What are the advantages and disadvantages of colloidal German solar cells and common lead acid batteries?

When Germany sunshine colloid battery and lead acid battery buy often appear in this picture, it is buying the German battery lead-acid battery or sun colloid, looks like these two products are similar, so businesses will be shilly-shally situation at the time of the purchase, in the end to buy that kind.
1, environmental performance: high molecular polymerized silicon colloid electrolyte to replace sulfuric acid using this product, to solve the problem existed in the process of production and use of acid mist overflow and interface corrosion of environmental pollution, and waste battery electrolyte can be polymerized silicon fertilizer, no pollution, easy processing, battery grid can be recovered then.
2, charging capacity: charging capacity is an important measure of the battery technical indicators. Colloid Germany solar battery can use 0.3-0.4CA current value charge, the conventional charging time is 3-4 hours, only the lead-acid battery charging time 1/4. Can also use 0.8-1.5CA current value fast charging, fast charging time <1 hours, has exceeded 0.5 hours rate. When heavy current is charged, the German solar cell has no visible temperature rise, nor does it affect electrolyte properties and battery life. The rapid charging characteristics of colloidal German solar cells have broad application prospects for solving the fast charging industry.
3 、 large current discharge characteristics: corresponding to the charging capacity, the discharge capacity of the battery is also an extremely important technical indicators. A rated capacity of the battery can use the shorter time to complete the power, indicating the more powerful discharge performance. The discharge standard of domestic communication battery is 10 hours, and the power storage battery is 5 hours. Because of the small electrolyte resistance and high discharge characteristics, the German solar cell can be discharged with 0.6-0.8CA current value. Power battery, short time discharge capacity requirements as high as 15-30CA. By the national quality inspection center for testing battery, high energy discharge rate 2 hours battery capacity has reached the international advanced level.
4 、 discharge characteristics: small discharge, good maintenance free, easy to save for a long time. Ordinary lead-acid batteries due to self discharge factors, usually stored at 20 degrees in the environment, 180 days after the need for a charge / maintenance, otherwise it may damage the battery life. High energy colloid storage battery due to its internal resistance is equivalent to only 1/10 of the lead-acid battery, so its self discharge, no memory effect, stored at room temperature, the capacity can still maintain a nominal capacity of 90%, the indicators have reached the international advanced level.
5, full charge full discharge capacity: colloid Germany sunshine battery, full charge, full discharge capacity. Repeated repeated charge and discharge, or even full charge full discharge, have little effect on the battery. It can cancel or reduce the 10.5V (nominal voltage 12V) lower limit protection, which is very important for the power battery. The lead-acid battery is usually equipped with 10.5V low voltage protection device, which can not be discharged when it is less than 10.5V. This is not only because of its low voltage operating characteristics, but more importantly, deep discharge will cause damage to the plate.
6, self recovery ability: colloid Germany sunlight battery has stronger self recovery ability, rebound capacity, recovery time is short, in the end after a few minutes of electricity can be used again, which is particularly favorable for emergency use.
7 、 low temperature characteristics: the colloid battery can be used normally at -50, -+50 degrees Celsius, while the lead-acid battery will drop when it is lower than -18 degrees.

8, long service life: used as communication power supply, the service life of more than 10 years, as power supply, deep cycle charging and discharging more than 500 times (national standard is 350 times).
.
So if the next time you buy a battery hesitant, you will be in accordance with the above comparison, and soon you can choose their own products. It really saves time, effort and worry.
