X-Sense SC07 (10-year sealed battery) review 2026

UL 217 & UL 2034 certified smoke + CO combo, 10-year sealed battery, LCD display — reported as a top pick among combo alarms

PriceFrom $42.99 · checked Sep 21, 2026

Is the X-Sense SC07 Worth It?

Best overall smoke & CO alarm. Dual UL certification plus a sealed 10-year battery removes the two most common ways people let a smoke alarm go dead — a forgotten battery swap or an uncertified sensor. A strong, simple default for most rooms.

X-Sense SC07 Pros & Cons

Pros
  • Certified to both UL 217 (smoke) and UL 2034 (CO) — the two standards that matter for this device type
  • 10-year sealed battery — no annual battery swaps, no dead-battery chirps
  • LCD display shows live status; reported among top picks for combo alarms
Cons
  • Battery-only — no hardwire/AC backup option on this model
  • Not app-connected
  • Sealed battery means the whole unit is replaced at end of life, not just a battery
