Times change and the UPS industry changes fast. Today the industry is demanding backup times of 2 to 5 minutes, which requires high energy density. Our UPS range was good, but we knew it could be better, that’s why we’ve relaunched our UPS range with enhanced electrochemistry.NorthStar high rate batteries use AGM thin plate pure lead technology, packed under high compression, which gives greater surface area to produce the required energy. This high energy density delivers more watts per cell, which can reduce your energy footprint by 10%.NorthStar high rate batteries now have a shelf life of up to 24 months without additional charging, which means less risk of having to scrap batteries. NorthStar high rate batteries also have higher temperature capabilities that allow data centres to increase operating temperatures and reduce electricity costs for cooling by more than 40%. Our batteries are designed for long life performance, which means fewer replacements and reduced operating costs of more than 20%.

Our solutions multiply battery lifetime and reduce energy consumption, delivering significant savings in operator OPEX
and CAPEX due to fewer battery replacements and maintenance visits. Other benefits include:
– Reduced environmental impact.
– High safety standards.
– Low maintenance design.
– Premium Construction materials.
– Integrated BMS platform standard.
– Integrated breakers and fuses.
– Integrated data comm available.
