LAST CHECK’S MOBILE EV BATTERY TEST
An investigation by the Australian Automobile Association (AAA) in August 2025 revealed that five popular electric vehicle (EV) models in Australia delivered between 5% and 23% less driving range in real-world conditions compared to their official laboratory-tested figures.
The assessment, conducted on a 93-kilometre circuit in Geelong, Victoria, found that models from BYD, Tesla, and Kia underperformed, while the Smart #3 EV recorded the closest result to its lab rating.
The findings underscore the significant gap between controlled laboratory testing and everyday driving conditions, where actual ranges are typically shorter.
Using state-of-the-art technology developed by Aviloo in Europe, we provide an independent assessment of an electric vehicle’s battery, delivering buyers and owners a clear understanding of its true condition and actual driving range.
We provide a Mobile EV Battery Assessment for your convenience, visiting you at your preferred location to assess your vehicle and deliver a certified report.
DO NOT FULLY TRUST THE MANUFACTURER’S ASSESSMENT
Manufacturers often exaggerate the health of electric vehicle batteries and their driving range. The ECU is programmed to present everything as normal, so the dashboard typically shows a perfect reading even when the battery has already degraded. At Last Check, we go beyond these surface displays by connecting directly to the vehicle’s ECU and examining the battery at a much deeper level.
Our testing reads the data from the battery management system and assesses each individual cell one by one, giving the most accurate and independent measure of the battery’s true state of health.
In many cases, particularly with some Chinese-built Teslas and several Korean EVs, we have seen dashboards reporting 100% battery health, while our cell-by-cell assessment revealed the figure was already below 95% so its is always best to know what you are actually buying rather than trusting what you see.
EXPECT LESS DRIVING RANGE THAN ADVERTISED
Most electric vehicles deliver far less driving range than advertised, a fact confirmed by worldwide studies and investigations by the Australian Automobile Association. Laboratory figures often exaggerate performance, while real-world driving tells a different story.
Beyond assessing the battery’s state of health, our advanced testing also uncovers the vehicle’s True Driving Range, giving buyers and owners an accurate picture of what to expect on the road.
WHAT YOU GET IN THE REPORT
Last Check’s advanced EV battery test provides an accurate, independent assessment of your vehicle’s true condition. By reading the battery directly through the ECU and analysing each cell individually, we uncover details hidden from the manufacturer’s display.
State of Health (SOH) – The battery’s overall health and usable capacity
Battery Rating – Independent score of the battery’s current performance
Real Driving Range – The accurate distance your EV can travel in real-world conditions
Dead Cell Detection – Identification of failing or weak cells within the battery pack
Battery Control Unit Performance – Assessment of the ECU’s accuracy and reliability
Battery Temperature – Monitoring of operating temperatures for safety and efficiency
Early Signs of Battery Degradation – Detection of subtle performance losses before major issues occur
END OF WARRANTY EV BATTERY HEALTH TEST
In many cases, we have witnessed manufacturers refusing to replace EV batteries unless they are completely dead. Their diagnostic tools are often tuned to show the battery as healthy, even when serious issues exist. Not all brands follow this practice, but some go to great lengths to avoid costly replacements, even if the state of health has fallen below 70% or dead cells are detected inside.
That’s why our End of Warranty EV Battery Health Test is one of the most popular services we provide. It ensures you know the true condition of your battery before the warranty runs out, giving you the evidence needed to secure repairs or replacement under warranty, and potentially saving you thousands of dollars in future costs.
MOBILE PRE PURCHASE EV BATTERY HEALTH TEST
Our Mobile Pre-Purchase EV Battery Health Test is one of the most popular services we provide. It gives buyers complete peace of mind by confirming that the battery is truly in the condition claimed by the seller.
Since EV batteries are usually hidden beneath the seats and cannot be visually inspected, buyers face the risk of unknowingly purchasing a vehicle with a degraded battery, essentially a lemon.
With our advanced diagnostic tools, we reveal the battery’s true state of health and driving range before you commit to buying. Best of all, this test is fully mobile, we come to you, wherever you are, making the process convenient, independent, and reliable.
