Choosing and Replacing Car Batteries: Expert Advice

A car battery is a crucial component, providing power for the starting system, electrical system, and electronic devices in your vehicle. Choosing and replacing the right battery is essential to ensure stable and long-lasting vehicle operation.

Common Types of Car Batteries

Currently, there are three main types of car batteries on the market:

• Flooded Batteries: These use a diluted sulfuric acid solution and require periodic water refills. Advantages include low cost and easy maintenance. Disadvantages are susceptibility to corrosion and shorter lifespan.
• Maintenance-Free (MF) Batteries: These do not require water refills and have a longer lifespan than flooded batteries. Advantages include convenience and minimal maintenance. The disadvantage is a higher price.
• AGM & EFB Batteries: These are specifically designed for vehicles with Start-Stop systems, offering fast charging and discharging capabilities and a very long lifespan. The advantage is superior performance. The disadvantage is a very high price.

When to Replace Your Car Battery?

Here are some signs that your car battery needs replacement:

• Slow Cranking: The engine cranks slowly, struggles to turn over, or requires multiple attempts to start.
• Battery Warning Light: The battery warning light on the dashboard illuminates.
• Weak Horn: The car horn sounds weak or muffled.
• Dim Headlights: Headlights appear dimmer than usual, especially when multiple electrical devices are on.
• Swollen or Leaking Battery: The battery appears swollen, deformed, or shows signs of leaking fluid.
