Not only will they out perform the competition, they will last longer and provide you improved charging profiles, save both money and time. Dont wait any longer, power up with Joy new technology.Main technical indexes and working environment 1. Design life≥20 years 2. Long cycle life. 80% deep discharge cycle≥1600 times 3. Extremely low self-discharge. In two years at the temperature of 20, self-discharge is less than 40% of the rated capacity 4. The battery has good recovery capability of deep discharge. The battery can be charged to 95% rated capacity within 12 hours after deep discharge 5. Gas recombination efficiency reaches over 99% two months after float charging 6. Charging voltage: 2.35V/cellbalance charge, 20,2.23-2.25V/cellfloat charge 7. Maximum charging current 8. Environmental temperature: -20 +50the optimal working temperature 9. Relative humidity ≤90% 10. The battery shall be far from fire, organic solvent, and shall be protected from sunshine. The batteries in the same group shall be utilized at the same environmental temperature. Structural Characteristics:1. Plate: the positive plate, as a tubular plate, can effectively prevent active materials from falling. The framework of the plate is molded by casting with lead-calcium multi-element alloy while the active material adopts some additive prescription with exclusive excellent conductivity, which can decrease the batterys inner resistance, improve the active materials efficiency and enhance the batterys service life. The negative plate is a pasted plate with the grid in the shape of radial structure, which can be beneficial to improve the utility of active materials and large-current discharge. 2. Electrolyte: the batterys electrolyte is a kind of colloid and is made of imported fumed silica. It is diluted sol while infused at first and fill the whole pole space inside the battery, in order to make reaction of each part of the pole even. Its flooded-electrolyte design can avoid dry-out in the condition of high temperature and over charging, and its large heat capacity and good heat dispersion can prevent from thermal runaway, so it is more environmental-friendly. The gelled electrolyte inside finished batteries is not removable, so there is no liquid leakage or stratification. 3. Separator: special AGM separator or microporous PVC-SiO2 partition for gelled batteries with large porosity and low electric resistance. 4. Container lid: the container case and lid are made of high-strength ABS materials with hot-melt sealing to ensure no leakage. 5. Pole: embedded with assembled copper-core poles, double assembly of close welding + special adhesive seal, which can ensure reliability of pole sealing. 6. Safety valve: the valve originated from German technologies, with constant open valve pressure and high reliability can avoid expansion and rupture of battery shells as well as electrolyte dry-out.
