The Defibtech Lifeline AED is a battle-tested, public-access semi-automatic defibrillator delivering 150J biphasic truncated exponential therapy in under 4 seconds from shock advisory. Built to U.S. military specifications (IP54-rated, 1.2m drop-tested), it weighs just 4.2 lb and features two-button operation with voice guidance — making it one of the most reliable and operationally durable AEDs available for civilian and tactical environments.

Its engineering philosophy is disarmingly simple: two large, clearly labeled buttons (green power, red shock), extensive voice guidance, and a rugged housing tested to military standards. For coaches, office managers, teachers, and community leaders — people who may never have used an AED before — that simplicity is the most important feature. The clinical engine driving the Lifeline is its impedance-compensated biphasic truncated exponential waveform — the same waveform technology cited in AHA/ERC guidelines as meeting or exceeding clinical performance benchmarks. At 150J adult delivery, the Lifeline provides guideline-level therapy calibrated to the patient's individual transthoracic resistance. Charge time of 4 seconds or less minimizes the no-flow interval between CPR and shock delivery, a key determinant of neurological survival outcomes. Military-grade construction — tested per MIL-STD-810F for shock, vibration, dust, and water exposure — gives the Lifeline durability far beyond typical public-access electronics. At 4.2 lb with IP54 sealing and a 1.2m drop rating, it survives the real-world abuse of sports sidelines, industrial floors, and rapid deployment from wall cabinets. The 7-year battery standby life (standard DBP-1400) and daily/weekly/monthly/quarterly self-test cycle minimize ongoing maintenance requirements. Battery Options Standard 5-Year Battery (DBP-1400): 300 shocks / 16 hours continuous — 7-year standby life. SKU: MEDTAC1073 High-Capacity 7-Year Battery (DBP-2800): 125 shocks / 8 hours — extended standby to 5 years in device.
