Batteriets aldring kompenseres i løbet af levetiden med en øget frigivelse af afladningsdybden. I forbindelse med et elektrisk køretøj betyder dette, at køretøjets rækkevidde holdes konstant så længe som muligt i løbet af dets levetid. Først når afladningsdybden har nået 100 %, bliver den anvendelige kapacitet mindre.
