Ready immediately no settling or thermal waiting required Twice as powerful as lithium-ion batteries Wide operating temperature range (-30☌ to +50☌) The Blue Pack and Blue Rack battery cabinet are designed specifically for mission-critical applications, with features including: Prussian blue contains no rare-earth minerals, acid, or heavy metals, and Prussian blue is non-toxic, simplifying end-of-life removal. Lithium mining, by contrast, has a long history of alleged human rights abuses. The Blue Pack battery's breakthrough Prussian blue sodium-ion chemistry is sustainably and ethically sourced.

They are the only UL-listed sodium-ion battery on the market and can be shipped fully charged by ground or air, unlike either lithium-ion or lead acid.

They suffer no damage or performance loss from short circuits or up to 35% overvoltage overcharge. They are nonflammable, even when penetrated by a nail or exposed to flame. Natron's sodium-ion batteries are the safest industrial battery technology available. Sodium-ion recharges in five to 15 minutes, compared to an hour for lithium-ion and eight to 16 hours for lead acid. Its sodium-ion technology can produce far greater maximum sustained power per energy (40W/Wh) compared to lithium-ion (10W) and lead acid (7W), and its cycle life is five times greater than lithium-ion and 50 times greater than lead acid. The Blue Rack can be configured to provide up to 500kW of backup power.
