The 9V status indicator battery is the most-forgotten battery in a Defibtech AED program. It powers the small green/red readiness light separately from the main battery, which means the device can look “ready” (green light) even when the main battery is dead. This creates a dangerous false sense of readiness. Manual battery verification is the only reliable check. The 9V is inexpensive but critical: replace at least annually, and never skip the monthly visual check that confirms both batteries.
