Product Description

12V 33Ah lead-acid battery for UPS system and solar system

•  Sealing

  It adopts battery slot cover and pole double seal design to prevent acid leakage. Reliable safety

  valve prevents air and dust from entering the battery interior.

•  Maintenance free

  Strong regenerative capacity and high sealing reaction efficiency, so no need for water or

  acid maintenance during the entire battery use.

•  Safety and reliable

  Acid-free overflow,reliable safety valve closure, and explosion-proof equipment make the

  battery safer and more reliable.

•  long service life

  Corrosion-resistant lead calcium lead alloy grid, ABS corrosion resistant material and high

  sealing reaction efficiency ensure long battery life.
