Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte. ... In other words, if the preventable causes of failure are eliminated, then a battery will last ...
Causal tree analysis for quality control of the lead acid battery ...
The aim of this paper is the quality control of the manufactured lead acid battery by using the causal and fault tree analysis. The causal tree allows the description of the correlations between the battery degradation modes and their causes during the manufacturing process.
Ironically one of the most common reasons for battery failure is not an actual failure of the battery itself, it is people thinking the battery is dead. ... Just because a lead acid battery can no longer power a specific device, does not mean that there is no energy left in the battery. A car battery that won''t start the engine, still has the ...
