The only descriptive DIFFERENCES on Northstar's website are:
NSB Blue+ Battery® - Fast recharge and high cycling
In many regions of the world the on-grid power supply is unreliable, suffering frequent power outages every day. This means frequent recharging, severely shortening battery life. To minimize the impact of outages or use of diesel
generators it is crucial to recharge batteries as quickly as possible - you never know when the next outage will be. At the same time, the cyclability of the battery needs to be exceptional, as the number of charging
cycles will be greatly increased when the grid goes down.
The NSB Blue Star Technology® offers recharge five times faster and can handle more than three times as many cycles than standard AGM's, thanks to its PSOC compatibility. This not only ensures a more reliable power supply, but also reduces the cost of operation.
NSB Red Battery® - Pure lead for long life
The NSB Red Battery
® provides exceptional performance and long float life, even at elevated temperatures. This means huge potential cost savings, due to reduced battery replacement and maintenance
“Our ambition has always been to develop the best performing product for every possible requirement,” says Jerry Hoffman, President of NorthStar Battery. “With this new pure lead design, we expect the Red Battery to be the best performing product for regions with a stable or semi-stable power grid. It’s the perfect addition to our product line, because now it doesn’t matter if you are setting up telecom equipment
in downtown New York
or in the middle of the Kalahari Desert, there’s a NorthStar battery to suit your needs.”
