The fundamental elements of the lead–acid battery were set in place over 150 years ago 1859, Gaston Planté was the first to report that a useful discharge current could be drawn from a pair of lead plates that had been immersed in sulfuric acid and subjected to a charging current, see Figure 13.1.Later, Camille Fauré proposed the concept of the pasted plate.
Sealed Lead Acid batteries fall under the category of rechargeable batteries and if they are ignored, not charged after use, not charged properly or have reached the end of their intended life span, they are done.. In ideal circumstances an SLA battery should never be discharged by more than 50%, for a maximum life span no more than 30% (to a 70% state of
