At Big Box Cars, transparency has always been at the heart of what we do — and soon, we’re taking it one step further for our electric and plug-in hybrid customers.
We’re excited to announce that Big Box Cars will soon be partnering with AVILOO, a trusted name in electric vehicle battery diagnostics, to offer free battery health testing on every EV and PHEV we sell. This initiative is designed to give our customers even more insight and confidence when buying an electric or plug-in hybrid vehicle.
Once live, the AVILOO Flash Battery Test will provide a detailed look at the state of a vehicle’s high-voltage battery — the key component in any EV or PHEV. The test is fast, non-invasive, and will produce a clear, easy-to-understand report showing the battery’s current condition and performance compared to factory standards.
Each tested vehicle will also come with a date-stamped AVILOO certificate, giving customers a verified snapshot of the battery’s health.
When buying an electric or plug-in hybrid vehicle, the condition of the battery is just as important as the engine in a petrol or diesel car. However, until now, it’s been difficult for used car buyers to get accurate, independent data on battery health.
By including an AVILOO Flash Test with every EV and PHEV we sell, Big Box Cars is giving customers the transparency and peace of mind they deserve. It’s our way of ensuring you have as much information as possible before making your purchase decision.
When this feature rolls out, the battery health reports will be directly available on the vehicle’s online listing. That means anyone browsing our EV or PHEV stock will be able to see the battery condition at a glance, just like you already see vehicle features, photos, and comments.
Buying an EV or PHEV is a big decision — and the condition of the battery is one of the most important factors to consider. By partnering with AVILOO, we’ll soon be able to provide complete transparency on battery health, giving you peace of mind when choosing your next electric vehicle.
This exciting new feature is coming soon, and we can’t wait to share it with our customers. Keep an eye on our website and social channels for updates — and get ready to shop with more information and confidence than ever before.
