Useful tips: how to properly charge the car battery

When it is necessary to charge a car battery? Remove the battery to charge or do not want? At what temperature do this? Motorists often asked many questions regarding the characteristics of charging starter batteries. This is due to the fact that not every motorist is well versed in electricity, and the market is now offering a variety of battery types, maintenance and charging of which have their own characteristics.

If we look at the main types of batteries, all batteries used in transport can be divided into three large groups: maintenance, low-maintenance, maintenance-free. The earliest were serviced, they were used lattice made of lead alloy with the addition of antimony, the advanced —completely maintenance-free, they have used lead grids of maximally pure alloy without impurities. Please note that freedom from maintenance in this case —is no need for refilling of water into the battery during the whole period of its operation. And, contrary to popular misconception among motorists, much of a difference in the the process of charging the three types of batteries have not.

Let's take a closer look at a few topical issues that Ukrainian drivers are asked quite often and give answers to them.

It is necessary to charge a car battery or not?

In order to evaluate the current state of the battery have a simple way. This will require a voltmeter, with the help of this device is measured by the voltage on the battery terminals, disconnect it from the on-board network of the vehicle does not should be. If the battery is in good working order and charged, the voltage should be at the level of 12,6 - 12,7 In. Before measurements, note that it takes a few hours after stopping the engine, otherwise the performance at the time of measurement may be slightly overestimated.

The served by low-maintenance batteries, which are on top of the special plugs that give access to the insides of the batteries, you can check an indicator such as density of the electrolyte. Here you will need a special device —hydrometer. In charged battery density should be 1.27 g/cm ³. If the density is lower in the battery should be recharged. If the density is higher than normal, it is likely that such a power supply needs topping up.

Battery device against the generator, a version of charge optimally

?

Under ideal conditions, no battery charger does not is required, since it is normally able to be charged and to recover from the generator. Experts believe that a charge from the generator, which occurs at a constant voltage, the most useful and safe

.

But the charger you need to restore the battery, which is already low. When this charge is conducted at a constant current. This is important in order to avoid boiling and overcharging. All charging device cease to work when the battery voltage reaches 14,4 In. Some devices then pass into storage mode in which the recharging is carried small currents. Such a regime often does not give a 100% charge.

There is another important feature when using a battery charger, it produces a specific current level set by the user or a specific algorithm of the device itself. But when charging from the generator battery incorporates only the current that is needed. That is why the charge from the generator is better perceived by the battery. However, this is not always enough if you make a strong discharge of the battery, then restore it can be difficult without the charger.

Can I charge the battery in a frost?

We all know from physics that the lower the outdoor temperature, the worse the battery regains its charge. For optimal charging best temperature within from 0 to + 25 ° C. therefore very often the car batteries do not have time during the drive to recover from the generator in winter. If your battery is discharged, then recharge it outside in sub-zero temperatures can not. It is ineffective and may even be harmful. In such a situation it is necessary to place the battery in a heated room with a temperature of the air is greater than zero. Then you have to wait until the battery heats up, only then you can start charging.

It should be Is removed batteries with car to charging

?

No, the battery need not be removed, it is a simple reassurance. Although in theory during charging may occur actively outgassing, which may cause the battery explosion. Not to just a few rules to be obeyed had a problem: I do not to smoke near the rechargeable battery and ensure that the terminals were not short-circuit

How to properly charge the battery when the machine is operated infrequently?

Many motorists often leave their vehicles in the and laid them on a little ride. In such situations it is often used chargers, batteries are constantly feed a small current, thus maintaining 100 percent charged. This is not very useful for batteries, as in these conditions increases the speed of the storage lattice corrosion, which reduces the service life of the battery. Experts recommend for machines that stand without moving for more than 3 weeks, classical way to recharge the battery —from the generator when the engine is started, or by charger. A before you again to send a car for long term storage, the battery should be charged at 100%, otherwise it may be deep discharge, which will lead to the fact that the car just stops start. In the worst case, the battery is completely out of order and would have to buy a new one.

What is the voltage level indicates chronic undercharging?

When the voltage at the battery terminals below 12.3 can be observed in the problem with starting the engine, especially in winter. And if the battery will be a long time in this state, then to restore it will have to spend a certain time. charge would need to conduct a current of not more than 1 A at a constant voltage. Then gradually the current can be increased. In fact, recovery may not always be successful, all will depend on the particular power source. So do not start or exacerbate the problem. Battery charge level should be checked regularly, especially in the fall as winter approaches.

When the voltage drops below 10,5 In this speaks of a very deep battery discharge. If the discharge occurred rapidly, the reduction may be performed in a standard mode, using the memory and the current level of 10% of the rated capacity of the battery. On the charge it will take about 10-12 hours. If the battery was dying slowly due to chronic undercharging, it is necessary to restore the small currents. Similarly to the previous embodiment discussed.

You can Do light a &rbattery from another car

?

Booster a very popular method of motor starting with a dead battery, which is very often used by our motorists. Although there is a perception that it is quite dangerous. However, we can say for sure that Booster. It will be safe under simple rules: the positive terminal of the donor and the acceptor must be connected to each other, while the negatively charged donor conclusion should be mounted on the back of the car that you are trying to start
