Lifepak CR2 Semi-Automatic Defibrillator with USB

Key Features of the CR2 (USB version)

Guides any responder, step by step

Open the lid, follow the bold graphics and spoken prompts. ClearVoice technology adjusts volume to the environment, so instructions stay audible in a noisy school corridor or gym hall. We consistently hear from customers that the CR2 is one of the devices their staff feel most confident using.

CPR coaching with real-time correction

A built-in metronome sets the compression pace, and the device provides spoken feedback on technique and depth. It detects when CPR has stopped and prompts the responder to resume. For workplaces where most staff have limited first aid training, this makes a material difference.

Escalating energy up to 360J

The CR2 delivers shocks at 200J, 300J, then 360J automatically,  no decision required. Higher energy increases effectiveness for patients who are more difficult to defibrillate or show more impedance.

One set of pads for adults and children

The QUIK-STEP electrode pads work for both adult and paediatric patients. Press the Child Mode button to reduce energy (50J / 75J / 90J) and adjust prompts for children aged 1-8 or under 25 kg. No separate paediatric pads to buy, store, or fumble with mid-emergency. Particularly valued in schools and sports clubs.

Semi-automatic, the responder presses the shock button

The device analyses the rhythm and advises when a shock is needed, but the responder delivers it. Many organisations and training providers prefer this because it keeps the responder engaged and aligns with standard first aid protocols.

USB data transfer for post-event reporting

After use, connect the USB cable to a computer to download ECG recordings, shock times, and responder actions. Ambulance services routinely request this data, and it supports your internal incident records. No Wi-Fi infrastructure or subscription required.

Self-testing and readiness monitoring

Daily, weekly, and monthly automatic checks verify battery, pads, and internal components. A green LED flashes every six seconds to confirm the device is ready. If something needs attention, the indicator changes so you can act before an emergency. 

Built tough, built compact

IP55 rated against dust and water. 2 kg, 9.7 × 22.6 × 27.4 cm. The white casing with distinctive red heart logo is designed for high visibility.  It has been tested to survive sudden, harsh impacts. It combines a specific, high-intensity shock test (IEC) with a widely recognised military-grade durability standard (MIL-STD). This is a defibrillator machine built for real-world conditions, not a shelf.

Technical Specifications

Where the CR2 is Used

We supply the CR2 USB to organisations of every size, from single-site offices to some of the busiest locations in the country. The LIFEPAK CR2 is trusted in high-footfall environments, including major UK airports such as Heathrow, where devices are kept on standby as part of their emergency response provision.

We also work with the Oliver King Foundation, whose founder, Mark King OBE, has been one of the most influential advocates for public-access defibrillation in the UK. The Foundation’s campaigning led directly to the government’s rollout of over 20,000 defibrillators to state funded schools across England, a programme that has already saved lives. Their trust in the LIFEPAK CR2 reflects the same standard of readiness we help every customer achieve.

Schools, workplaces, sports clubs, councils, GP surgeries, care homes, leisure centres, the CR2 USB fits wherever an organisation takes its duty of care seriously and needs dependable equipment without the complexity of wireless connectivity

Readiness and Replacement

Pads and batteries each last up to four years. When the battery-replace indicator appears, at least six shocks and thirty minutes of operating time remain, giving you time to order a replacement without any gap in cover.

Our free reminder service contacts you before consumables expire. Replacement LIFEPAK CR2 pads and batteries are available from Defibstore, and we offer servicing and maintenance support for organisations that want hands-off compliance.

Not ready to purchase outright? We also offer rental defibrillator options for events, seasonal venues, or organisations that prefer to spread the cost

Replacing a LIFEPAK CR Plus?

The LIFEPAK CR Plus has been discontinued. The CR2 is its direct replacement from Stryker, with significant upgrades: faster shock delivery, ClearVoice adaptive audio, built-in CPR coaching, a dedicated child mode button (no separate paediatric pads needed), IP55 protection, and USB data transfer. If your organisation still has a CR Plus, this is the recommended upgrade path.

FAQs

Is Lifepak CR2 rechargeable?

No, the CR2 is not rechargeable. The device battery can be replaced with a new CR2 replacement battery that has a battery life of up to 4 years.

What is the difference between the LIFEPAK CR2 semi-automatic and fully automatic?

The semi-automatic analyses the heart rhythm and tells you when a shock is advised; you then press the shock button. The fully automatic delivers the shock without a button press. Many organisations and training providers prefer the semi-automatic because it keeps the responder actively engaged and matches standard AED training.

Is it suitable for outdoor use?

The CR2 is IP55 rated, meaning it’s protected against dust and low-pressure water jets. It’s suitable for outdoor placement in an appropriate weatherproof cabinet. 

Is a defibrillator required in schools?

The government rolled out over 20,000 defibrillators to state-funded schools in England, and Ofsted increasingly recognises health and safety preparedness as part of safeguarding. While not a legal requirement in all settings, having an AED on-site is widely considered best practice. The CR2’s child mode and CPR coaching make it particularly well suited to school environments.

How does the CR2 check itself?

Automatic self-tests run daily, weekly, and monthly, verifying battery, pads, and internal components. A green LED flashes every six seconds to confirm readiness. If a fault is detected, the indicator changes so it can be resolved before an emergency.
