Defibtech Lifeline SEMI Package - 7 Year Battery Life

Designed to military standards for shock and vibration resistance, this AED boasts high ratings for dust and water protection. It features a high-visibility yellow casing, a 7-year battery capable of 300 shocks, and a comprehensive 8-year warranty, including a soft carry case and rescue pack.

This semi-automatic unit is activated via a green power button. It uses calm voice prompts and visual progress lights to guide the rescuer through pad placement. The device automatically analyses the heart rhythm and, if required, instructs the user to press the shock button to deliver treatment.

What are the benefits of the 7-year AED battery?

This high-capacity Defibtech Lifeline SEMI battery offers an industry-leading 7-year standby life, delivering up to 300 shocks or 16 hours of continuous use. This long service interval is ideal for low-use environments, significantly reducing ongoing maintenance costs and the frequency of battery replacements compared to standard five-year models.

What does semi-automatic operation mean?

Semi-automatic means the Defibtech Lifeline SEMI analyses the patient’s heart rhythm and determines if a shock is needed. If it is, the rescuer is prompted to press the orange shock button. This ensures the user remains in control and everyone is clear of the patient before the electrical energy is discharged.

How durable is the Lifeline AED?

Built to withstand extreme conditions, the Lifeline is manufactured to military standards for shock and vibration. It is highly resistant to dust and water, making it suitable for use in harsh environments such as jet aircraft, helicopters, or industrial sites where standard electronic equipment might be easily damaged.

Can an untrained person use this semi-automatic AED?

Absolutely. The device features a simple two-button interface and a clear, calm voice that guides the rescuer one step at a time. Visual progress lights provide a frame of reference to support verbal instructions, helping even untrained bystanders manage high-stress emergencies without losing their place in the process.

Is it suitable for use on children?

The Lifeline AED can be used on paediatric patients under eight years or 25kg by installing dedicated paediatric pads, which are sold separately. These pads reduce the energy level of the shock to a safer amount, ensuring appropriate clinical treatment for younger victims while using the same reliable device.

Why is the unit bright yellow?

The bright yellow colour of the Lifeline series is specifically chosen for maximum visibility. This ensures that the AED can be located instantly during an emergency, even in cluttered or low-light environments like warehouses, schools, or community centres where rapid response is vital for a successful outcome.

What maintenance does the Defibtech Lifeline SEMI require?

Beyond replacing pads and the 7-year battery upon expiry, the device is very low-maintenance. It performs daily, weekly, and monthly self-tests to ensure the internal circuitry and battery are functional. A status indicator provides a quick visual confirmation that the unit is rescue-ready at all times.
