This resulted in a 20-year, 10-year, or possibly other stated design life. In Europe, design life is applied to components used in the battery and the limiting factors that might affect lifetime as established from endurance 3. Endurance values are the result of combining standardized and accelerated testing results.
IEEE 450 and 1188 prescribe best industry practices for maintaining a lead-acid stationary battery to optimize life to 80% of rated capacity. Thus it is fair to state that the definition for reliability of a stationary lead-acid battery is that it is able to deliver at least 80% of its rated capacity.
And warranty is in fact only a guarantee against manufacturing defect. A warranty statement can only assure a user that if he follows accepted and documented maintenance practices as outlined by the manufacturer, the battery (or cell) is warranted against manufacturing defect for a specific period of time.
It is accepted industry practice that a battery is considered “good” or reliable as long as it can deliver ≥80% of its rated capacity 1. IEEE 450 and 1188 prescribe best industry practices for maintaining a lead-acid stationary battery to optimize life to 80% of rated capacity.
