Philips HeartStart OnSite/FRx Li-ion Battery
The low-maintenance Philips HeartStart OnSite/FRx battery offers a 5-year shelf life when stored outside the AED and a 4-year guarantee in standby mode when installed in the AED. Designed specifically for the Philips HeartStart OnSite and Philips HeartStart FRx AEDs, it ensures dependable readiness when needed most. Philips Healthcare recommends always keeping a fully charged spare battery stored with the AED for uninterrupted emergency preparedness.
