In a flooded lead-acid battery, much of the gases generated will escape from the battery. This is essentially water escaping in form of gases thus causing the acid levels to go down. In sealed and valve-regulated lead-acid batteries, the gases are in a contained environment where it is not easy to escape but recombine back to water.

If there is visible corrosion on the terminals or elsewhere on the battery, it''s likely that the battery is damaged beyond repair and will need to be replaced.
Get PriceA battery acid specific gravity is defined as "the ratio of the density of the battery acid, relative to water with which it would combine if mixed evenly" A standard solution is defined as "a solution that contains some number of grams of solute per liter of solvent." The battery acid is made up of sulfuric acid that is diluted with water.
Get PricePutting it simply, a completely depleted ''dead'' lead acid battery will freeze at 32°F (0°C). When a lead acid battery is fully discharged, the electrolyte inside is more like water so it will freeze". (Jump down to chart) What happens when a lead acid battery electrolyte physically freezes?

Depends on the battery type what bad can happen, but generally that doesn''t include harm to the battery -- it includes danger of acid leaks. ...
Get PriceA car battery is a lead-acid battery, and as such it uses a chemical reaction between lead and sulfuric acid to create the electrical current that powers your car. Over time, this reaction causes the water in the battery to evaporate, and if it isn''t replaced, the battery will eventually fail.
Get PriceThis made it possible to easily recharge lead-acid batteries, and so they spread out across the planet. Since then, the technology that''s inside lead-acid batteries advanced by leaps and bounds, and continues to be one of the most important, and widely used battery technologies.

Get PriceAGM batteries, or Absorbent Glass Mat batteries, are a type of lead-acid battery that offer several advantages over traditional flooded lead-acid batteries. AGM batteries are sealed, maintenance-free, and have a longer lifespan than flooded batteries. ... In this article, we will discuss what happens when an AGM battery is deeply discharged ...
Get PriceIf 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 …
Get PriceElectrolyte also comes in a polymer, as used in the solid-state battery, solid ceramic and molten salts, as in the sodium-sulfur battery. Lead Acid. Lead acid uses sulfuric acid. When charging, the acid becomes denser as lead oxide (PbO 2) forms on the positive plate, and then turns to almost water when fully discharged. The specific gravity …
Get PricePure lead is too soft to use as a grid material so in general the lead is hardened by the addition of 4 – 6% antimony. However, during the operation of the battery the antinomy dissolves and migrates to the …
Get PriceFirst a little background information: Good Battery. A good battery will sit around 12.6 to 12.8 volts when fully charged. When a good battery is put through a load test equal to its rated CCA (cold cranking amps) its voltage will drop to around 9.6 to 10.5 volts depending on the ambient temperature.
Get PriceJust wondering what will happen to the battery if it falls below 10V. Is it still rechargeable, or is a new battery required? ... If it accepts and keeps a charge, it''s still functional. In general, lead-acid batteries are quite tame and forgiving when it comes to over-discharging (and also, to a limited extend, over-charging).
Get PriceIf you have a large lead-acid car battery and you drop it in a swimming pool full of saltwater, it will produce hydrogen gas for up to two weeks. ... Another possibility is that nothing will happen at all. The car battery may be sealed so tightly that it can''t come into contact with water, and so it doesn''t get damaged or start a fire.
