Structure and Characteristic of 4V4ah lead acid battery:
1. Lead-Calcium six alloy sheet grating and coated mounding plate electrode: high capacity and long service life.
2. Lead-Tin multiple alloy bus bars: Small internal Resistance, corrosion resistance and can stand long term floating charging.
3. Sealed Construction and safe explosion-proof:Advanced AGM septum, Absorbs optimum electrolytic without leaving dissociated liquid, full air cathode absorption and can be placed in any position.
4. ABS Engineering plastics shell: anti-aging
5. Silicon Fluorine rubber sealed safety cap: Safe and flameproof without leakage of corrosive gas and liquid.
6. AR electrolyte analysis: Low self-discharging.
7. Maintenance free: No need to add distilled water and electrolyte
LONGWAY standard series valve regulated lead acid batteries are designed with AGM(Absorbent Glass Mat) technology and for general application purpose, such as UPS, telecom, and electrical utilities with 5 years design life, the batteries comply to the most popular international standards, such as IEC60896-21/22, BS6290-4, Eurobat Guide. The battery container and cover are available both in VO class flame retardant ABS or HBO ABS plastics.
