Car longevity is of interest to many ... in 2012 the typical car was estimated to last for 200,000 ... at least one battery replacement and eight electric motor ...
It's also reasonable to expect a battery to last longer than that. Tesla's Impact Report for 2022, for example, states that its battery packs only have 12% degradation at 200,000 miles.

A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
When the battery is then used, the majority of the current flows only in this area, and the bottom of the plates tends to wear out rapidly. This is one of the reasons a conventional car battery can be ruined by leaving it stored for a long period and then used and recharged.
The cell is a solid-state battery that maintains constant pressure regardless of charging and discharging rates. The system includes an iso-temperature element. [49] In January 2024, Volkswagen announced that test results of a prototype solid-state battery retained 95% of its capacity after 1000 charges (equivalent to driving 500,000 km). It ...
Zebra batteries can last for a few thousand charge cycles and are nontoxic. The downsides to the Zebra battery include poor specific power (<300 W/kg) and the need to heat the electrolyte to about 270 °C (518 °F), which wastes some energy, presents difficulties in long-term storage of charge, and is potentially a hazard. [39]
The energy density (energy/volume) of a new LFP battery as of 2008 was some 14% lower than that of a new LiCoO 2 battery. [45] Since discharge rate is a percentage of battery capacity, a higher rate can be achieved by using a larger battery (more ampere hours) if low-current batteries must be used.
