An AED is only useful if it's ready the day you reach for it, so the two questions buyers ask most are about maintenance and consumables. Defibtech units run automated self-tests and show a clear status indicator, but the batteries and electrode pads are dated components that expire and must be tracked. Plan on replacing pads roughly every two years and batteries on the manufacturer's stated schedule, and keep a spare set on hand. Pediatric-capable pads or a pediatric mode matter for any location serving children under about 55 lbs.

Choosing between semi-automatic and fully automatic usually comes down to your responders: fully automatic models suit settings where a lay rescuer may freeze at the shock button, while semi-automatic gives the operator final control. Either way, pair the device with a wall cabinet, signage, and a fast-grab response kit so the AED is visible and complete.
