Factory Direct: DKGB2-1500-2V1500AH Sealed Gel Lead Acid Battery

1. Charging efficiency: The usage of imported low resistance raw materials and advanced process help make theinternal resistance smaller and the acceptance ability of small current charging stronger. 2. High and low temperature tolerance: Wide temperature range (lead-acid:-25-50 C ,and gel:-35-60 C), suitablefor indoor and outdoor use in varies environments. 3. Long cycle-life: The design life of lead acid and gel series reach to more than 15 and 18 years respectively, forthe arid is corrosion- resistant. and electrolvte is without risk of stratification by using multiple rare-earth alloy ofindependent intellectual property rights, nanoscale fumed silica imported from Germany as base materials, andelectrolyte of nanometer colloid all by independent research and development. 4. Environment-friendly: Cadmium (Cd), which is poisonous and not easy to recycle, does not exist. Acid leakageof gel electrolvte will not happen. The battery operates in safety and environmental protection. 5. Recovery performance: The adoption of special alloys and lead paste formulations make a low self-dischargerate, good deep discharge tolerance, and strong recover capability.

Storage and shipping

Daily maintenance contents of storage battery (1) Remove surface dust; (2) Check the connection for looseness, heating and corrosion; (3) Check the battery case for leakage and deformation; (4) Check whether acid mist escapes around the pole and safety valve; (5) Check whether the floating charge voltage of the storage battery is normal; (6) Check whether the temperature of the storage battery is normal; (7) Measure whether the floating charge voltage of single battery is within 2.25 ± 0.03V; (8) The battery pack is connected to a DC load of about 2000W. When the discharge current is about 10A, check whether the voltage of the single battery is normal; (9) For battery packs that have been put into operation for many years, if the internal resistance of individual individual batteries increases and the performance decreases, the solution is maintenance and activation, that is, cleaning the electrode plate, replacing the electrolyte and repeatedly charging and discharging with large current; It is not recommended to replace a few new batteries, or the internal resistance of the new and old batteries will be different, which will lead to poor performance of the whole battery group and greatly reduce the service life of the whole battery group.
