Defibtech Lifeline AUTO AED - 7 Year High Capacity Battery
The Defibtech Lifeline AUTO is a fully automatic AED designed to be used by anyone, no training required. Turn it on, follow the voice prompts, and the device does the rest, including delivering the shock automatically if one is needed. This version comes with Defibtech’s 7-year high capacity battery, the longest-life AED battery available from any manufacturer, giving you up to 300 defibrillation shocks and seven years of standby life before a replacement is needed.
If you are looking for a device that is straightforward to deploy, easy to maintain, and built to last, this is it.
Proven to Be the Easiest AED to Use
In an independent study by the University of Illinois, the Defibtech Lifeline was tested against five other market-leading AEDs. Participants delivered a defibrillation shock faster and more successfully with the Lifeline than with any other device tested. That is clinical evidence, not a manufacturer claim.
The reason is straightforward: there are no lids to open, no separate carry case to unzip, and no moving parts. A single oversized green button turns the unit on. A calm voice then guides the rescuer through each step. When a shock is required, the Lifeline AUTO delivers it automatically, no button press, no hesitation required.
Why Choose the 7-Year High Capacity Battery?
The 7-year high capacity battery is what makes this version of the Lifeline AUTO stand apart. No other AED manufacturer offers a battery with this standby life. In practical terms, that means:
- Seven years of standby life before a battery replacement is due.
- 300 defibrillation shocks available - more than double the capacity of the standard 5 year battery.
- 16 hours of continuous operation in the event of extended use.
- Lower long-term cost of ownership through fewer battery replacement cycles over the device lifetime.
For high-footfall locations, large workplaces, or any setting where the AED may be deployed for many years without frequent maintenance attention, the 7-year battery is the more practical choice. It also removes the decision fatigue of replacing sooner than necessary.
Also available: the Defibtech Lifeline AUTO with standard 5-year battery for locations where a lower upfront cost is the priority.

Maintenance, Self-Testing and Support
The Lifeline AUTO carries out automatic self-tests daily, weekly and monthly. A green status flash confirms the unit is rescue-ready. A red flash means an error has been detected and needs attention. The 7-year battery significantly reduces the maintenance cycle compared to shorter-life alternatives.
Two things to plan for:
• Electrode pads have approximately a 2-year shelf life and should be replaced at expiry or after any real deployment.
• 9V status indicator battery powers the self-testing system independently from the main rescue battery and needs annual replacement. This does not affect rescue performance, but skipping it will eventually trigger a status alert.
Defib Store offers AED servicing and maintenance contracts to manage replacements and monitoring on your behalf. We also provide CPR and defibrillator training for your team, and AED rental options for organisations that cannot fund an outright purchase.
Frequently Asked Questions
What makes the 7-year battery different from the standard 5-year battery?
The 7-year high capacity battery offers nearly double the shock capacity (300 shocks vs 125) and twice the continuous operating time (16 hours vs 8), alongside two additional years of standby life. It is the longest-life AED battery available from any manufacturer. For organisations that want to reduce maintenance intervals and total cost of ownership over the device’s lifetime, the 7-year version is the more cost-effective choice long term.
What is the difference between the Lifeline AED and the Lifeline AUTO?
The Defibtech Lifeline AED is semi-automatic: it analyses the heart rhythm and charges the pads, but the rescuer must press a button to deliver the shock. The Lifeline AUTO is fully automatic: it completes that final step on its own, delivering the shock without any button press. For settings where rescuers may have no training or may freeze under pressure, the AUTO removes that barrier entirely.
Do I need training to use the Defibtech Lifeline AUTO?
No. The Lifeline AUTO is designed so that anyone can use it effectively, regardless of medical training. Voice prompts guide the rescuer through every step, and the automatic shock means there is no decision to make. That said, pairing your AED with CPR training significantly improves cardiac arrest outcomes. Defib Store offers training to complement any purchase.
Can the Defibtech Lifeline AUTO be used on children?
Yes. An adapted paediatric CPR protocol is included. For paediatric defibrillation, separate Defibtech Lifeline paediatric electrode pads are recommended. Contact us for guidance on the correct accessories for this unit.
