DKGB-1250-12V50AH 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.

performance index of OPzV battery
Colloid battery belongs to a development category of lead-acid battery. The method is to add gelling agent in sulfuric acid to change the sulfuric acid electrolyte into colloidal state. The battery with colloidal electrolyte is usually called colloidal battery. The difference between colloidal battery and conventional lead-acid battery has been further developed from the initial understanding of electrolyte gelling to the research of electrochemical characteristics of electrolyte infrastructure, as well as the application and promotion in grid and active materials. Its most important characteristics are: using less industrial cost to produce better batteries, its discharge curve is straight, the inflection point is high, its energy and power are more than 20% larger than conventional lead-acid batteries, its life is generally about twice as long as conventional lead-acid batteries, and its high-temperature and low-temperature characteristics are much better.
It belongs to a development category of lead-acid batteries. The simplest way is to add gelling agent in sulfuric acid to change the sulfuric acid electrolyte into colloidal state. The battery with colloidal electrolyte is usually called colloidal battery.
From the initial understanding of electrolyte gelling, it has been further developed to the electrochemical characteristics of electrolyte infrastructure, as well as its application in grid and active materials. [1]
The most important characteristics of gel battery are as follows:
1. The interior of the gel battery is mainly a porous network structure of SiO2, with a large number of tiny gaps, which can enable the oxygen generated by the positive pole of the battery to migrate smoothly to the negative pole plate, facilitating the absorption and combination of the negative pole.
2. Colloid battery has a large amount of acid, so its capacity is basically the same as AGM battery.
3. Colloid batteries have large internal resistance and generally do not have good high current discharge characteristics.
4. The heat is easy to diffuse, not easy to rise, and the probability of thermal runaway is very small.
