how to choose car batteries by model

Thinking of switching your car battery but don't know where to start with all the choices on the market? You're in luck, because this blog post has all the essential information you need about how to choose a car battery by model.

Car Battery Model Factors

Deciding on the most fitting car battery to buy can be difficult, especially if you are doing it for the first time without professional knowledge. Battery models can differ vastly from each other, with each one featuring a unique construction, design, and specifications.

Of course, with the various makes and models of cars also being built very differently from one another, it’s essential to find a vehicle battery that can give you and your car what you need, whether that’s better performance or longevity.

Here at Orius Batteries, we know how confusing it can get, so we are here to lend customers a hand when it comes to decisions like these. Below are four important factors to consider when choosing car battery by model in the UK.

  • Cold Cranking Amps (CCA)

    This measures the battery's ability to start an engine in relatively low temperatures. The CCA number you’ll find in your vehicle’s manual gives you the minimum rating you need. You’re advised to buy a battery with a higher rating than this, especially if you keep or drive your car in colder regions of the UK.

  • Battery Size

    Different car battery models come in different sizes, so you need to check carefully that you’re buying a battery that will fit perfectly in your vehicle’s battery tray. So, before you settle on which one to buy, refer to your car’s manual to find out which battery group size you should be looking for. You can also simply measure your vehicle’s battery tray yourself, and then compare it to the measurements of the one you’re thinking of buying.

  • Reserve Capacity (RC)

    Another thing that sets car battery models apart from each other is their Reserve Capacity (RC) rating. Also known as a battery’s “standing power”, the RC refers to the number of minutes a battery can continue powering your car if the alternator fails.

    It’s worth noting that every car comes with a recommended RC rating range. Consult your owner’s manual to make sure you’re buying a battery with the appropriate specs for your car.

  • Special Features

    Some modern vehicle batteries come with special features or technology that offers different advantages. If you want the best battery for your car, it’s worth keeping this in mind.

    Some features to look out for are silver calcium technology, which offers better charge voltage tolerance and power, and absorbent glass mat technology, which is ideal for start/stop vehicles. You can also choose low-maintenance or maintenance-free batteries for less hassle when caring for your car.

where to choose car batteries by model online


Are car batteries specific to each car?

Not necessarily. Car batteries can differ in some respects but still work with different car makes and models. The important thing is that the specifications are compatible. It’s therefore important to choose car batteries by model of car, to make sure you’re getting something that works with your vehicle’s power requirements.

What happens if you use the wrong sized battery in a car?

If you fit an over- or undersized vehicle battery into your tray, this may lead to problems. Most manufacturers are fairly precise about the physical dimensions of the batteries needed for each car, and also about the specifications required to make it run smoothly. Make sure you buy a battery that’s of compatible dimensions and the required specifications.

What is a good CCA rating for a car battery?

It’s not enough to select an automobile battery by design alone. You must also consider the right CCA rating, which depends on your car’s minimum requirements and the kinds of places you drive. Often, an average of 650 CCA on car batteries is enough to withstand cold weather. But for more extreme conditions, a battery with 800 CCA is recommended.

How long can a car battery last without driving?

On average, a car battery can retain its charge for two months or longer without the engine ever running. But this depends on the battery and your car, as well as how both were stored. To keep your car battery lasting for longer, make sure you run or charge it regularly and carry out proper maintenance.

How often should you change your car battery?

Ideally, you should replace your battery around every four to five years. The battery’s lifespan, though, depends on various factors. You can buy a longer-lasting unit, as long as you carefully get your automotive battery by version, brand, and type.

Warning Signs Of A Failing Battery

Just like the rest of your car’s parts, the battery isn’t designed to last forever. Here are some signs that your battery is failing:

  • There’s a build-up of residue on the battery’s terminals.
  • There’s a battery warning light flashing on the dashboard.
  • The engine has a hard time starting, especially in the mornings.
  • Your car’s lights start to flicker during a drive.

Factors To Consider When Buying A Replacement Car Battery

Here are the different factors to consider when picking a vehicle battery by type:

  • Age of the car. Make sure you take the age of your car into account. When you decide to buy a new one, select one that’s the right size, and with specifications that match your vehicle.
  • Climate conditions. There are batteries that are more resistant to cold weather than others. If you live in colder climates, it’s best to go for an AGM or gel battery.
  • Start-stop system. You should consider whether or not your car has a start-stop system when shopping for a new car battery. Start-stop cars often have much greater power requirements than those without this technology, and so need an adequately robust battery to match.

Keeping Your Battery In Good Condition

  • Keep it clean. By keeping your battery clean, especially the terminals, you can prevent corrosion and improve the way it holds a charge.
  • Always turn the electrics off. Don’t put too much strain on your car battery and always turn the electrics off when not in use.
  • Consider distance. Always consider how charged your car battery is before taking long trips. If your battery discharges while you’re out, you may need to jump-start it. Make sure you choose a car battery jump starter by model from a reputable seller before heading out on long journeys.

These are just a few tips car owners need to keep in mind when choosing a new battery. If you have any specific enquires, feel free to contact the team at Orius Batteries today!
