Thelithium-ion battery has emerged as the most serious contender for dethroning the lead-acid battery. Lithium-ion batteries are on the other end of the energy density scale from lead-acid batteries. They have the highest energy to volume and energy to weight ratio of the major types of secondary battery.
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 potential to provide plenty of fireworks should you short the terminals.
In both flooded lead acid and absorbent glass mat batteries the buckling can cause the active paste that is applied to the plates to shed off, reducing the ability of the plates to discharge and recharge. Acid stratification occurs in flooded lead acid batteries which are never fully recharged.
At the same time the more watery electrolyte at the top half accelerates plate corrosion with similar consequences. When a lead acid battery discharges, the sulfates in the electrolyte attach themselves to the plates. During recharge, the sulfates move back into the acid, but not completely.
uniformity of concentration and maintenance of electrolyte solution. Both sets of parameters will act (to varying degrees) to cause the eventual failure of the battery. The most common failure modes of lead–acid batteries are described in Box 3.1 (v.s.), together with remedies that can be adopted.
All rechargeable batteries degrade over time. Lead acid and sealed lead acid batteries are no exception. The question is, what exactly happens that causes lead acid batteries to die? This article assumes you have an understanding of the internal structure and make up of lead acid batteries.

BatteryStuff Articles | The Lead Acid Battery Explained
One not-so-nice feature of lead acid batteries is that they discharge all by themselves even if not used. A general rule of thumb is a one percent per day rate of self-discharge. This rate increases at high temperatures and decreases at cold temperatures. Don''t forget that your Gold Wing, with a clock, stereo, and CB radio, is never completely turned off. …

Lead–acid battery fundamentals
For many years, it was thought that lead–acid batteries of any type could not be fast charged because there would be irreparable damage to the positive active-material. In the early 1990s, however, researchers at Cominco in Canada showed that a variant of the current-limited CV method, in which a so-called ''resistance-free voltage'' was ...

Why Lead Acid Batteries Are Not Sustainable
Lead-acid batteries are heavy because they contain sizable amounts of naturally dense lead. The average 3 KWh lead acid battery weighs around 66 pounds. It also has the lowest energy density among available battery options. On the other hand, Li-ion batteries are much lighter (approximately 55% lighter than lead).
