Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
Since the conductivity varies with concentration, this means that the internal resistance of lead–acid batteries changes during charge and discharge processes and is the lowest around the midpoint in the discharge or charge. In the later stages of discharge, when the battery is approaching full discharge, the conductivity decreases and limits the current that the …

The worldwide battery market for lead-acid batteries was around 18.5 billion US$ in 2010 . It is well known that one of the main reasons for a relatively low specific capacity and energy of lead-acid batteries is the low utilization efficiency of the active mass in conjunction with the heavy weight of a conventional grid .
Lighter weight - LiFePO4 batteries are much lighter than lead acid for the same capacity, at only 10 to 20% of the weight. Higher usable capacity - LiFePO4 provides nearly 100% usable capacity, while lead acid is limited to 50% depth of discharge, which is to prevent life reduction.
