DKGB-1240-12V40AH SEALED MAINTANANCE FREE GEL BATTERY SOLAR BATTERY
Technical Features
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 ℃, and gel:-35-60 ℃), 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.

AGM battery uses pure sulfuric acid aqueous solution as electrolyte, and its density is 1.29-1.3lg/cm3. Most of them are in the glass fiber membrane, and a part of electrolyte is absorbed inside the electrode plate. In order to provide a channel for the oxygen released from the positive electrode to the negative electrode, it is necessary to keep 10% of the pores of the diaphragm from being occupied by the electrolyte, that is, the lean solution design. The electrode group is tightly assembled so that the electrode plate can fully contact the electrolyte. At the same time, in order to ensure that the battery has sufficient life, the electrode plate should be designed to be thicker, and the positive grid alloy should be Pb '- q2w Srr -- A1 quaternary alloy. AGM sealed lead acid batteries have less electrolyte, thicker plates, and lower utilization rate of active substances than open type batteries, so the discharge capacity of the batteries is about 10% lower than that of open type batteries. Compared with today's gel sealed battery, its discharge capacity is smaller.
Compared with batteries of the same specification, the price is higher, but it has the following advantages:
1. The cycle charging capacity is 3 times higher than that of lead calcium battery, with a longer service life.
2. It has higher capacitance stability in the whole service life cycle.
3. The low-temperature performance is more reliable.
4. Reduce accident risk and environmental pollution risk (due to 100% sealed acid)
5. The maintenance is very simple, reducing deep discharge.
