What is a lead acid battery?
The lead acid battery works well at cold temperatures and is superior to lithium-ion when operating in sub-zero conditions. Lead acid batteries can be divided into two main classes: vented lead acid batteries (spillable) and valve regulated lead acid (VRLA) batteries (sealed or non-spillable). 2. Vented Lead Acid Batteries
What happens if you use a lead acid battery?
Acid burns to the face and eyes comprise about 50% of injuries related to the use of lead acid batteries. The remaining injuries were mostly due to lifting or dropping batteries as they are quite heavy. Lead acid batteries are usually filled with an electrolyte solution containing sulphuric acid.
What is a flooded lead acid battery?
2. Vented Lead Acid Batteries Vented lead acid batteries are commonly called “flooded”, “spillable” or “wet cell” batteries because of their conspicuous use of liquid electrolyte (Figure 2). These batteries have a negative and a positive terminal on their top or sides along with vent caps on their top.
What is a valve regulated lead acid battery?
3. Valve Regulated Lead Acid Batteries (VRLA) Valve regulated lead acid (VRLA) batteries, also known as “sealed lead acid (SLA)”, “gel cell”, or “maintenance free” batteries, are low maintenance rechargeable sealed lead acid batteries. They limit inflow and outflow of gas to the cell, thus the term “valve regulated”.
What is a nickel hydrogen battery?
The nickel–hydrogen battery combines the positive nickel electrode of a nickel–cadmium battery and the negative electrode, including the catalyst and gas diffusion elements, of a fuel cell. During discharge, hydrogen contained in the pressure vessel is oxidized into water while the nickel oxyhydroxide electrode is reduced to nickel hydroxide.
Are lead acid batteries flammable?
Vented lead acid batteries vent little or no gas during discharge. However, when they are being charged, they can produce explosive mixtures of hydrogen (H2) and oxygen (O2) gases, which often contain a mist of sulphuric acid. Hydrogen gas is colorless, odorless, lighter than air and highly flammable.

Why are Li-Ion battery so much safer than lead-acid?
If you tip over the battery, the acid may spill out and do a lot of damage. Also, when charging, lead-acid batteries produce hydrogen. Gel cell batteries usually have some way of containing it inside the battery (and a pressure relief valve), but car batteries do not, since they are usually outside anyway.

Lead–acid battery
OverviewStratificationHistoryElectrochemistryMeasuring the charge levelVoltages for common usageConstructionApplications
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery. Eventually the mixture will again reach uniform composition by diffusion, but this is a very slow process. Repeated cycles of partial charging and discharging will increase stratification of the electrolyte, reducing the capaci…
