On 6 April 2026 at 22:53, QZ sent the owner of a Maserati GranTurismo Modena an alert: “The battery is in a serious state.” The voltage had dropped to 11.94 V — the zone where a successful start is no longer guaranteed and the battery begins to suffer permanent damage. All the while, the car sat in its garage and from the outside everything looked fine.
The owner connected a charger that same night — the chart shows the immediate jump. A day and a half later, though, the voltage was falling again and QZ sent a second alert. Two warnings in three days told a clear story: the battery wasn't merely flat, it was reaching the end of its life. Thanks to that, the owner dealt with it calmly and on his own schedule — not in the garage one morning, with the Engine Start/Stop button on the steering wheel giving no response.
This is exactly QZ's job: watching the battery around the clock, understanding its chemistry, and speaking up before it's too late — and only when it really matters.
