Specific Gravity For Nicad Battery

Nickel–cadmium battery - Wikipedia

Vented cell (wet cell, flooded cell) NiCd batteries are used when large capacities and high discharge rates are required. Traditional NiCd batteries are of the sealed type, which means that charge gas is normally recombined and they release no gas unless severely overcharged or a fault develops. Unlike typical NiCd cells, which are sealed, vented cells have a vent or low pressure release valvethat releases any generated oxygen and hydrogen gases when overcharged or discharged rapidly. Since the battery is n…

Aircraft Batteries | Aircraft Systems

Aircraft batteries are used for many functions. Most small private aircraft use lead-acid batteries, commercial and corporate aircraft use nickel-cadmium (NiCd) batteries. Two types of battery used are lead-acid and NiCd batteries. Dry charged cell lead-acid batteries, also known as flooded or wet batteries, Valve-regulated lead-acid batteries (VRLA) cells have a pressure relief safety valve.

For those of you who store your batteries or let them sit without use, be aware that a process called "sulfation" occurs if the battery’s specific gravity falls below 1.225 or below 12.4 volts. Sulfation is actually a hardening of the battery’s internal plates which need to remain soft and porous so that acid can flow through them.
