Tesla Introduces Li-ion 12-volt Battery in New Model S/X

New details about Tesla’s new Model S and Model X have surfaced and they does not disappoint. According to Tesla CEO Elon Musk, the automaker is ditching the lead-acid battery in exchange for a Li-ion 12-volt car battery.

During its end of year earnings call last week, Tesla finally announced the highly-anticipated new Model S and Model X. With the announcement, the EV giant teased the new refresh adding loads of new information on its website including new battery packs, electric motors, refined exterior design, and brand new interior. However, we didn’t get a full reveal. 

Now, a new detail has surfaced from Tesla CEO Elon Musk himself. Tesla has transitioned the new Model S and Model X to Li-ion 12-volt battery. The 12-volt battery system used in Tesla vehicles is a lot like those found in other vehicles. It is responsible for powering the lights, media unit, windows, etc. However, Tesla has struggled with issues surrounding the battery life of its 12-volt batteries, specifically in the Model S and Model X.

Tesla attempted to fix the battery issues last year with a software update but has now confirmed they have transitioned to a new 12v Li-ion battery in the refreshed Model S and Model X. During a interview with Sandy Munro, Musk stated: “With the new S/X, we are also are finally transitioning to a Li-ion 12-volt battery. It has way more capacity and the cycle life matches the main battery pack. We should have done that before, but it’s great that we are doing it now.”

Deliveries of the new Model S Plaid are expected to begin in February, followed shortly after by the new Model X Plaid. According to Musk, the new tri-motor Model S Plaid will be the first ever production luxury sedan to be able to achieve 0-60mph in just two seconds.
