How to identify if you need to replace your old battery?

1. The engine lamp turns on

One of the visible symptoms of battery replacement is when the engine lamp gets activated. This specific part of the car acts as an indicator of a drop in voltages. The voltage is associated with the battery, providing car users a knowledge of the current performance of the battery.

2. Failure in the car’s electronics

From headlights to car screens and electrical accessories, the battery is the main source of energy that run these devices. Therefore, if the battery is corroded, these essential parts of the vehicle will not work efficiently. A visible sign of an old battery is dimmer dashboard light or a non-functional computer screen.

2. Location of replacement

Aside from that, you also need to consider the location you are in. For instance, auto parts stores located in rural towns may have limited stocks. Therefore, there could be some waiting game to do the replacement.

However, there are some instances where it’s best to upgrade batteries. In doing so, make sure to confirm it with a mechanic or with a professional.

Along with the technicalities, you also need to consider the price. Gather some estimates from different stores and suppliers and try to evaluate the cheapest option with the best quality.

How to replace a car battery?

Replacing a battery requires time and effort. To make it less stressful, we’ve prepared a list of simple steps that you can easily follow. And before you start, make sure that you find an open ground away from water and fire to do the replacement. Then, engage the break, turn off the car, and take out the key.

You also need to wear safety gear to avoid contact with possible battery acid or harmful buildup. Put on safety goggles and globes. As soon as everything is set, continue with the guidelines below.

  1. Pop the car’s hood or open the location of the battery, depending on the model.
  2. Check the two battery cables―black and red. The black one is generally considered the negative cable while the red cable is the positive terminal.
  3. Disconnect the black cable first to prevent short circuits.
  4. Detach the red cable. During this process, you need a wrench to loosen the cable clamp.
  5. Find the bolted bracket at the bottom of the battery. Take out the wrench again to loosen the bracket and remove the battery carefully. Place the battery on a safe and concrete surface.
  6. Using a rust remover and sandpaper, polish the battery cables to remove dirty residue.
  7. Install the new battery and use a bracket to lock it in place. Afterward, use a wrench to tighten the bolt. You may also add dielectric grease to the two terminals to avoid acidic accumulation and battery corrosion.
  8. Attach the red or positive cable by putting it over the terminal and tightening it via a socket wrench.
  9. Reconnect the black or negative cable next, following the same procedure above.
  10. Lastly, check all the connections and make sure that they are all set up properly. There should be no loose or waggling cables. Once everything is good, close the car’s hood, start up the vehicle, and you’re good to go.


Having a solid understanding of doing basic part replacement is very helpful. It allows you to do the tasks efficiently. More than that, you’d appreciate the savings that you’d get from working on these errands personally. But of course, you have to ready yourself for the labor and the time you need to spend.
