While electric vehicles have been proven to have considerably lower ownership costs compared to their ICE counterparts, battery longevity remains an equivocal subject. Similar to how consumers ask how long the batteries can last, manufacturers often question the same subject. ''Every single battery is going to degrade every time you charge and discharge it,'' Atlis Motor Vehicles CEO, Mark Hanchett, told InsideEVs.

While many factors are at play, there are four main elements that assist in further degrading EV batteries.
