Colloidal battery and lead-acid battery have the same performance. But the electrolyte in the battery is a semi solidified emulsion state and a liquid state. Liquid lead-acid batteries need to be maintained by adding distilled water irregularly during use, and colloidal batteries do not need to be maintained by adding distilled water.
Lead acid battery: the electrode is mainly made of lead and its oxide. The electrolyte is a battery of sulfuric acid solution. In the discharge state, the main component of the positive electrode is lead dioxide and the main component of the negative electrode is lead. Under the charging state, the main components of the positive and negative electrodes are lead sulfate.
Performance characteristics of lead-acid battery
Safety seal
During normal operation, the electrolyte will not leak from the terminal or housing of the battery.
No free acid
A special suction baffle keeps the acid inside. There is no free acid inside the battery, so the battery can be placed in any position.
Venting system
When the internal pressure of the battery exceeds the normal level, the VRLA battery will release excess gas and automatically reseal. Ensure that there is no excess gas in the battery.
Simple maintenance
Due to the unique gas composite system, the generated gas is converted into water. There is no need to add water during the use of the battery.
Long service life
Lead calcium alloy breast board with anti-corrosion structure is adopted, and the battery can be used for floating charge for 10-15 years.
Stable quality and high reliability
With advanced production technology and strict quality control system, the battery has stable quality and reliable performance. Voltage, capacity and sealing shall be 100% inspected on the line.

Colloidal battery is an improvement of ordinary lead-acid battery with liquid electrolyte. Colloidal electrolyte is used to replace sulfuric acid electrolyte. Compared with ordinary batteries, it has improved in safety, power storage, discharge performance and service life.
Working principle of colloidal battery
The performance of colloidal lead-acid battery is better than that of valve regulated lead-acid battery. Colloidal lead-acid battery has stable performance and high reliability. Long service life, strong adaptability to ambient temperature, long-time discharge capacity, cyclic discharge capacity, strong deep discharge and high current discharge capacity, and has the advantages of overcharge and over discharge self-protection.
Colloidal lead-acid batteries began to crack and shrink after being used for a period of time. Cracks are generated, and oxygen is directly sent to the negative plate through the cracks for oxygen circulation. The exhaust valve is no longer often opened, and the colloidal lead-acid battery is close to sealing, with little water loss. Therefore, for the electric bicycle battery, the main failure is the water loss mechanism, and the colloidal battery can achieve very good results. Colloidal electrolyte is made by adding gel into the electrolyte to solidify the sulfuric acid electrolyte into a colloidal substance. Generally, colloidal stabilizer and compatibilizer are added to colloidal electrolyte, and retarding colloidal solidification and retarding agent are added to some colloidal formulas to facilitate colloidal filling.
