Colloidal batteries (Gel) are a developmental classification of lead-acid batteries by adding a gelling agent to the sulfuric acid to make the sulfuric acid electrolyzed into a colloidal state. A battery in which electro-hydraulic is colloidal is often referred to as a colloidal battery. The difference between colloidal batteries and conventional lead-acid batteries is further developed from the initial understanding of electrolyte gelation to the electrochemical properties of electrolyte substrates and their application in grids and active materials. Its most important feature is: to produce a better battery with a small industrial cost, its discharge curve is straight, the turning point is high, its energy and power are more than 20% larger than conventional lead-acid batteries, and the life is generally conventional lead. The acid battery is about twice as long, and the high temperature and low temperature characteristics are much better. waterproof solar charge controller

36-1.jpgThe colloidal lead-acid battery (Gel) is an improvement of the ordinary lead-acid battery for the liquid electrolyte. The colloidal electrolyte is substituted for the sulfuric acid electrolyte, which is improved compared with the ordinary battery in terms of safety, storage capacity, discharge performance and service life. 20a solar controller

The colloidal lead-acid battery (Gel) adopts a gel electrolyte, and there is no free liquid inside. The electrolyte capacity is large under the same volume, the heat capacity is large, and the heat dissipation ability is strong, which can avoid the thermal runaway phenomenon of the general storage battery; the electrolyte concentration is low, and the electrolyte plate is low. The corrosion effect is weak; the concentration is uniform, and there is no electrolyte stratification. China solar charge controller
