Pads
We stock and sell them. Contact us before buying something online. Many customers have been sold products that are incompatible with their specific AED!
Batteries
We recommend replacing batteries every 4 years. They "should" last 5 years, but since we run manual function tests bi-annually to comply with California law, there is no guarantee that they'll make it. It doesn't cost that much more to replace a little early to make sure the unit will work!
