how to check car battery

Checking your car battery's condition in Malaysia is something you can handle with a few straightforward steps. Firstly, inspect the battery for signs of bulging, leakage, or corrosion. These are clear indications that the battery may be nearing the end of its lifespan. If you spot white or greenish gunk around the terminals, a mixture of baking soda and water can be used to gently clean it off. The most accurate way, though, is to use a multimeter to check the voltage. With the engine off, a healthy battery should read between 12.4V and 12.7V. Once you start the engine, that number should jump to a steady 13.7V to 14.7V. If it’s dipping below 12V, your battery probably needs a charge—or maybe even a full replacement. A lot of newer cars will also have a battery warning light on the dashboard. If the light is glowing persistently, do not ignore it; have it inspected as soon as possible. For those without tools, just pay attention to how your car starts. If the vehicle starts slower than usual or the headlights appear dimmer, these are typical signs that the battery is running low. Malaysia’s hot and humid weather isn’t kind to batteries, so they tend to wear out faster here. That’s why it’s smart to get a professional check every 2 - 3 years. For daily maintenance, keep the battery surface clean and dry. If you’re leaving your car parked for a long time, disconnecting the negative terminal can help preserve charge. When it’s time for a new battery, make sure it matches your vehicle’s specs—different cars need different Cold Cranking Amps (CCA). Investing in a quality battery designed to handle tropical climates will pay off with more reliable performance and steady power.
