Gel batteries can be used for a variety of purposes, such as: communication, power generation, power distribution, remote control and traffic engineering, security power supply, data engineering systems, alarm signals and safety lighting, etc. 1. Using solid gel electrolyte. Under the same volume, the electrolyte capacity is large, the heat capacity is large, and the heat dissipation ability is strong, which can avoid the thermal runaway phenomenon that is easily generated by general batteries. Strong adaptability to ambient temperature (high and low temperature). 2. There is no free liquid inside, and there is no possibility of internal short circuit. 3. The electrolyte concentration is low, and the electrode plate is weakly corroded; the concentration is uniform, and there is no phenomenon of acid stratification. 4. Using antimony-free alloy battery plates, the battery self-discharge rate is extremely low, and the battery does not need to be recharged after two years of storage at 20 degrees Celsius. 5. Using sliding airtight technology. 6. Long-term discharge capacity and strong cyclic discharge capacity. 7. High-sensitivity low-pressure umbrella air valve (patented by the German Sunshine Company) is adopted, and there is no seepage or swelling phenomenon. 8. Super strong ability to withstand deep discharge and high current discharge, with self-protection over charge and over discharge. Gel battery is a closed valve-regulated lead-acid rechargeable battery that fixes the electrolyte in the gel.
