Dec. 31, 2014—Tesla Motors is making its battery swap stations available to Model S owners in California, according to recent reports.

The battery swap station will be located opposite a Tesla station between Los Angeles and San Francisco, according to a report from from Forbes. The station enables the company to offer customers the choice of “faster or free,” allowing the customer a choice between a 30-minute recharge or a three-minute battery swap for a fee of $50–$60.

The introduction of a titanium under body cover to prevent damage to car batteries has increased the length of the procedure to around 3 minutes.
