Before completing its cycle, a car battery shows some signs that it is nearing the end of its life. It essentially prepares us to replace it to avoid unpleasant surprises.
Now in winter changing the car battery is a common occurrence.
White, green or blue oxidation on the battery terminals means reduced performance
One of the most well-known “symptoms” of a battery that has completed its cycle is the inability to start the engine. This happens mainly on cold winter days when, on the one hand, the battery power is reduced and on the other hand, the needs to start an engine are increased.
If you notice difficulty or problems in the ignition when trying to start the engine, then you should visit an automotive electrician to check the battery.
Don't ignore the special red light
If the warning light on the instrument panel comes on (red light with the shape of the battery) then there is a problem with the electronics or the battery connection.
In the cold, battery power decreases and engine starting needs increase, exacerbating the condition of an already worn battery
This can be not only because the battery voltage is low, but it can be loose wires at the terminals, corrosion in the battery, or a problem with the alternator.
If you notice that the headlights of the car have reduced intensity or even flicker or go out, then the problem is easily noticed.
Oxidation at the poles
If you open the hood of the car and see the battery has white, green or blue oxidation on its poles, then you should know that the battery has reduced performance. First of all we clean the poles.
Corrosion occurs when battery acid comes into contact with the outer metal parts of the battery, causing it to overcharge or discharge.
Also, when there is a strange and bad smell, it is very likely due to the condition of the battery. This indicates that the battery is dead or about to die.
If you look at the battery, you may notice some bumps or bulges. This means that there are problems inside it, which may be caused by either overcharging or low temperatures.
Finally, the age of the battery is definitely an indicator of its wear and tear. Given that a battery lasts from 3 to 5 years when we have passed this period or exceeded it, then we should be prepared for a replacement.
