Lifeline VIEW at a glance
The Lifeline VIEW is Defibtech's semi-automatic AED with a color video screen, and the Lifeline ECG is the same AED with a non-diagnostic ECG view added. Defibtech still sells both and issued a new user manual for them in July 2026.

Both models are semi-automatic. When the AED finds a shockable rhythm it charges, but nothing happens until the rescuer presses the flashing SHOCK button, and the shock is cancelled if nobody does within 30 seconds. The screen plays video instructions with matching text, and an information softkey plays extra help videos, for example on getting the patient ready and on CPR. CPR coaching is set to compressions only by default; rescue-breath prompts can be added with a softkey mid-rescue or turned on in the settings. Both give 150 joules with adult pads and 50 with child/infant pads.
On the ECG, a Mode Select softkey flips the screen between the video and the rhythm read through the pads, with heart rate, elapsed time and shock count. Defibtech calls that view non-diagnostic, and the heart rate never sets off an alarm. The manual describes no manual override: the AED still decides when to advise a shock. The FDA approved a newer Defibtech family in July 2026, the Lifeline VIEW 2, VIEW 2 AUTO and ECG 2, along with DDP-2004 Universal Pads.
Lifeline VIEW (DDU-2300) and Lifeline ECG (DDU-2450): how they differ
- Lifeline VIEW (DDU-2300): Semi-automatic, with a color screen that plays video instructions, text prompts and CPR coaching during a rescue.
- Lifeline ECG (DDU-2450): The VIEW plus a Mode Select softkey that switches the screen to a non-diagnostic view of the patient's rhythm, heart rate, elapsed time and shock count.

Lifeline VIEW pads
The VIEW and ECG take DDP-2001 adult pads, which Defibtech's July 2026 manual dates 2.5 years from manufacture. The date is printed on the pouch and shown on the AED's status screen, and the AED says "Pads expired" once it has passed.
The AED has a slot in its back that holds one sealed DDP-2001 package, and Defibtech recommends storing it with that set plugged in. Keep the pouch closed until a rescue, because the gel can dry out once it's opened, and throw the pads away after use. These pads don't fit the original Lifeline, which takes DDP-100.
The 2.5-year figure assumes storage at about 72°F (22°C). Defibtech warns that storing pads close to either end of the 32 to 122°F (0 to 50°C) range for longer than about a week can cut their life short. Its undated online catalog also calls each package good for 2 years rather than 2.5. Either way, the date that counts is the one on the pouch, which the status screen also shows.
Using the Lifeline VIEW on children
Yes: for a child younger than 8 or lighter than 55 lb (25 kg), Defibtech's choice is the DDP-2002 child/infant pads, and the AED announces Pediatric mode and drops the shock to 50 joules. With none at hand, Defibtech says to go ahead with the adult pads instead of waiting.
The DDP-2002 child/infant pads are meant for a child younger than 8 or lighter than 55 lb (25 kg). They have a blue connector and package, and once they're plugged in the AED says and shows "Pediatric mode" and lowers the shock from 150 to 50 joules. The slot on the back holds only the adult set, so Defibtech suggests keeping the child pads nearby, for example in a carrying case, but not connected.
If no child pads are available, Defibtech says to use the adult pads in the child position and go ahead with the rescue. The manual gives the DDP-2002 the same 2.5 years from manufacture as the adult pads, but the two sets can carry different dates, so check each pouch.
For the general rules on child pads, ages and placement, see our guide to pediatric AED pads.
Lifeline VIEW battery
The VIEW and ECG run on the DBP-2003, a lithium battery pack that can't be recharged and lasts about 4 years installed, with the automatic self-tests already allowed for. There is no separate 9V battery: the same pack powers the status light.
The DBP-2003 is a lithium manganese dioxide pack (12 V, 2800 mAh) rated at 125 shocks (or 8 hours running). It can't be recharged. Defibtech sells it as the 4-year replacement pack DCF-2003. Each pack has a printed expiration date, and the status screen shows its expiration month; don't install a pack after that date. For use on a commercial aircraft, Defibtech says to fit the DBP-2013 aviation pack (kit DCF-2013), which has the same 4-year standby life.
The July 2026 manual adds a caution: the printed date presumes only the built-in test schedule and ordinary use, and each manual self-test spends one shock's worth of charge, so frequent manual tests shorten the pack's life. During a rescue, a battery symbol on screen gives a rough idea of the remaining charge. The first "Battery low" prompt leaves at least 3 shocks; "Replace battery now" warns that a shock may no longer be possible.
How other models compare is in our AED battery replacement guide.
Lifeline VIEW part numbers and shelf life
These are the parts a Lifeline VIEW or ECG owner replaces, with Defibtech's part numbers and stated lives. Both models take the same pads and battery packs.
| Part | Part number | Shelf life | Replace |
|---|---|---|---|
| Adult Defibrillation Pads Adults, and children 8 and up or over 55 lb | DDP-2001 | 2.5 years from manufacture | By the date on the pouch or status screen, or after any use |
| Child/Infant Defibrillation Pads A child younger than 8 or lighter than 55 lb | DDP-2002 | 2.5 years from manufacture | By the date on the pouch or status screen, or after any use |
| Lithium battery pack Battery, 125 shocks (sold as DCF-2003) | DBP-2003 | 4 years in standby | By the date on its label, or when the AED asks |
| Aviation battery pack Battery for use on commercial aircraft (kit DCF-2013) | DBP-2013 | 4 years in standby | By the date on its label, or when the AED asks |
Defibtech's undated online catalog gives 2 years for both pad sets; the figures above are from the July 2026 user manual. You need the DBP-2013 only if the AED flies on commercial aircraft.
Need replacements? Total AEDs, AED Log’s sister store, sells pads, batteries and the AED itself for the Lifeline VIEW. Any authorized distributor works; the FDA advises buying AED accessories only from authorized sources.
Lifeline VIEW self-test and status indicator
The Lifeline VIEW checks itself whenever it's switched on and runs its own daily, weekly, monthly and quarterly tests. A single green flash from the status light means ready; red double flashes with double beeps, or no light at all, mean it needs service.
Along with the power-on check and the daily, weekly, monthly and quarterly tests, the AED tests a battery pack when it goes in, provided the pack has been out for at least 10 seconds. The tests look at the buttons and controls, battery condition, the charge and discharge circuits, and ECG signal measurement. For a manual test, start with the AED off, tap the center softkey to bring up the status screen, then choose the tool icon, AED maintenance and Perform AED test. A pass ends with "AED OK".
Opening that screen doesn't start a rescue, and it lists the AED's condition, the battery and pad expiry dates, the serial numbers and the software version. The status light uses one green flash for ready and two red flashes for trouble, which helps people with color blindness. On software 2.7 or later it can also radio its status to optional remote-monitoring equipment at every power-down, automatic tests included. That feature is off until enabled in Maintenance Mode; the FDA approved its labeling in June 2026.
If the indicator ever shows a problem, our guide to AED self-test failures and status lights covers what to do first.
Lifeline VIEW maintenance checklist
Defibtech's sample schedule has you check the status light daily, check the AED, its accessories and their dates regularly, and, if you use it, confirm readiness through remote monitoring. Its checklist also asks for a spare battery pack and spare pads.
- The status light gives a single green flash, with no red flashes or double beeps.
- The adult pads are plugged in, their pouch is sealed in the slot on the back, and its date hasn't passed.
- Any DDP-2002 child/infant pads are sealed, in date and kept near the AED.
- The battery pack is within its printed expiration date (the status screen shows it next to the pad date).
- If you use remote monitoring, it reports the AED as ready.
- The AED is clean and undamaged and kept within 32 to 122°F (0 to 50°C), where its light can be seen and its beeps heard.
- Spares are ready, per Defibtech's checklist: one battery pack and one set of pads.
After the Lifeline VIEW is used
- Clean the AED.
- Connect a new, in-date adult pads package.
- Run a manual self-test from Maintenance Mode.
- Switch the AED off and check for the single green flash.

Lifeline VIEW recalls
The FDA's recall database lists one recall of the Lifeline VIEW and ECG that reached US owners: a 2020 Class II correction for a component problem that could abort a shock or reset the AED, closed in 2021. Defibtech's 2020 safety alert page still offers a serial-number check; the 9-digit serial label sits under the pads in the rear pouch.
| Date | Product | Class | What it’s about and what to do | Status | FDA record |
|---|---|---|---|---|---|
| Apr 27, 2020 | Lifeline VIEW, PRO and ECG | II | A component issue can abort a shock or reset the AED. | Closed 2021 | Z-2392-2020, Z-2394-2020 |
Every AED recall, by manufacturer, is on our AED recall list.
How AED Log tracks the Lifeline VIEW
In AED Log you pick the Lifeline VIEW from the built-in catalog, record its pads and battery with their lot numbers and dates, and get a warning before either expires, plus a monthly inspection reminder.
Each pad set and battery is its own record with its own expiration date, so a pad set or battery never lapses unnoticed. Choose the part from the catalog and its shelf life fills in the expiration date for you; you can always type the date printed on the package instead. Alerts go out by email, Slack, Teams or Discord to the people responsible for that site, and the monthly inspection checklist asks about the status indicator, the pads and the battery. See pad and battery expiration tracking and AED management for more, or see every AED model.

Lifeline VIEW FAQ
How long do Lifeline VIEW pads last?
Defibtech's July 2026 manual dates DDP-2001 adult and DDP-2002 child/infant pads 2.5 years from manufacture; its online catalog says 2 years. Follow the date on the pouch or the AED's status screen, and replace the pads after any use.
How long does the Lifeline VIEW battery last?
The DBP-2003 battery pack lasts about 4 years installed, with the automatic self-tests already allowed for, and is rated at 125 shocks. Replace it by the date on its label or when the AED asks. Frequent manual self-tests shorten its life.
Can you use the Lifeline VIEW on a child?
Yes. For a child younger than 8 or lighter than 55 lb, plug in DDP-2002 child/infant pads; the AED announces Pediatric mode and gives 50 joules instead of 150. If none are available, Defibtech says to go ahead with the adult pads instead of waiting.
What is the difference between the Lifeline VIEW and Lifeline ECG?
Both are semi-automatic AEDs with a video screen, and they share pads and batteries. The Lifeline ECG (DDU-2450) adds a Mode Select softkey that shows the patient's rhythm, heart rate and shock count. That view is non-diagnostic and has no alarms.
Does the Lifeline VIEW have a 9V battery?
No. The status light draws its power from the main DBP-2003 battery pack, so if that pack is flat or missing, the light stays dark. That's one reason a status light showing no flash at all needs checking right away.
