Defibtech Lifeline & Lifeline AUTO Pads & Battery: Part Numbers
The Defibtech Lifeline is straightforward to maintain with one exception that catches people out: on some configurations there is a second, separate battery — a 9V lithium cell — in addition to the main pack.

Do not forget the 9V cell
The Lifeline uses a 9V lithium cell DAC-410 that powers the Active Status Indicator — the readiness light on the front. It is inexpensive and easy to overlook, and a dead one can make a perfectly healthy AED look unresponsive. The DCF-200 five-year pack ships with a 9V included; if you buy the main pack alone, check whether you also need the cell.
Reading the Active Status Indicator
Defibtech units report readiness through the Active Status Indicator rather than a screen. It is a quick monthly check — but remember it depends on that 9V cell, so an indicator showing nothing at all is as much a prompt to check the 9V as it is to suspect the main battery. More on diagnosis in why is my AED beeping.
Pediatric coverage
The Lifeline uses separate paediatric pads DDP-200P with their own expiration date. Diary it alongside the adult set — rarely-used paediatric pads are the most common expired item found at inspection.
Intervals
The DCF-200 pack is rated for five years. Pads are generally replaced around every two years or by their printed date, and always immediately after any deployment. Our Lifeline Maintenance Package bundles pads and battery in four tiers.
Frequently asked questions
What pads does the Defibtech Lifeline use?
Adult pads are part DDP-100 and paediatric pads are DDP-200P. Both fit the Lifeline and Lifeline AUTO. Note that the Lifeline VIEW uses different pads.
Does the Defibtech Lifeline have two batteries?
Effectively yes. There is the main battery pack (DCF-200 in the five-year configuration) and a separate 9V lithium cell (DAC-410) that powers the Active Status Indicator. The five-year pack includes a 9V cell.
Can I use Lifeline pads in a Lifeline VIEW?
No. The Lifeline VIEW, ECG and PRO use their own electrodes (DDP-2001 adult, DDP-2002 paediatric) and are not interchangeable with standard Lifeline pads.
