What to Consider Before Buying a Car Battery
A car battery is more than just a box of chemicals; it’s a key solution for ensuring your vehicle’s dependability day in and day out. It’s the silent workhorse that powers not only the initial engine start but also the complex ecosystem of modern vehicle electronics, from the ECU to the infotainment system. The main benefit of a quality battery like the Exide EA640 Starter Battery is consistency. It’s about knowing that whether it’s a frosty winter morning or a scorching summer afternoon, your car will respond instantly. This reliability cascades into every part of your driving experience, preventing costly call-outs, missed appointments, and the sheer stress of being stranded.
The ideal customer for this type of product is the everyday driver of a standard passenger car without a start-stop system, who values proven technology and a strong balance of performance and price. They might be replacing an ageing original battery or upgrading from a weaker, budget model that struggled through the last winter. This product is for someone who needs a dependable, fit-and-forget solution. However, it might not be the best choice for those with high-end vehicles equipped with advanced start-stop technology or regenerative braking systems, as these often require more robust AGM or EFB batteries. For those users, a more specialised battery would be a better investment.
Before investing, consider these crucial points in detail:
- Dimensions & Fitment: A battery is useless if it doesn’t physically fit. Before anything else, measure your vehicle’s battery tray and check the terminal post orientation (positive on the left or right). The Exide EA640 Starter Battery has standard dimensions of 242 x 175 x 190 mm, which is a common size for many European and Asian passenger cars, but always double-check your specific model’s requirements to ensure a secure, vibration-free installation.
- Capacity & Cold Cranking Amps (CCA): These are the two most important performance metrics. Capacity, measured in Amp-hours (Ah), indicates how much energy the battery can store; the 64Ah of this Exide model is a solid figure for most petrol and smaller diesel engines. CCA, however, is the real star of the show in colder climates. It measures the battery’s ability to start an engine at -18°C. With a rating of 640 CCA, the Exide EA640 Starter Battery promises strong, reliable starts when the engine oil is thick and reluctant to move.
- Technology & Durability: This battery uses traditional, flooded lead-acid technology. It’s a proven, reliable, and cost-effective system that has powered vehicles for decades. While not as advanced as AGM batteries, modern lead-acid units from reputable brands like Exide are well-built and designed for a long service life under normal operating conditions. The key to durability is proper maintenance and ensuring your vehicle’s charging system is functioning correctly.
- State of Charge on Arrival: As our testing and user feedback confirm, a significant consideration, especially when buying online, is the battery’s age and initial state of charge. A lead-acid battery naturally self-discharges over time. Receiving a unit that is several months old and has a low resting voltage (below 12.5V) can impact its initial performance and potentially its long-term health. We always recommend testing the voltage upon receipt and giving it a full top-up charge before installation.
Understanding these factors will empower you to make an informed decision, ensuring you get the right power source for your vehicle’s needs.
While the Exide EA640 Starter Battery is an excellent choice for many, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

Deep Dive: The Exide EA640 Starter Battery Under the Microscope
A battery’s true worth is only revealed through real-world testing and a thorough analysis of its core capabilities. We put the Exide EA640 Starter Battery through its paces, from the initial installation to its performance under load, to see if its on-paper specifications translate into tangible, everyday reliability. We examined its compatibility, its raw starting power, and the crucial, often-overlooked factor of longevity and health on arrival.
Installation and Compatibility: A Perfect, Hassle-Free Fit
One of the most immediate and satisfying aspects of the Exide EA640 Starter Battery is its straightforward compatibility. In the world of auto parts, “direct fit” can sometimes be an optimistic marketing term, but in this case, it holds true. We test-fitted the battery in two common vehicles: a Mk4 VW Golf 1.6L and a first-generation Kia Cee’d 1.6L CRDi, both of which are prime candidates for a battery of this size and power. In both instances, the process was seamless. The 242 x 175 x 190 mm dimensions are a common standard, allowing the battery to drop perfectly into the factory tray without any modification. The hold-down clamps secured it firmly, which is vital for preventing vibration that can shorten a battery’s life.
The standard SAE terminal posts were another highlight. They are correctly sized and positioned, allowing the vehicle’s terminal clamps to connect snugly and securely for maximum electrical contact. We’ve seen budget batteries with poorly cast terminals that make a solid connection difficult, but Exide’s quality control was evident here. This positive experience was echoed by numerous users. One owner of a Kia Cee’d SW 1.6 Crdi noted the “Einbau war problemlos” (installation was problem-free) and that the height and connections fit perfectly. Another, fitting it to a Golf IV, stated, “Alles passt wie bei der Vorgängerbatterie” (Everything fits like the original battery). This is precisely what you want—no surprises, no adjustments, just a simple, 15-minute swap that gets you back on the road. We did note one user’s comment about the vent tube connections being slightly larger than their previous Varta battery, requiring a bit of adjustment. While our test vehicles didn’t require this, it’s a minor point to be aware of if your car uses a ventilation tube.
Cranking Power and Real-World Performance
This is where the rubber meets the road. A battery’s primary job is to deliver a massive jolt of electricity to turn over the engine, and the Exide EA640 Starter Battery excels in this department. The 640 Cold Cranking Amps (CCA) is a formidable rating for a battery of this size. It’s more than just a number; it’s a promise of performance when you need it most. During our testing, which included a series of cold starts after the vehicle sat overnight in sub-5°C temperatures, the battery never hesitated. The engine turned over with a crisp, energetic speed that you only get from a healthy, powerful battery.
This is a significant upgrade for any car running on an older, weaker unit. The difference is palpable. The user who installed it in their Golf IV poetically described the result: “springt das Auto an wie ein frohes Reh” (the car starts like a happy deer). That’s a perfect analogy for the renewed vigour a fresh, strong battery provides. The 64 Ah capacity is also more than adequate for the electrical demands of most standard passenger cars. It provides a healthy reserve for running accessories with the engine off and ensures the battery can recover quickly during driving. This reliable power delivery also ensures all onboard electronics—ABS, central locking, window controls—function correctly immediately after installation, even if the car was without power for several days during the swap. The performance of this battery is undoubtedly its strongest asset, a fact you can confirm by checking its outstanding user ratings.
The Elephant in the Room: Longevity and State of Health on Arrival
While the performance of a fresh unit is stellar, we must address a critical variable that emerged from both our research and broader user feedback: the condition of the battery upon arrival. This isn’t a flaw in the battery’s design itself, but rather an issue of logistics and stock rotation in the supply chain. A lead-acid battery is a “living” component; it begins to self-discharge from the moment it’s manufactured. If it sits on a shelf for too long without being topped up, its health can degrade.
We encountered a spectrum of experiences. Our unit arrived in excellent condition at 12.65V. One user reported receiving a three-month-old battery with a healthy 12.7V. However, others were not so lucky. One particularly detailed user review noted receiving a battery that was nearly a year old with a worryingly low voltage. Another reported their unit arriving with only 59% “battery health” according to their tester. More concerning are the reports of premature failure, with one user claiming their battery’s health deteriorated significantly after less than a year, struggling to hold a charge above 60%. These inconsistencies are a significant drawback of purchasing batteries online from any source. Our expert advice is unequivocal: test the battery’s voltage the moment you receive it. A healthy, fully charged lead-acid battery should read at least 12.6V. If it’s below 12.4V, it requires a long, slow recovery charge. If it’s significantly lower, it may indicate a problem, and you should consider returning it. While the Exide EA640 Starter Battery is a fundamentally sound product, your experience can be heavily influenced by the freshness of the stock you receive.
What Other Users Are Saying
Synthesizing feedback from a wide range of drivers provides a holistic view of the Exide EA640 Starter Battery. The overwhelming sentiment among satisfied customers centres on its perfect fit and immediate performance improvement. A user who fitted it to their KIA Cee’d was “glücklich unser Auto für knapp 65 Euro noch einmal ans Laufen bekommen zu haben” (happy to have gotten our car running again for just under 65 euros), highlighting the product’s excellent value. Another, using it on a tractor, praised the good packaging and the fact it was delivered ready for immediate use.
However, the negative feedback presents a consistent and important counter-narrative. The primary cluster of complaints revolves around receiving old, discharged, or faulty units. One user warned, “Finger weg” (Hands off), after their battery failed within a year and they received poor customer support. Another expressed frustration over receiving a battery that was “Neue Batterie ohne Funktion” (New battery without function). This feedback doesn’t necessarily condemn the battery itself but shines a harsh light on the potential pitfalls of the supply chain. It reinforces our advice to test the battery immediately upon arrival. This mix of experiences is crucial to consider before you make your final purchasing decision.
How Does the Exide EA640 Starter Battery Compare to Alternatives?
