Not all 12 volt batteries actually use acid. Lead/acid storage batteries do, however, and in those the acid is generally 4-5 molar sulfuric acid. "How much" acid depends on the volume of the battery ... some batteries are physically larger than others ... but for a rough figure you can assume that somewhere around 30% of the liquid by mass is sulfuric acid.
It's a good idea to avoid charging any battery with a charger that was not designed specifically for that kind of battery. A car (vehicle) charger is generally designed to recharge 12 volt lead acid batteries. (The actual voltage of the battery and charge is a bit higher than 12 volts.) Rechargable battery packs come in different voltages, and many if not most are not lead acid types. A lot are nickel-cadmium or lithium types, and they need a "controlled charge" that a vehicular battery charger will not be able to provide. And that's setting aside the issue of the voltages of the battery and the charger, which is critical.It's a bad idea to attempt to recharge a battery with a charger that is not designed to recharge that "flavor" of energy storage device.
It needs 2 batteries.
No, there are only atoms, electrons and chemicals in a battery. And there are many of these types of things in bigger batteries.

To become dangerous, the source of electricity must be powerful enough to create a current flow through the body, and to do that, the voltage of the source of electricity must be high enough to overcome the electrical resistance of the body. The voltage in most batteries isn't high enough to overcome the electrical resistance, and without that, no dangerous current. There are a few instances where a battery has killed a person, given the right contact points on the body and a low resistance of the person.
Normally there is one lead acid battery in a car.
12 Normal storage batteries use lead acid technology. Lead acid cells have a nominal voltage of 2 volts each. Adding them in series adds all of the cell voltages together.
None, a car battery is lead-acid, not alkaline.
The main environmental concern about lead acid batteries is lead contamination. Many of these car batteries are recycled but some are disposed of incorrectly and each battery contains 18 pounds of lead. This lead could leak into surrounding soil and air thus causing contamination. Lead is extremely toxic for humans and could cause kidney or brain damage.
Sulfuric acid is commonly found in car batteries, as it is used as the electrolyte in lead-acid batteries. It is also used in many industrial processes, such as in the manufacturing of fertilizers, detergents, and pharmaceuticals. Additionally, sulfuric acid is used in the automotive and construction industries for metal cleaning and etching.
UPSs generally contain lead/acid batteries. The worn-out battery should not be disposed of in a landfill or incinerated because lead is harmful to many organisms. Lead batteries recycle well and you can sometimes get money back for them.
Lead-Acid cells are generally considered to deliver 2 volts, so you'd need 24 cells to get 48 volt. Easiest way of doing that would be to use two 24V batteries as used in truck and heavy vehicles.
Solar Batteries come in 3 distinctive types.Flooded lead acid,Gelled lead acid (aka gel batteries),and AGM lead acid (aka AGM batteries).Neither gelled or AGM batteries are designed to leak. However, if a gelled battery is charged in an inverted state, it can leak the electrolyte. An AGM battery never leaks.Flooded batteries however, can pose a problem. When a flooded battery is discharged and frozen, it can burst the container, allowing the acid to spill out as it thaws. This can cause both a environmental spill, and cause corrosion to the electrical equipment surrounding the battery installation.For this and many other reasons, many choose the more efficient, safer, and maintenance free AGM battery design indoors. Even when the inspector doesn't demand it.
It can be many, many things. In the simplest homemade battery it can be water. In a car (lead/acid) battery it is sulfuric acid (H2SO4). Many batteries (AA's, rechargeable batteries, etc.) are dry cells which dont even use a solution (NiMH, Li-ion, Li-po (well kind of in the case of li-po, its a gel), and many others)
A battery energy storage system (BESS) is a technology that stores electrical energy in batteries for later use. It is designed to store excess electricity typically generated by renewable energy sources, such as solar or wind, and to release that electricity when high demand or intermittent generation sources are not available. Batteries used in energy storage systems can be of many types, including lithium-ion, lead-acid, liquid flow batteries, or other emerging technologies. The choice of battery technology depends on specific requirements such as cost-effectiveness, energy capacity, response time and cycle life.
Freezer Storage of BatteriesYour question is difficult to answer because you don't mention the kind/type of battery, or by what you mean by "...work?"Exposing lead-acid automotive batteries to freezing temperatures REDUCES the chemical activity rate and thus reduces the current the battery is able to produce.I don't know about the current "fancy" batteries [Nickel-Cadmium (Ni-Cad), or Nickel-Metal-Hydride (Ni-Mh), or the others whose names I can't think of right now].Back in the "old days" when we used Carbon-Zinc batteriesthere was a widespread rumor that when buying batteries in bulk [ we photographers bought them by the case] that storage in the freezer would extend the "shelf life."So I don't really know for certain BUT... many years ago when I was in the photography business, the common buzz was that if batteries were STORED in the freezer that the SHELF LIFEwould be extended.We all did it regularly, but I used so many batteries so fast that I didn't have enough storage time to be sure whether it worked or not.I "think" that storage of Carbon-Zinc batteries did extend storage life somewhat, but I have no idea regarding the newer/modern batteries. And I don't know if Carbon-Zinc batteries are still available.
That would depend heavily on whether you're talking about wristwatch 'button' batteries, automotive storage batteries, or telephone central office UPS batteries.
