8 signs that it's time to buy a new car battery
The battery is an important part of a car and is often overlooked. Many of us need to change our batteries without warning and can cause a lot of inconvenience at unexpected times. Pay attention to these 8 telltale signs and you can quickly guess if your car battery needs replacing. Since the battery is already installed inside the engine bay, we should only perform tests that can be performed under the same conditions. Most users are familiar with this procedure.
8 signs that won't start when it's time to replace a new car battery
Do not start the engine or start slowly with multiple attempts
evidence of sulphation accumulation open the lid and check the terminals for corrosion or evidence of sulphation buildup (white residue near the terminals)
Corroded terminals or connectors - also check cable integrity
Inflated battery case - check if the container is bulging or damaged in any way. If no damage is visible, clean the area, reconnect it and try to start the engine. If starting is still slow, the battery is nearing the end of its life and needs to be replaced.
Dim lights, weak horn or other electrical problems. Turn on the light and see if the brightness goes down within 2 minutes. The current can be measured with a clamp ammeter. If the current gradually decreases, it means the battery is nearing the end of its life.
Excessive heat, as well as too much acid building up in your car battery, can cause its shell to swell and crack. If you notice that your car battery is not a straight rectangle, it's time to replace it.
Bad smell from the battery
An old battery. If 2-3 years have passed after installing the battery, consider a replacement. (Tropical condition)
What factors affect battery life?
Many factors can affect the life of a car battery. The most common culprits are hot temperatures, faulty charging systems, and accumulation of dirt and rust.
In hot climates, car batteries last. This is because they are more chemically active at higher temperatures, increasing the risk of damaging its internal structure. In addition, at high temperatures, the liquid inside a wet battery is more volatile, increasing its acidity.
A faulty charging system can also cause a car battery to drain prematurely and shorten its life. The most common risk factor is a faulty alternator that doesn't provide enough voltage or keep the charging circuit running even when the car's engine is turned off.
Finally, dirt, grease, and rust can make the circuitry around the battery less efficient and limit current, causing car batteries to work harder and die prematurely.
