1. Solve electrolyte stratification, sulfuric acid evenly distributed. 2. The silica gel electrolyte lead-acid batteries can be so deep discharged, thus greatly extending the cycle life of the battery. 3. The battery float current is small (about 1/3 AGM battery), the floating charge lower energy consumption, less warming, and reduces battery thermal runaway risk. 4. low self-discharge rate of the battery.
