A hybrid-electric vehicle includes a traction battery. A controller may operate the traction battery within certain state of charge and voltage limits. The controller may define a minimum operating voltage or state of charge below which no power may be requested from the traction battery. The minimum voltage and state of charge may be based on an electrical resistance of the traction battery. The voltage may also be based on a minimum power level required to crank the engine while meeting emissions standards. As the battery ages, the minimum voltage level may be adjusted such that the minimum power level is available at the minimum voltage level.
