Battery recharging: how long and how to do

The start -up cables allow two cars to be connected to recharge a low battery . Just position a second vehicle remotely enough to be able to make the battery battery connection, then run the engine of the second vehicle . This generally provides the energy necessary for the vehicle “broken down” to be able to launch the engine. A certain time will be necessary to provide the necessary energy. Once the engine is started, driving will correctly recharge the battery .

How to recharge the battery of a car ?

Even if it seems “fit”, a battery can discharge for various reasons. Prolonged parking, strong temperature variations or forgetting to turn off its headlights cause progressive energy loss. If that were to happen, it is not always useful to replace the battery. Simple recharging most of the time allows to remedy the problem. How to do it ?

You have cables ? It’s time to get them out

The start -up cables allow two cars to be connected to recharge a low battery . Just position a second vehicle remotely enough to be able to make the battery battery connection, then run the engine of the second vehicle . This generally provides the energy necessary for the vehicle “broken down” to be able to launch the engine. A certain time will be necessary to provide the necessary energy. Once the engine is started, driving will correctly recharge the battery .

At home, use a battery charger

The battery charger is a classic. Operating on a 220 volts socket, it is not nomadic and must be connected to home . Very easy to use, just connect the positive and negative battery terminals, then turn it on so that the load starts . Depending on the state of the battery to be recharged and the power of the charger, a certain time will sometimes be necessary for a complete recharge (sometimes an entire night).

Good to know: disconnect or disassemble the battery before recharging it

To avoid a possible short circuit, it is advisable to dismantle or disconnect the battery before connecting it to the charger. Remember to use a data backup device if you have one.

The battery starter (also called booster): nomad or not

Battery starters are widespread and there are all kinds. This goes from the big booster that connects to the 220 volts and allows in a few seconds to revitalize a discharged battery, at the nomadic starter operating using a battery. These devices are equipped with cables that directly connect to the battery to bring a power source powerful enough to start a car .

Be careful, however, to choose the model corresponding to your vehicle, because there are several types and at all prices. For diesel engines, prefer a more efficient model with a more powerful battery. Also remember to recharge it from time to time . Even if the batteries of these devices are increasingly efficient, they end up unloading after a long period of non -use.

For some time we have also seen appear in the trade of very compact “mini booster” that have been stored everywhere. They have the shape of a small battery and recharge via a USB socket . Their powers vary depending on the model, but they are very effective in invigorating a tired battery.

However, you should choose a model whose power is compatible with your engine . Thanks to the different connections available, they also allow to recharge a mobile phone, or even a computer.

Be vigilant during connection

If the latest generation accessories have a protection device in the event of the poles inversion, this is not necessarily the case for the older models. It is therefore important to respect the polarity at the time of connection . These devices being standardized, the red cable is intended for the positive terminal (+), while the black cable will connect to the negative terminal (-) . If in doubt, know that the positive terminal of the battery is the largest of the two.

Before replacing a battery that seems to show signs of weakness, start by recharging it. This is generally enough to put it back in shape. On the other hand, if the problem persists, it will be better to replace it.

⚡ How to recharge a car battery ?

The battery of your car allows to start up via the starter and also feeds all the elements electric or electronic. The battery of your car also feeds other functions of your vehicle:

• The rise and descent of the electric windows;
• Activation of wipers;
• The horn;
• Start -up and maintenance of radio;
• Door locking;
• The ignition of all the lighthouses of the vehicle.

Your battery is made up of two electrodes + and – which bathe in electrolyte (sulfuric acid). THE fluent is issued in the battery with the connection of terminals + and – where the electrons move from – to the +

There recharge of your battery is carried out when the alternator is connected because the electrons move in the opposite direction, from the + to the -. This reaction allows the liquid to recharge in electrons. The battery does not recharge itself when your engine is turned off. It also loses its energy in the event of a long time of non-use of a vehicle.

⏱️ How long to recharge a car battery ?

The time required for recharge a car battery depends on several factors, such as the battery discharge statement, battery capacity, charger charger current used and other variables. In general, here are some approximate estimates:

• Recharge by driving : When you drive your car, the alternator generally recharges the battery. Complete battery recharge by driving can take on average about 20 minutes. However, this may vary depending on the duration of driving, speed, driving conditions and battery status;
• Recharge with a battery charger : The recharging time with a battery charger depends on the charging current provided by the charger and the capacity of the battery. As a rule, for a discharged battery, it takes several hours of recharge. Current battery chargers can take 6 to 12 hours to completely recharge a car battery. However, faster chargers can reduce this charging time.

It is important to follow the recommendations of the manufacturer of the charger and the battery to obtain more precise information on the recharge time specific to your situation. In addition, it is essential to respect the safety instructions when recharging the battery to avoid any potential risk.

��️ What are the symptoms of a battery to recharge ?

Several signals are there to alert you in case you suspect your battery of being down. These are the following:

1. THEbattery lightlights up : Present on the dashboard, it is yellow, orange or red (depending on vehicles) and informs you that there is a problem with your battery;
2. A foul odor comes fromhood : these are sulfuric acid clearances.

4. The headlights lose power : they illuminate less effectively or even go out completely;
5. The horn is broken down : it is triggered only very weakly or not at all.

The abnormal voltage of your battery can be explained if you leave the air conditioning or the radio long on when the engine does not run.

This is also the case during sudden weather change in temperatures: the cold reduces battery performance while the hot will have the battery liquid evaporates. A battery recharge is possible if it is flat and shows these symptoms. But some cases will be necessary to make its pure and simple change.

�� How to recharge a car battery while driving ?

Your battery recharges naturally When your car rolls thanks to the current produced by the alternator and its belt system.

Rolling your vehicle is therefore important to avoid a complete battery discharge, especially during cold seasons such as fall or winter.

When starting your car, the battery recharges using the engine running. Count a full battery recharge while driving 20 minutes. It’s necessary lengthen this period If your vehicle has been immobilized for a long time or the outside temperature is very cold or very hot.

However if your car does not start at all, you will have to recharge the battery with A charger dedicated After having disconnected and removed from the vehicle.
