However, Akkuauto Finland Oy has studied the Model 3 batteries and developed repair methods, and can now repair them just like the Model S/X batteries. The Model 3 batteries are improved versions of the Model S/X batteries in many ways, but one fundamental issue remains, and the newer battery also has new challenges.
