly, your car battery is probably too low. There can be many reasons for such situations. When you need to start a car with a weak battery as soon as possible, be sure to call for help and connect the charger clamps to the battery. In the following post you will find a quick guide on how to connect the charger to the battery.
How to connect the charger to the battery? Step by step
Have you noticed that your car's battery is draining and you're having trouble starting your car? Then you need to charge the battery with a professional charger. You can do this in two ways:
- Remove the battery from the car and take it, for example, to a garage for charging.
- Connect the charger directly to the vehicle with the dead battery.
Before you charge the battery with a charger, take care of your own safety, as well as the safety of the car. Make sure the charging and clamping area is dry and free of metal objects. After checking the level of security around the battery, you can proceed to connect it to the charger. You will do it in a few simple steps:
- Disconnect the battery from the car - simply remove the negative and positive clamps that are connected to the car's electrical system.
- Connect the charger clamps to the battery - remember the correct order. Be the first to connect the red clip to the red pole marked + and the black clip to the negative pole marked -.
- Connect the charger to a power source, such as in the garage or at home.
- Select the charging mode on the charger (if you have one) - on professional chargers, you can even set the operating temperature of the device while charging.
- Wait patiently for a fully charged car battery. In the case of highly discharged cells, this can take up to a day.
How long does the battery take to charge?
This is a simple guide that will allow you to correctly connect the rectifier, but not only. The professional charger also allows you to check the current flowing in the battery. You should also keep in mind that the download time depends a lot on several factors:
- battery level,
- battery capacity.
When connecting connecting cables or the charger, never reverse the battery poles. Otherwise, you will get a short circuit and eventually even damage the car's power supply.
Disconnecting the battery from the charger - how to do it right?
Charging a car battery takes several to several hours, depending on what effect you want to achieve. After the charging process is completed, disconnect the charger from the power source, then:
- Disconnect the charger from the negative pole (black cable) and then from the positive pole (red cable). The order is reversed than when plugging in the charger to charge.
- Connect the wires of the car's on-board network to the battery - first the red cable, then the black cable.
- Start the car and make sure the battery is working properly.
Before disconnecting the charger, you can make sure that the battery has the correct voltage to start the car. When the battery is discharged to 1/10 of its capacity, it will probably only be suitable for disposal or regeneration by a professional company - a rectifier will not be applicable in this case. The same applies to low electrolyte levels. Its absence or inappropriate level will cause a decrease in battery performance and the need to replace it with a new one.
How to connect the charger to the battery - can the battery be charged?
Simply connect the charger to the power source and the battery in the correct order and you will be able to recharge the battery within minutes. This is a convenient way to recharge your car battery a little in the winter when it's exposed to the cold outside. Car batteries should be charged using powerful rectifiers, such as 24 V. For small batteries, such as those found in motorcycles, a 12 V charger is sufficient.
Dead battery on the road - how to start the car?
When the vehicle is in motion or parked for a longer period of time (especially in winter), it may turn out that the battery is significantly discharged. In such a situation, it will be impossible to start the car. Do you want to know how to deal with such a problem? It's simple. Call a friend or a taxi company to help you get a second car with ignition wires. All you have to do is connect the battery of a serviceable vehicle to your vehicle and wait a few or a few minutes. The principle of connection is the same as for the rectifier. The main thing is not to mix up the colors of the wires and do not connect them the other way around. Then you will lead to a short circuit, and this can even disable the car's electrical system. Attention! Never fill up a car by charging one from the other. This causes an increase in electrical voltage on the wires and can damage the wiring in the car.
After starting the car with a cable method, you can disconnect the clamps and move on. If the problem persists, your battery may be dead and need to be replaced with a new one.
How to care for a car battery?
Once you know how to connect the charger to the battery, how to remove the clamps from the battery, and how to charge it on the go, you should also learn how to keep it in good condition at all times. To make it last as long as possible, follow these tips:
- keep car batteries clean
- decide to charge the battery cyclically when the car is parked for a long time,
- do not over-discharge the battery,
- check the car's alternator.
By following these few tips, you will effectively reduce the risk of car battery damage due to over-discharging or operating in extreme high or low temperatures. Also, never charge a battery that is dirty, rusty or leaking. This is the first step towards tragedy! Don't forget to invest only in batteries of recommended manufacturers - this is a guarantee of reliability and efficient operation for many years.
