A car battery is an essential component of your vehicle, responsible for providing the necessary power to start the engine. Over time, however, batteries can wear out or fail due to various reasons such as corrosion, damage, or simply old age. If you are looking for car battery service Dubai, this guide will help you make an informed decision.
Clean corrosion from terminals:
- Safety first: Ensure that the vehicle’s ignition is turned off before starting any work on the battery.
- Locate the battery terminals: These are typically found at the top of the battery, marked positive (+) and negative (-).
- Disconnect the cables: Start by disconnecting the negative cable (black) using a wrench, then move on to the positive cable (red). Be cautious not to let the wrenches touch both terminals simultaneously, which could cause sparks.
- Remove corrosion: Using a wire brush dipped in a baking soda solution, scrub away any visible signs of corrosion around the terminal posts. Rinelyse thoroughly with water and dry completely.
- Reattach cables: Beginning with the positive cable, reconnect each cable securely onto their respective terminals. Tighten them gently but firmly using a wrench.
Check water level:
- Identify maintenance-type batteries: Some modern vehicles use sealed AGM or gel cell batteries that don’t require regular water level checks. However, if your vehicle has a traditional lead-acid battery, follow these steps.
- Open the battery cells: Most batteries have removable caps that reveal the individual cells inside. Carefully lift these caps to expose the fluid levels.
- Assess the water level: Each cell should contain enough distilled water to cover the lead plates fully. If the water level is low, proceed to step four; otherwise, replace the caps securely.
- Add distilled water: Top up each cell with distilled water until it reaches just below the bottom of the vent well. Avoid overfilling, as this may cause leakage during operation.
Test battery voltage:
- Obtain a multimeter: This device measures electrical voltage and can be purchased from most auto parts stores or online retailers.
- Set up the multimeter: Switch the meter to read DC volts (denoted by a V with a straight line above it), ideally between 10 and 20 volts.
- Measure the voltage: Touch one probe to the positive terminal and the other to the negative terminal. A healthy battery should register between 12.6 and 13.2 volts when the engine is off.
- Perform a load test: If the voltage drops significantly under load, it indicates that the battery may need replacement soon. You can perform a load test using a specialized tester available at auto shops or rental centers.
