Wow, a lifetime of 137 years at one cycle per day. This could make off-grid systems mainstream.
Long-time offgridder here. Would love to have a reasonable alternative to lead-acid or lithium. Opted for lead-acid again on the last battery swap around 5 years ago. Squeezed about 12 years out of the last set -though they were pretty degraded by that time. This bank is depreciating faster, probably because of increased use.
Lead acid batteries seem to be less and less reliable lately. The warranties are shorter and shorter as well, which is the best supporting evidence I have beyond needing batteries more often for the 4-5 vehicles I maintain.
