Electric vehicles come with some obvious perks, from impressive acceleration and near-silent driving to charging costs that are typically, though not always, lower than fueling up with gas. But there’s a flipside when things go wrong. Battery replacement isn’t just expensive, it can easily eclipse the value of the car itself.

Just ask the owner of this 2013 Tesla Model S, for example, now staring down a quote that’s far from reasonable.

Watch: Tesla Model S Cruises Past 430,000 Miles On Original Battery

This particular owner recently visited a Tesla service center in Madison, Wisconsin, to get estimates on a battery replacement. According to a post they shared on Reddit, they inquired about swapping out the existing 60 kWh pack for either the same model or a larger 90 kWh version. Both options came back with steep price tags that likely outstrip the resale value of the vehicle.

Battery Pricing Hits Hard

A replacement 60 kWh pack would cost $13,830. That includes $580.50 for labor, based on a 2.58-hour installation time. The rest, a hefty $13,250, covers just the battery itself. Not exactly light on the wallet for what is now Tesla’s smallest available battery on offer.

The price jumps significantly for the larger 90 kWh pack. The pack alone costs $18,000, with an additional $4,500 required to unlock its full capacity. Factor in installation and necessary replacement parts, and the total comes to $23,262.

That’s well beyond what most used Model S vehicles from the same year are currently worth. We found they typically range from $10,000 to $15,000, depending on trim and condition. From a financial standpoint, the upgrade cost doesn’t pencil out.

Reddit user u/sirromnek shared the experience, sparking discussion among other Tesla owners. While many have logged hundreds of thousands of miles on their original packs without issue, battery degradation isn’t unheard of. For some, the only path forward is a costly replacement.

While going directly to Tesla is an option, new batteries can also be purchased from third-party suppliers, often at a much lower price than Tesla offers. However, given that decade-old Tesla Model S sedans are barely fetching over $12,000, buying a replacement pack probably isn’t worth it.

It looks like Tesla’s found itself with a problem of abundance. The automaker has more cars sitting on lots across the United States than it seems to know what to do with. And with the federal EV tax credit gone, sales have slowed considerably.

To keep things moving, Tesla has decided to do something a little different, by renting out its own cars directly to customers, starting at two locations in California, with more likely on the way.

The company recently confirmed that its stores in San Diego and Costa Mesa are now offering rentals from the entire Tesla lineup.

What Does It Cost?

If you’ve been curious about living with a Model 3 or Model Y, you can now take one home for as little as $60 per day. The Cybertruck, perhaps the most talked-about of the bunch, is listed at $75 per day, while the more premium Model S and Model X command $90 per day.

Of course, no deal from Tesla would be complete without some important caveats. For starters, cars must be rented for a minimum of three days and a maximum of seven days.

Furthermore, while renters will be able to enjoy unlimited mileage, they will not be permitted to drive the Tesla out of the state. They’ll also be hit with a $30 fee if the car is returned with less than 50 percent charge.

There’s no word on whether the advertised rates include insurance, or if Tesla, like traditional car rental companies, will try to sting shoppers with exorbitant insurance fees.

What we do know is that only the upper-tier Premium trims are being offered. The entry-level Standard versions aren’t part of the deal, and neither are the high-performance Performance or Plaid variants.

Tesla will no doubt hope that by offering cheap rentals, it can convince interested shoppers to place an order. To help further convince them, they’ll receive a $250 credit if they place an order within seven days of the rental.
