Warranty for 10 kilowatt hour (kWh) ZBM2 and ZCell zinc-bromine flow batteries is now 10 years.

Previously, Redflow warranted the electrode stack in its batteries for 10 years or 36,500 kilowatt hour (kWh) output, whichever came first, and for three years for auxiliary components such as electrolyte tanks and pumps.

Redflow’s entire battery is now covered by the 10-year/36,500kWh warranty, which aligns it with emerging industry standard warranties for residential and commercial energy storage systems.
