Defibrillator Batteries
Defibrillator batteries are a critical part of ensuring that your Automated External Defibrillator (AED) is always ready to respond in a sudden cardiac emergency. These specialised batteries power your device in standby mode and during use, and must be replaced at regular intervals to maintain full operational readiness. Whether you’re buying defibrillator batteries for workplace, community or home use, selecting the correct battery replacement for your AED model is essential for reliable performance when it matters most.

Why Defibrillator Battery Replacement Matters
Every AED battery has a defined standby life, typically ranging from around four to five years once installed, depending on the manufacturer and model. If a battery is allowed to expire or depleted, your defibrillator may not be able to deliver a life-saving shock when needed — so timely defibrillator battery replacement is a crucial part of AED maintenance.
In many devices, the AED monitors battery status and alerts you when the battery needs attention, but it’s good practice to track replacement dates and keep spare batteries on hand.
Choose the Right Battery for Your AED
Defibrillator batteries are not universal — each AED model requires a specific battery type. Our range includes manufacturer-approved battery replacements for popular AED brands such as Philips HeartStart, Zoll AED, Defibtech, Schiller and Mediana, with products offering multi-year standby life and capacities rated for hundreds of shocks.
Whether you need a standard lithium pack for your Philips HeartStart HS1, a high-capacity battery for a Defibtech model, or a long-life pack for Zoll AEDs, you’ll find the correct replacement right here. Batteries are non-rechargeable lithium units designed for long shelf life and dependable performance.
