Warning Signs to Look For

Your car may be telling you its battery needs replacing if you've noticed any of the following:

●      Your car is slower to start than usual

●      It takes several attempts to get the engine going

●      Headlights or dashboard lights look dimmer than normal

●      Reduced power to the electrics – think slower windows or a sluggish stereo

●      An illuminated battery warning light on the dashboard

If any of this sounds familiar, it's worth an appointment at a local garage rather than waiting to see if it gets worse. It's also worth having your battery checked once it passes three years old, even if nothing seems wrong yet.

“Most drivers assume that a battery which doesn’t survive winter has been majorly affected by the cold weather, but this is only what kills it off. Extreme heat can accelerate deterioration within older batteries, as the high temperature can speed up the chemical reaction inside, cause water in the electrolyte to evaporate and cause corrosion to the lead grids. You’ll only notice this when the temperature drops.

“As a result, we recommend checking the health of your battery throughout the year, not just at the start of winter, to keep ahead of any potential failures.” - John Rawlins, Marketing Manager at Clarios, the world’s largest car battery supplier & the company that manufacture VARTA

Catching it early, rather than waiting for a battery to fail completely, is often the difference between a routine replacement and being stuck on the driveway. You can make a booking in under 60 seconds, so you can put your battery worries to rest without ringing round garages for quotes.

What's the Difference Between a Battery Repair and a Battery Replacement?

In most cases, a failing car battery isn't repaired, it's replaced.

“Car batteries are sealed units, so unlike a lot of the parts on your car, there's nothing inside for a garage to strip down and fix. Once its cells start to degrade, a replacement is the only way to properly restore full performance” - John Rawlins

The only genuine repair work involved is usually external, such as cleaning corroded terminals, tightening a loose connection or checking the wiring. Even then, this is only worth attempting if the battery itself is still in good health.

Why Does My Car Need a Specific Type of Battery?

Not every car battery is built the same, and fitting the wrong type for your vehicle can cause more problems than it solves.

Most older cars use a standard flooded lead-acid battery (sometime referred to as an SLI Battery, as they predominantly power Starting, Lighting and Ignition), but if your car has Start-Stop technology – where the engine automatically switches off at traffic lights or in queues – it needs a battery built to cope with the extra strain of restarting the engine repeatedly throughout a single journey.

That's where EFB (Enhanced Flooded Battery) and AGM (Absorbed Glass Mat) batteries come in. EFB batteries are designed for entry-level Start-Stop systems, offering more cycling durability than a standard battery.

AGM batteries go a step further: rather than the acid moving freely inside the battery, it's absorbed into glass mats, making the battery more resistant to vibration and better suited to cars with higher electrical demands, such as heated seats, larger infotainment systems or additional safety tech.

It's also tempting to assume all car batteries do the same job, so buying the cheapest one available could be appealing. In reality, the difference between a standard and a premium battery usually comes down to three things: the quality of interior materials used, how well the battery copes with real-world conditions like cold weather or short journeys and how long it's genuinely built to last.

“A low cost battery and a premium battery can look identical from the outside, but the internal construction (the grid design, the plate thickness, the quality of the separators between cells) is what determines whether a battery still starts your car reliably in three years' time or five. That's usually reflected in the warranty length as much as the price tag.

“We always recommend that drivers prioritise the long-term health of their vehicle by choosing quality over cost and fitting the right battery for their car, with VARTA often being the original battery installed when new.” - John Rawlins

How Long Do Car Batteries Last, and How Can You Extend This?

Most car batteries last somewhere between three and five years, though this varies depending on how you drive, where you live and how well the battery's looked after. Frequent short journeys, cold weather and heavy use of in-car electronics all put extra strain on a battery and can shorten its lifespan considerably.

A few habits can help you get the most out of your battery:

●      Take your car on longer journeys occasionally, rather than exclusively short trips, to give the battery a proper chance to recharge.

●      Keep the battery terminals clean and free from corrosion as a quick visual check every few months is enough to catch build-up early.

●      Avoid leaving accessories like interior lights or a dashcam running when the engine's off.

●      If your car sits unused for long periods, consider a trickle charger to keep the battery topped up.

If your battery is coming up to three years old, it's worth having it checked by a garage rather than waiting for it to fail completely.
