National standard lead-acid battery with high endurance

What is the design life of a lead acid battery?

Europe took a different tack. The Eurobat Guide for the Specification of Valve Regulated Lead-Acid Stationary Cells and Batteries defines design life as follows: “The design life is the estimated life determined under laboratory conditions, and is quoted at 20°C using the manufacturer’s recommended float voltage conditions.” 6

What does the lead–acid battery standardization Technology Committee do?

The lead–acid battery standardization technology committee is mainly responsible for the National standards of lead–acid batteries in different applications (GB series). It also includes all of lead–acid battery standardization, accessory standards, related equipment standards, Safety standards and environmental standards. 19.1.14.

How is standardization organized for lead–acid batteries for automotive applications?

Standardization for lead–acid batteries for automotive applications is organized by different standardization bodies on different levels. Individual regions are using their own set of documents. The main documents of different regions are presented and the procedures to publish new documents are explained.

Do lead-acid batteries need a special fixation method?

Usually batteries require special internal fixation methods to be able to pass this kind of requirement. Due to the fact that lead–acid batteries contain dilute sulfuric acid as electrolyte, there are several requirements and test procedures to check that no leakage occurs during normal operation.

Why do lead-acid batteries need to be discharged daily?

Diesel-electric power is expensive, so the battery is discharged daily to about 50% DOD. In developed countries, grid stability becomes an issue, especially if much of the electric power is generated by solar or wind energy. As a result, load levelling in distributed sites has become a new challenge for lead-acid batteries.

How reliable is a stationary lead-acid battery?

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.
