- Product size: 483*170*220, Gravity cast high purity lead-calcium-tin alloy plate grid.
- Minimum plate grid growth and strong corrosion resistance prolong service life.
- Nut type M6/M8 terminal ensures maximum conductivity, maximum torque retention and easy installation.
- Anti-leakage terminal sealing design to prevent acid leakage in a wide temperature range.
- Each cell is equipped with a one-way safety valve to allow excess gas discharge caused by overcharging.
- The gas filter prevents sparks or open flames from entering the inside of the battery, and the specially designed thick-walled plastic shell and center cap have extremely high mechanical strength.
- Self-discharge (20° C) is less than 2% per month, allowing 6 months of storage time.
