When you use your battery, the process happens in reverse, as the opposite chemical reaction generates the batteries’ electricity. In unsealed lead acid batteries, periodically, you’ll have to open up the battery and top it off with distilled water to ensure the electrolyte solution remains at the proper concentration.
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.
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.
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.
If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly discharged to below 50%. In flooded lead acid batteries this can cause plates to touch each other and lead to an electrical short.
As routine maintenance, you should always check the battery electrolyte levels and ensure that the battery cells are always covered. Sealed and valve-regulated lead-acid batteries are designed in such a way that the gases released from the electrolysis of water in the electrolyte, recombine back to form water. 3. Thermal Runaway

According to Battery University, keeping a battery operating at a low charge (below 80%) can lead to stratification, where the electrolyte "concentrates on the bottom, causing the upper half of the cell to be acid-poor." This can affect the overall performance of the battery and eventually lead to failure.

The lead–acid battery came to the world 10 years too early because, at first, it had to be charged with Bunsen and Daniell cells. At the Breguet Company in 1873, Planté met the Belgian engineer Zénobe Théophile Gramme (1826–1901) who built direct-current generators (1869–71) that were based on Pacinotti''s ring armature (1860). Planté recognized that his own …

Lead-Acid Battery Basics
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions ...

How bad is it to undervoltage a 12-volt lead-acid battery?
$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.
