Battery discharge – causes

The battery is an extremely important element of every vehicle, because its task is to accumulate energy while the engine is running and to be a constant source of electricity for the entire electrical system in the car. Typically, the battery charges while driving. However, it happens that when we leave for work in the morning, we try to turn the key, but the car refuses to obey and nothing happens. Alternatively, the indicators do not want to come on or blink, or the lights cannot be turned on. These are signals that the battery may be discharged or too weak. What can cause a discharged car battery?

The causes of battery discharge in a car may be external and internal, related to weather factors, incorrect installation or use of parts, or sometimes the battery is simply defective. The causes of battery discharge in a car during winter are most often low temperatures, which affect its electrical efficiency and ability to start. Self-discharge is more common in summer, so even on hot days you should remember to drive regularly or charge the battery with a charger.

The causes of battery discharge when parked are related to the situation when, after turning off the engine, electrical devices continue to consume electricity. You need to remember to turn off the lights, turn signals, etc. It also happens that damaged equipment or an alarm may consume more energy than it should. Then, even after 24 hours, full discharge may occur. In turn, the reason for the discharge of a new battery may be related to the incorrectly selected battery power for the needs of the car. Other reasons include:

• battery contamination (oil, dust, moisture),
• driving only short distances,
• end of battery life,
• faulty alternator.
• The battery needs to be kept clean, recharged when necessary and regularly inspected to keep it working for a long time and without problems.

Summarized

As you can see, the causes of battery discharge may be different, but the most important thing is to quickly remove the fault so as not to cause major damage to the vehicle. A discharged battery does not always mean that it needs to be replaced, but it is worth remembering that it has an expiry date, after which it is better to buy a new one.
