A note about Rechargeable Batteries: Rechargeable batteries are designed for a "high-use" environment, such as Emergency Medical and Rescue Services, and hospitals. They also require a battery charging unit, and multiple batteries (one in use, one charging per AED). If your facility is not likely to use your AED frequently, we recommend the long-life, maintenance-free, non-rechargeable lithium battery.
ZOLL brand AEDs operate on batteries only. Always have a fully charged spare available.
