A method for measuring fitness for use of a storage battery subject to electric loading including determining a load profile (current profile I(t) or power profile P(t)) as a function of time t, for the storage battery, recording an actual voltage response U(t) of the storage battery to the load profile or calculating a voltage response U(t) of the storage battery to the load profile, and determining a fitness for use value SOH for the storage battery based on the difference between a lowest (highest) voltage value Umin (Umax) during application of the load profile to the storage battery, and based on a voltage limiting value U1, wherein U1 is a voltage value which may not be undershot (overshot) by the voltage U(t) at any time t during which the load profile is applied to the storage battery.
