Why replace a car battery?

A car battery is an electrical storage unit that allows the vehicle’s electrical system to operate. Systems such as the starter motor, fuel pump, and engine control unit will not run without it. It’s usually a large, box-like device full of electrolyte material and lead plates that work together to become charged whenever the vehicle and its alternator run. It connects to the car through two posts that transfer energy into the vehicle.

Like other car parts, car batteries can fail due to extreme temperatures, corrosion on terminals or cables, or a malfunctioning charging system or alternator. Mechanical issues unrelated to the battery may also drain it or put undue stress on the unit, causing it to fail prematurely. Moreover, car batteries age, and they usually last only five to seven years. 

How would you know if a car’s battery is already failing? Watch out for these warning signs: 

  • The engine is slow to 'turn over' or crank. If it takes a few seconds longer than normal to start the engine, it is probably time to get a car battery replacement. 

  • The 'check engine' indicator lights up. Note that some vehicles have low battery fluid indicators, and no matter what type of indicator your vehicle has, it is an irrefutable sign that you need a new battery. 

  • The physical appearance of the battery indicates a problem. This might be a leak with corrosion on the posts or other build-up on the case. The case itself may look bloated, swollen or cracked.

  • Apparent sulphur smell in the vehicle. This is the smell of corrosion caused by battery acid leaks

  • The battery is past three years in age. This is the ideal time to have it checked in order to see if a truck or car battery replacement is needed

  • Dim lights. The headlights, interior lights and other interior electronics (radio) appear too dim. 

One or more of these issues means it is time to scout out a car battery replacement service. That can mean buying the battery and paying an expert to do the installation or even entrusting them with the task of choosing the best battery and doing the work.

It's important to note that prices may vary depending on the battery's brand, size, and specific features. 

Here's a breakdown of the average costs for car batteries by type of vehicle.

The first thing to know is that vehicles have no universal or ‘one-size-fits-all’ batteries. They are in different sizes and types and may have unique configurations and terminal placement. That is why you will want to consult with a mechanic in order to purchase the right option for your specific vehicle. Keep in mind that changing technologies and advances in vehicle design make batteries more expensive than in the past, along with creating multiple options for any specific vehicle.

You may find that your older vehicle (one over five years old) can use older batteries. However, newer vehicles with specialized electronics may demand a specific type of battery. For instance, cars that shut down when at a full stop require specialized batteries with more complex battery replacement issues. 

The process of replacing a battery generally means:

  1. Obtaining the right battery for the vehicle

  2. Having it installed properly in the vehicle

When done by an expert, they will:

  • Safely remove the old battery by disconnecting the negative cable and the positive.
  • They loosen the tie-down system and remove the battery.
  • The cable ends, and all wiring is inspected and cleaned (they may need replacement if corroded)
  • They will then install the replacement and restore the tie-down system. They may apply anti-corrosion compounds to terminals.
  • They will use the tools to ensure it is done properly if any programming is needed.
  • The vehicle starts, and the charging system’s output is compared against the original equipment manufacturer settings.

Some can offer proper recycling of the old battery as part of their fee. It is important that the charging system and the vehicle’s general operations are back to normal after installation.

What factors might affect the price of a car battery replacement?

As mentioned, a luxury car with battery monitoring equipment and alternators operated through the engine’s control unit or ECU and those with silver calcium can cost far more. However, they typically last longer and are less prone to damage due to temperature extremes.

Additionally, any problems discovered while testing the charging system or related components may increase the total cost of car battery replacement.

FAQs

Absolutely, and if there are problems with wiring components or the battery itself, you may find that a jumpstart will fail to remedy the issue. This is s sure indicator that you need a new battery.

It may surprise you to learn that short trips of 20 minutes or less do not allow the battery a chance to recharge. If you do this for years at a time, the battery may have a much shorter lifespan than one that is in a vehicle driven for an hour or more on a regular basis.

That is possible. Many vehicle owners mistakenly believe that freezing weather is the most difficult for batteries, but it is scorching heat that is a real strain on a battery’s life span. A garage or parking in the shade can only do so much to protect the battery.

It is possible that vibration caused the breakdown of internal parts inside of the battery. This is why you must ensure that there are no missing or loose bolts where the batteries housing is concerned.
