Long Design Life

The use of heavy-duty lead-calcium alloy grids with anticorrosive constrution enablesthe NPC Batteries to remain in float service for 10 years.

High Energy Density

NPC has been improved to bring about 15% higher energy density (wh/I , wh/kg) than comparable batteries at long duration discharge helping to design equipments to be smaller, lighter and more cost effective.

NPC is equipped with anti-explosion device which improves safety

Characteristic

Uses a unique corrosion-resistant grid alloy, long service life.
All with high purity raw materials, battery self-discharge is minimal.
Using tight assembly technology with excellent high efficiency discharge performance.
With special design,the battery will not reduce the amount of electricity fluid during use,even no necessary to add any water during using life time.
Using gas compounds technology, the battery has a high sealing reaction efficiency, no mist precipitation, safety and environmental protection, pollution-free.
