No one can deny the fact that a car battery is one of the most important parts of a vehicle, not least because the vehicle won't even start without it, unless you jump-start it from another working vehicle, which isn't exactly convenient. But why would you buy a car battery while your current one is still working?
To use as a spare or replacement battery
We've established that car batteries are hugely important. Your car won't start without one, and many of the vehicle's most important tools and accessories are powered by it as well. You can just imagine the inconvenience if your current battery dies on you unexpectedly.
This is why it's highly recommended to start thinking about buying a spare car battery once your current one has been in use for around three years. Although most manufacturers state that their batteries should last between three and five years, that lifespan depends on how far and often you drive; how much you use additional electronic accessories; and how good you are at keeping on top of its overall maintenance.
So at what stage should you start looking to buy a car battery online?
If you know a lot about cars, then you'll know it's not wise to store an unused battery for long periods of time. A battery begins deteriorating the moment it leaves the production line. So you can't buy one years in advance if you want to get your money's worth out of it. But equally, you can't afford to wait until it's too late to get a new car battery, either.
To stay on the safe side, make sure you monitor your existing battery's performance so you'll know when it's time to start thinking about a new one. If it always takes a few tries before your car starts, for example, then it's probably time to have your batteries checked. Any sulphurous smell from under the bonnet or disfigurement of the battery casing would also be tell-tale signs that a replacement may be necessary.
To use as a second battery
Remember that your car's standard electrical system was built for your car's standard features. That means that if you've added a number of upgrades, then you might also want to check whether you need a second battery to power up these additional extras.
Let's say, for example, that you notice your headlights dimming each time your stereo setup hits those pounding bass notes. This means that your battery is having a hard time keeping up with all the electronics strapped onto it.
If you can add up how much energy your additional electronics are using, then that makes the decision easier. If you know for a fact that you're using over 1500 watts, then a second battery is probably a good idea.
Of course, there is a proper way of setting up a second battery so don't attempt to DIY it if you're not sure what you're doing. One wrong move in setting up a second battery and you could sacrifice not just your car's performance, but your safety as well.
Always consult a battery expert and ask them for recommendations. They know their batteries well, so can suggest the right way to install a second one and distribute the amount of energy being used by each.

FREQUENTLY ASKED QUESTIONS
How do I know what battery to buy for my car?
Before you buy car batteries, first check your vehicle's user manual for the battery requirements in terms of cold cranking amps (CCA), reserve capacity (RC), and size. However, if you don’t have the manual to hand, check the current battery's specifications and look for one similar to it online.
Can I buy any car battery for my car?
No, you can't. Your vehicle has particular battery requirements, so you must buy a battery that will match those. For instance, you need one that’s the right dimensions to fit in the car’s battery tray, because batteries come in different sizes. What’s more, car manufacturers base batteries on specific models and engine types, so any new battery must match those specifications too.
When should you buy a new car battery?
Ideally, you’ll buy a vehicle battery replacement before your existing one reaches the three-year mark. However, you might have to purchase one sooner than that, or you may have longer, depending on the climate where you live and your driving habits. That's why it’s important to check the battery’s health from time to time.
What is important when buying a car battery?
- Age: When you buy an auto battery, make sure it's less than three months older than its manufacturing date.
- Size: Car batteries aren’t universal, so you need to know the right dimensions to find one suitable for your vehicle.
- Cost: You can buy a cheap one provided it matches your car's battery requirements.
Can you just recharge a car battery?
If you want to recharge a drained battery, first jump-start it. Then charge it fully by taking the vehicle for a long drive or using a battery charger to do the job. If neither of these work, you’ll have to purchase an automobile battery to replace the old one.
How To Choose A Car Battery
Keep the following in mind:
- Ampere Hour Capacity:If your vehicle's user manual isn't available, you can usually find this information on your current battery's label. It's best to buy one with a 10% capacity or more.
- CCA: This is the highest current a battery can produce when starting in minus temperatures. It's fine to buy a battery with a higher CCA, but not a lower one.
- Maintenance: Opt for a maintenance-free battery where possible for less checking.
How to Buy a Battery for Your Car
Vehicles have specific requirements in terms of size, cold cranking amps, reserve capacity, and cell type, so you need a battery that matches those. Find out these specifications from your owner's manual, the current battery, or by looking up your car's make and model online.
Then choose what brand and length of warranty you want. It's best to opt for a high-grade battery with a lengthy warranty coverage from a well-known brand, if you can afford it.

You should get your battery checked regularly. Every time you have your vehicle serviced, ask the mechanic to test its battery. You can also do that yourself by using a multimeter.
