What this class is and what to look at
Configurations rated for eight hours or more of discharge: low C-rate variants of standard containers or dedicated long-duration products. Relevant for capacity markets, evening peaks and off-grid data-center loads.
Because duration is set by the power-to-energy ratio, check that the 8 h figure is a published variant, not a calculation. Compare RTE at low C-rate, calendar life and whether the warranty is written in cycles or years.
