DKGB-12120-12V120AH 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.

Gel battery, also known as gel lead-acid battery, is an improvement on the common lead-acid battery with liquid electrolyte. The gel electrolyte is used to replace the sulfuric acid electrolyte, which has improved the safety, storage capacity, discharge performance and service life of the battery. The gel battery adopts the gel manufacturing technology, and the electrolyte in the battery is fixed in the silicon gel. The fixation of electrolyte is due to the silica gel space network structure formed by the polymerization of gel gelal particles to effectively fix the sulfuric acid electrolyte. Its principle is similar to that of using gel to fix the sulfuric acid electrolyte.

The development of gel battery itself is based on the improvement of rich liquid battery. Since the sulfuric acid electrolyte is fixed with silicon gel, the gas transmission inside the gel battery is completed through the channel formed by the cracks caused by the cracking of the gel. The amount of electrolyte will not affect the gas transmission channel, so there is no strict limit on the amount of electrolyte. The liquid rich design is usually used to ensure that the battery has better performance.

gelal lead-acid battery adopts gel electrolyte, and there is no free liquid inside. Under the same volume, the electrolyte has large capacity, large heat capacity, and strong heat dissipation ability, which can prevent general batteries from being prone to thermal runaway; The electrolyte concentration is low, and the corrosion of the electrode plate is weak; The concentration is uniform and there is no electrolyte stratification. The discharge curve of gel battery is flat and straight, with high inflection point. Its energy and power are more than 20% larger than that of conventional lead-acid batteries, and its service life is generally about twice as long as that of conventional lead-acid batteries. Its high-temperature and low-temperature characteristics are much better. At the same time, it is a sealed structure, electrohydraulic gel, without leakage; No acid mist and pollution during charging and discharging.
