Why we chose a 5-year full-replacement warranty over a 10-year repair plan

Look at most residential storage warranties and you'll see two patterns: long stated periods (10, 12, 15 years) and intricate small print — capacity guarantees that depreciate, regional clauses, exclusions for cycle counts, language about "repair at our discretion."

We considered going that route. We didn't.

Instead, NEXON ships with a 5-Year Full Replacement Warranty. Shorter window. Cleaner promise. No depreciation schedule, no capacity-percent maze, no ambiguous repair-or-replace clause. If something fails inside the 5-year period, we ship a new unit. Full stop.

Two reasons drove this. First, engineering: 5 years is the window in which the vast majority of latent manufacturing or component defects will appear. After that point, you're really insuring against the kind of wear that long warranties tend to caveat heavily anyway. Second, commercial: installers and homeowners value predictability more than they value duration. "5 years, no questions" lets a distributor quote a system without footnotes.

We'll keep watching the data. If our field reliability supports a longer full-replacement promise in the future, we'll publish it. Until then, the 5-year window is what we can stand behind without disclaimers — and that matters more than a longer number on a brochure.
