Electrical components receive their energy from the battery to serve us. Without a powerful battery, these components will function uncontrollably or even remain off. From this fact, we can come up with another answer for how to tell if your car battery is dead by conducting tests on the normal activity of electrical components.

The most obvious and effortless parts you should focus on are the radio, the electrical-control seats, and the AC.

#5 Slide Up And Down The Electrical Lateral Windows

The lateral windows operating on electricity are also worth checking when you ask yourself, “Is my battery dead?”. Since the fuse and motor of the electrical windows in old cars sometimes stop working, owners may assume the problem comes from these parts.

However, you should spend a little more time looking at the battery to ensure that it’s still in good condition. The malfunction of electrical lateral windows shows up when you slide it up or down, but the windows move slowly with hindrance.

#6 Listen To The Engine Sound While Turning It Up

Noticing the clicking sound can be the answer to your question, “Is my battery dying?”

#7 Timing The Engine Crank

With a full battery, you don’t have to use much time to crank up an engine. Yet, when the battery runs out, it’s a different story. The engine of a car with an empty battery will require you to transfer a little gas into it to generate efficient power for the car.

This is a tell-tale method based on drivers’ experience to tell how to know if the car battery is dying.


#8 Check The Battery Connectors Condition

Suppose your car keeps dying even when you have performed some check-ups and replacements. The problem may not lie in the battery itself. Sometimes, they are connectors and terminals that cause the malfunction of the battery.

After a long use time, the battery will release acid that corrodes the metal terminals and connectors. Consequently, the corroded metal parts won’t recharge the battery and transfer its energy throughout the vehicle. Even though you can fix the damaged components yourself, we suggest buying new parts for more durable and reliable use.

#9 Examine The Battery Case Condition

In the event of a scorching temperature or overcharge, the battery will become swollen. This is the most dangerous situation among all of these battery conditions.

When swollen, the battery is like a bomb, and it can go off anywhere if you don’t handle it properly. For this reason, whenever you notice a swollen battery case, you must call for help from a professional mechanic.

The common life of a brand-new battery will vary from four to five years. If you haven’t done any test on the battery within this time, you can see the reasons for the car battery to die. It has run out of fuel.
