Replacing Tesla Model 3 Battery Just Got Cheaper

Batteries do not last forever, no matter how good they are or what they might be powering.  So it is to be expected that they will eventually need to be replaced, which is sometimes an expensive undertaking.  And in the case of an electric car?  You might expect to pay $20,000 or more to replace the entire Tesla Model 3 battery. 

But it seems like Tesla CEO Elon Musk is expecting a lower price tag– only $5,000-$7,000 per battery module.

Tesla Model 3 Battery

The Tesla Model 3 was specifically manufactured to allow for the replacement of separate modules instead of the entire pack, which included the BMS and all of the other electronics attached to it.  As such, it contains four separate, replaceable battery modules.

Considering that the batteries are intended to last 300,000 to 500,000 miles (480,000-800,000 km) depending on the battery version, those price estimates are really not bad.  That is the equivalent of 1,500 cycles. 

Tesla Longevity Claims

Tesla is pretty new to the car manufacturing scene, so it remains to be seen just now long their electric batteries can last and any accompanying replacement or refurbishing costs there may be.  But it seems like Tesla is determined to build cars that endure. 

The previous tweet states that the Model 3 “is designed like a commercial truck for a million mile life”.  Another tweet posted last year purportedly shows the Model 3 drive system after 1 million miles worth of testing, and those gears look pretty darned good.

Tesla Strives for Battery Supremacy

It is no secret that Tesla has an eye on electricity storage– they have been working tirelessly on improving their batteries for years, both for powering cars and the grid in general. Its Powerpack grid projects in places like Hawaii and South Australia are ion-battery wonders.  On a smaller scale, the Tesla Powerwall stores solar-generated electricity for the later use of private consumers.  Tesla has pushed for years to improve their battery technology; part of this push included the acquisition of Maxwell Technologies earlier this year.  This means consumers should be able to look forward to better and cheaper batteries in the future. 

All batteries will eventually degrade over time.  Tesla currently offers an 8-year/100k mile (160,000 km) warranty on the Model 3, whichever comes first.  They also offer a guarantee that the battery in the Tesla Model 3 will maintain a minimum 70% retention of battery capacity over the warranty period.
