There can be several costs to consider when maintaining a car, including replacing car batteries. Although there are many options available regarding car batteries, there are several factors to consider before purchasing a car battery.

The following is an overview of the checks that can be made before purchasing a new car battery and guidance regarding fitting a new battery.

Ensure the Battery is Dead

The battery is responsible for a series of car tasks, including the car's ignition. Many will assume the battery needs replacing when the power fails, but this isn’t always the case. It can be worthwhile checking the connections and that there are no frayed wires.

There may also be instances when vehicle owners can recharge the car battery, although the charging method depends on the type of battery.

Recharging Car Batteries

There can be a lot of confusion about whether a car battery should be replaced or recharged. The older a car battery is, the less likely it will hold its charge. Vehicle owners should seek a replacement if the battery is over five years old, as the charge is unlikely to hold.

However, if you have recently purchased a car battery but find the car is unable to start, then a recharge may be all that is needed. The approach taken regarding charging will depend on the type of battery.

Those using calcium and lead-based batteries can use a conventional battery charge that can be found when browning motor specialist stores. Many brands are available, but as with car batteries, the charger you choose must be reliable and safe to use.

If you own a vehicle with start-stop technology, then you will need to purchase a smart charger. Each will have its own set of instructions depending on your car. Those unsure of what charger to purchase should check with the car manufacturer directly, as using the worn charger could create faults with the vehicle.

Those charging lead and calcium batteries should try to remove the battery beforehand. The battery will still charge if not removed, but it does mean the car is exposed to other hazards, and the battery may not reach a full charge. Removing the battery ensures you can charge completely without exposing the car's interior to the elements.

The time it takes for a car battery to reach full charge averages between 10 and 24 hours. If there is still no charge following this time, the battery is defective and will need to be replaced.

What Type of Battery Do You Need?

Understandably, some assume all batteries are the same, but this is not the case. There are three common types of batteries which are as follows.

Lead Acid Car Batteries

Lead acid batteries are the most common, meaning they’re also the most affordable. Car owners are often guaranteed a number of starts, averaging 20,000. However, each manufacturer will have its own guarantees, so car owners should check these before buying the car battery.

Calcium Car Batteries

Calcium car batteries offer more starts than lead acid alternatives and are ideal for those struggling to start their vehicles on cold mornings. Calcium car batteries cost more than lead acid car batteries but can be seen as the better investment as they offer an improved service in addition to more starts and longer guarantees.

Absorbed Glass Mat/Enhanced Flooded Batteries

Cars with start-stop technology will require an AGM or EFB battery. Both battery types are more expensive than lead and calcium batteries but generally offer more longevity. For an AGM or EFB battery to be fully effective, it may need to be aligned with the vehicle’s onboard computer.

How Long Should a Car Battery Last?

Car batteries have an average lifespan of five years, but there are many factors to consider when deciding the best time to replace the battery. The more features a car has, the more power it will consume. Similarly, those who regularly drive often find they replace their battery sooner than moderate drivers.

Vehicle owners can buy batteries via a series of motor stores and online, but choosing a battery recognised for quality is essential. A low price is all good and well, but if it affects the quality of the battery, then the low cost can be a false economy and could end up costing car owners more in the long term.

If you’re keen to ensure your battery is retaining charge, then investing in a dedicated car battery tester may be worthwhile for peace of mind.

Changing a Car Battery

When a car battery needs changing, vehicle owners can use several methods. Some may prefer to enlist the services of a professional to ensure they receive the correct battery and it is fitted correctly.

However, those choosing to replace and fit their own battery must carry out a series of steps to ensure they find the correct battery for their vehicle and fit it without difficulty.

Check for Codes on the Battery

One of the easiest ways of sourcing a replacement battery is to use the codes listed on the battery. If no code can be found, then some additional checks will need to be made to ensure you purchase the correct battery, including the following.

Check the Dimensions

No two batteries are the same, so it is essential to check the divisions of a car battery before making a purchase. The dimensions of the battery are crucial, as the fit will be tight and secure to ensure the vehicle remains safe.

Choose the Right Voltage

In addition to different dimensions of car batteries, there are also different voltages to consider. Modern vehicles will often require a higher voltage battery than older models because of the many tasks required, including air conditioning and navigation.

If you still have difficulty sourcing the correct car battery or charger, reaching out to a professional can be worthwhile. Several online tools can aid car owners in finding the correct battery for their cars by entering some simple details.

Taking some time to check the correct battery is purchased from a reliable manufacturer ensures that you find value and longevity in equal measures,
