LUCAS 3.1 Power Supply & Battery Charger
The LUCAS 3 Auxiliary Power Supply connects to the DC input on the side of the LUCAS device and does two things at once: it powers the device from a mains outlet, removing the 45-minute battery limit entirely, and it recharges the installed battery in under two hours, ready for the next deployment.
Without this accessory, the LUCAS 3 battery provides 45 minutes of continuous compressions. For most emergency responses, that is sufficient. But for prolonged in-hospital resuscitation, extended pre-hospital scenes, offshore or remote locations with generator access, and high-frequency training environments, the power supply is essential equipment.
The power supply connects in all operating modes, and the device can continue delivering compressions while the battery charges. The LUCAS battery must always remain installed in the device, even when connected to mains power.
Supplied by Defib Store, authorised Stryker distributor. Compatible with LUCAS 3.0 and LUCAS 3.1. Using an unapproved power supply with the LUCAS device could cause damage and void the manufacturer's warranty.

LUCAS 3.1 Chest Compression Battery : The replacement battery has a 45-minute runtime. You can keep a spare charged for extended deployments or when the power supply is not available.
What Does the LUCAS 3 Power Supply Do?
The LUCAS 3 Auxiliary Power Supply has two functions. First, it powers the device directly from a mains outlet, removing the 45-minute battery limit and allowing the LUCAS to run for as long as resuscitation continues. Second, it simultaneously recharges the installed battery so the device is fully charged and ready the moment the mains connection is removed.
This dual function makes the power supply particularly valuable in three settings: in-hospital cardiac arrest (where a mains outlet is always within reach), prolonged pre-hospital scenes (where ambulance shore power or a nearby building supply can be used), and training facilities (where teams need to run the device repeatedly without waiting for the battery to recover between sessions).
The device connects through the DC input port on the side of the LUCAS unit and can also charge through the carrying case charger port without removing the device, useful between deployments when the device is packed and ready to go.
How Long Does the LUCAS 3 Battery Last?
The LUCAS 3 battery provides 45 minutes of continuous compressions (typical, nominal patient) when fully charged. A low-battery alert activates at approximately 30% capacity remaining, roughly 10 minutes of operating time. giving the team time to connect the power supply or swap the battery before it is depleted.
If mains power is not available, a LUCAS 3.1 replacement battery can be swapped in immediately to continue operation without interruption. Many teams carry a charged spare alongside the power supply for exactly this scenario.
With the Auxiliary Power Supply connected, there is no battery limit. The device can run indefinitely on mains power.
How to Charge the LUCAS 3 Battery
The LUCAS battery charges in under 2 hours when connected to the device via this power supply:
- Insert the battery into the slot in the hood of the LUCAS device
- Connect the power supply cord to the DC input on the side of the device
- Connect the mains cable to a wall outlet (100–240V, 50/60Hz)
- The battery indicator LEDs will show a running light while charging and a constant light when fully charged
- Charge time: under 2 hours at room temperature
The device can also be charged inside the carrying case, connected through the charger port access without removing the device.
Low battery alert: When the yellow Battery LED shows an intermittent light, connect the power supply or replace the battery immediately. Approximately 10 minutes of operating capacity remains at this point.
LUCAS 3 Charging Options - Which Is Best?
The LUCAS 3 battery can be charged three ways. Understanding the difference helps you choose the right option for your setting.
| Charging Method | Charge Time | Battery removed from device? | Is the device operational during charging? |
| Mains Power Supply Cable (this product) | Under 2 hours | No | Yes |
| Desktop battery charger | Under 4 hours | Yes, must be removed | No, device is inoperable |
| Car power Cable (12-28V DC) | Varies | No | Yes |
Who Uses the LUCAS 3 Power Supply?
The LUCAS 3 Auxiliary Power Supply is standard equipment for UK ambulance services, NHS emergency departments, air ambulance teams, and specialist cardiac centres that deploy the LUCAS device for prolonged resuscitation. The LUCAS 3 is also widely used in football stadiums and major sports venues, where pitchside medical teams have mains access and may need to sustain resuscitation for extended periods before a patient can be transferred. Training centres and simulation facilities use it to run the device continuously between scenarios without waiting for the battery to recover.
As an authorised Stryker distributor, Defibstore supplies LUCAS 3 devices and accessories to emergency services, NHS trusts, and healthcare organisations across the UK. Every power supply is supplied as a Stryker-approved accessory, essential for compliance with LUCAS warranty terms.
