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 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.

What is a gel battery? Advantages and disadvantages of gel battery and lead-acid battery.
When buying high polymer gel battery and lead-acid battery, such a picture often appears. Whether to buy high polymer gel battery or lead-acid battery, it seems that the functions of the two products are very similar, so the business will hesitate to buy which one.
1. Environmental protection performance: the product uses high molecular polysilicon colloid electrolyte to replace sulfuric acid, which solves the problems of environmental pollution such as acid mist overflow and interface corrosion that have always existed in the production and use process. The electrolyte of discarded polysilicon battery can also be used as fertilizer, pollution-free, easy to handle, and the battery grid can also be recycled.
2. Charging acceptance capacity: the charging acceptance capacity is an important technical indicator to measure the battery. The high polymer gel battery can be charged with a current value of 0.3-0.4CA. The conventional charging time is 3-4 hours, which is only 1/4 of the charging time of the lead-acid battery. The current value of 0.8-1.5CA can also be used for fast charging. The fast charging time is less than 1 hour, which has broken through the 0.5 hour rate. When charging with large current, the high polymer gel battery has no obvious temperature rise, and will not affect the electrolyte characteristics and battery life. The fast charging characteristics of high polymer gel batteries have broad application prospects for industries requiring fast charging.
3. High current discharge characteristics: corresponding to the charging capacity, the discharge capacity of the battery is also an extremely important technical indicator. The shorter the battery with a rated capacity can be discharged, the stronger the discharge performance. The discharge standard of domestic communication battery is 10 hours, and that of power battery is 5 hours. Due to the extremely small internal resistance of electrolyte and good high current discharge characteristics, high polymer gel batteries can be discharged with 0.6-0.8CA current value generally. The short-term discharge capacity of power battery shall be up to 15-30CA. Tested by the National Battery Quality Inspection Center, the 2-hour discharge capacity of high polymer gel battery has reached the international advanced level.

Low temperature lithium iron phosphate battery 3.2V 20A
Low temperature lithium iron phosphate battery 3.2V 20A
-20 ℃ charging, - 40 ℃ 3C discharge capacity ≥ 70%
Charging temperature: - 20~45 ℃
-Discharge temperature: - 40~+55 ℃
-Maximum discharge rate supported at 40 ℃: 3C
-40 ℃ 3C discharge capacity retention rate ≥ 70%
4. Self discharge characteristics: small self discharge, good maintenance free, convenient for long-term storage. Due to the self discharge factor, ordinary lead-acid batteries should be discharged/charged once after being stored at 20 ℃ for 180 days, otherwise the battery life may be damaged. Since the internal resistance of high polymer gel battery is only one tenth of that of lead-acid battery, its self discharge electrode is small and has no memory effect. After being stored at room temperature for one year, its capacity can still maintain 90% of the nominal capacity, which ranks the international advanced level.
5. Full charge and full discharge capacity: high polymer gel battery has strong full charge and full discharge capacity. Repeated deep charging and discharging or even full charging and discharging have little impact on the battery. The lower limit protection of 10.5V (nominal voltage 12V) can be cancelled or reduced, which is very important for power lithium battery. The lead-acid battery is usually equipped with a 10.5V low-voltage protection device when in use, and cannot continue to discharge when it is lower than 10.5V. This is not only because of its poor low-voltage operating characteristics, but more importantly, the deep discharge will damage the electrode plate.
6. Strong self recovery ability: high polymer gel battery has strong self recovery ability, large rebound capacity, short recovery time, and can be reused several minutes after discharge, which is particularly beneficial to emergency use.
7. Low temperature characteristics: high polymer gel battery can be used normally in the environment of - 50 ℃ -+50 ℃, while the capacity of lead-acid battery drops sharply when it is used in the environment below - 18 ℃.
8. Long service life: the service life of communication power supply is more than 10 years. When it is used as power supply, the deep cycle charging and discharging times exceed 500 times (the national standard is 350 times).
