Car thieves are stealing a new high-tech target by Susie Poppick @FortuneMagazine May 20, 2015, 11:33 AM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons Hybrid cars are increasingly the target of theft, thanks to lightweight batteries that are easy to steal—at least for thieves who know what they’re doing. Toyota Prius drivers in San Francisco seem to be getting the worst of it, a California ABC affiliate reports, with several thefts across the city in recent months. Though there’s a serious risk of electrocution, thieves in the area have succeeded in quickly cutting cables attached to the 200-volt batteries, then removing them within about 20 minutes. Prius batteries can go for as much as $1,000 on Craigslist, a tidy profit given the speed of the job. Unfortunately for Prius drivers, replacing a stolen battery can cost about $3,000—and once you account for the cost of other repairs, like replacing broken windows, the final bill could be as high as $10,000. Buying a used battery online might be cheaper, but then you can’t be sure of just how used it is (or whether it was come by honestly). Despite the risks involved, what makes the theft relatively easy is portability: The battery in the Prius weighs only about 150 pounds. Compare that to the Tesla Model S battery, which weighs more than 1,000 pounds. If you own a Prius, there are a few steps you can take to prevent theft, including replacing the bolts fastening down your battery with tamper-proof ones.
