Pads and batteries

Do pads and batteries have a shelf life?

Yes. Both pads and batteries expire and will need replacing even if the defibrillator hasn’t been used.

The typical shelf life of pads and batteries is 2 to 5 years, depending on the defibrillator model – please check your user manual, consult the product detail page on our website or check the expiry date on your pad or battery.

Pad and battery expiry dates are typically displayed next to an hourglass or egg timer symbol.
