A Grade Point Average (GPA) is a summary statistic that represents a studentâs average performance in their studies over a stated period of time, such as one semester. Being numerical, GPAs are often calculated to two decimals.
What term is used to indicate charged solutions contained in wet cell bateries? Wet cell batteries contain liquids called electrolytes, such as sulfuric acid.. Dry cell batteries contain no liquid but are charged with alkaline or lithium.
VRLA Gel Batteries. A gel battery (gel cell) is a VRLA battery with a gelified electrolyte; the sulfuric acid is mixed with silica fume, which makes the resulting mass gel-like and immobile. Unlike a flooded wet-cell lead-acid battery, these batteries do not need to be kept upright. Gel batteries reduce the electrolyte evaporation, spillage (and subsequent corrosion issues) common to the wet-cell battery, and boast greater resistance to extreme temperatures, shock, and vibration.
