How is the battery checked? Can you do it yourself? What is required for verification? How reliable is such a check? The answers to these questions are provided through the Used Cars website.

Let’s start in order, as this issue is a bit more complicated, and we’ll also give advice on how to extend battery life.

Do not wait for the battery to die

It’s not just a problem that one morning when you’re going to have a problem starting the car. The problem is that the battery can cause you the same problem several times during the winter. At the same time, its lifespan is shortened as a result.

So, if you pay proper attention to the battery, not only will it be a problem for you that winter, but it will last at least a year or two longer.

In any case, do not wait for it to be completely “dead”, to the point where there is no chance of recovery or when there is no point in replenishing it, as it will cancel again very soon.

What are the signs that something is wrong with the battery?

Apart from the obvious problem when the battery can not start the engine, these symptoms warn of trouble:

– increase difficulty

– Flicker on the instrument panel when the vehicle is switched on

– restart the radio

There are several other “signs” that should not be ignored, but the battery should be checked first:

• Unusual behavior of the cabin lighting when the engine is switched on (eg flickering, short switch-off, etc.)

• problems in the operation of various equipment using el. energy – e.g. window regulators, especially when the engine is off!

• difficult start-up of the engine after the car has been idle for a long time, even without low temperatures

• etc.

If you only need to turn on the car with cables, something is definitely wrong with either the car or the battery, no matter how low the temperature was.

Of course, if you left the headlights on a parked (off) car, that’s a different story. Or if you turned off the music on a picnic or forest on May 1, and you still have a slightly stronger sound system, and only later realize the music draws more “electricity” from the battery than you thought.

Maybe something else “pulled out the electricity”, but regardless of the cause, it is recommended that after such an “incident”, check the battery in the service and recharge it.

It’s not a huge expense, and it can save you a lot of money, time, and nerves. Especially, if only the headlights were on while the car was turned off, this was a problem, then charging the battery on the charger will significantly extend its life.

But if something else is a problem – that problem must be found and solved as soon as possible. Drivers often completely “discharge” the battery several times during the winter when temperatures are low. They think they just have to push through after warmer days and then everything will work out.

When the engine does not want to start, we usually call someone and solve the problem using ignition or push cables, which should be strictly avoided in newer cars.

We spoke to experts from the “Battery Center” of Zemun. One of the main questions was – how do I know that the battery has definitely come to an end?

The answer is that it can only be determined reliably in a specialized service. If the battery can not start the engine even after ten hours of charging, it means that it is most likely time to replace it, of course, if the charger is ready.

We also asked if the driver could check the battery himself. Self-control is possible using unimer, by measuring the voltage.

The battery should be checked every three, six or nine months – depending on driving conditions. This applies to both the warranty period and the warranty period.

Measuring the voltage with a classic unimer can not show us the complete condition of the battery, as the voltage is only one of the factors.

Voltage measurement is not a 100% reliable method, but it can still indicate that, for example:

1) less than 10.5 volts: the battery is defective or deeply discharged (check the car)

2) 12 to 12.4 volts: empty battery (battery needs to be recharged)

3) 12.6 to 12.8 volts: the battery is good

4) above 13 volts – dry and defective battery (must check the car)

However, if you want to be as safe as possible in the condition of the battery, it is best to leave it to a specialized battery service.

There are quick tests that are about 50% reliable (often free), and in addition to testing the battery itself, it should mostly (at least) check the power outage on the vehicle, check the alternator and pull the include the starter.

Of course, what all these checks will be done and how reliable the results will be – of course depends on the service. So inquire by phone first, and specialized services are the best choice.

There is also a great battery service, which is 100% reliable – ask for details at a service center.

In general, if the battery has suffered any damage, it is assessed whether the damage can be repaired.

Self loading

You can also charge the battery yourself – both preventively and when it is discharged. There are many chargers on the market. From very inexpensive that have only basic features, to high quality and intelligent with protection against overcharging, gender reassignment, with charge control depending on the condition of the battery itself and the level to which it is charging, etc.

Generally, the general rule is to charge the battery up to 10% of its capacity. This means, for example, that a 4.5 amp charger charges a 45Ah battery in ten hours.

Generally, if you drive a little or drive mostly short distances, you can significantly extend the life of your battery by recharging it occasionally. But we remind you that if you have a slightly more modern car, you must first get acquainted with the appropriate and safe way to charge the battery – for example. most manufacturers say the battery needs to be removed from the vehicle if it is to be charged.

There is also the problem of losing stored data after several systems lost power of the battery when it is removed. Basically it is not a big problem, you just need to know what and how to do it, how to avoid possible problems or fix when the charged battery is brought back to the car.

Many useful information can be found in the car owner’s manual.
