Published 20:11 26 Nov 2024 GMT Tesla owner left stunned after 10-day battery test had a very unexpected outcome The man left his Tesla at the airport for 10 days while he went on vacation Niamh Shackleton Tesla batteries are said to be the best in the world, and this guy's test has proven why. Typically if you leave your car unmoved for a period of time, it can lead to your battery charge decreasing. As to why this happens (despite you not moving it), it's down to a number of factors. Advert For example, if you leave you dashcam plugged in while not using your vehicle, this can drain the battery. Extreme temperatures can also cause your battery to drain quicker. According to UK-based company Auto Exhausts & Tyres, a car with a reasonably new battery that's been well looked after can remain unused for around two weeks before going completely flat. Some make of cars might last up to four months, however. With cars being known to lose a large amount of battery charge in reasonably short periods of time, content creator Everyday Chris decided to put his Tesla to the test when he left it stationary for 10 days at San Francisco airport. Advert In a bid to try maintain as much battery life as possible, Chris disabled the power-draining features like Sentry Mode and Cabin Overheat Protection before leaving the electric vehicle. Using Tesla's nifty app, Chris - who boasts over 93,000 subscribers on YouTube - was able to keep an eye on the car's battery life while he was on vacation. He left the car with 80 percent charge and after 10 days came home to find that it had only dropped one percent. Impressive! Advert People have since shared their reactions to Chris' video. A fellow Tesla owner said: "Parked my Model X for two weeks and had no drain! I was impressed." "I can confirm after being on a trip for five days with no loss," another shared, "BUT why do I have phantom drain up to three percent when parked at work for just eight hours." "The drain is not consistent," they added. Advert
