LIFEPAK 1000 at a glance
The LIFEPAK 1000 is a semi-automatic AED from Stryker built with trained responders in mind: the ECG display version can show the heart rhythm and switch to manual control. It's still sold, and the FDA approved it (PMA P160026) on July 2, 2018.
| Detail | LIFEPAK 1000 |

| Ready indicator | OK symbol on the readiness display |
| CPR help | cprMAX settings and a CPR countdown timer; no CPR sensor |
| Storage range | 59 to 95°F (15 to 35°C) |
| FDA approval | July 2, 2018 (P160026) |
The LIFEPAK 1000 has 3 modes. In AED mode it analyzes the heart rhythm and the rescuer presses the shock button when told. Manual mode, meant for people trained to read ECGs, and ECG mode, which monitors through a 3-wire cable, both need the ECG display version. By default the first 3 shocks are 200, 300 and 360 joules, and every later shock stays at 360; an owner can set levels from 150 to 360 joules.
It weighs 7.1 lb (3.2 kg) with battery and pads fitted and is rated IP55. There's no CPR sensor, but its cprMAX settings can build extra CPR time into the protocol, such as CPR while the AED charges, and the screen counts down each CPR period. Event data moves to a PC by infrared, using CODE-STAT or DT Express software. The newest operating instructions we found on Stryker's site date from October 2008, so some details may differ on later software.
LIFEPAK 1000 with graphical display (99425-000023) and LIFEPAK 1000 with ECG display (99425-000025): how they differ
- LIFEPAK 1000 with graphical display (99425-000023): Works in AED mode with on-screen graphics and voice prompts, but can't show the ECG or use Manual or ECG mode.
- LIFEPAK 1000 with ECG display (99425-000025): Shows the ECG in AED mode and adds Manual mode, for people trained to read ECGs, and ECG monitoring through a 3-wire cable; it comes with a carry case.
Other Stryker LIFEPAK (formerly Physio-Control) models we cover: LIFEPAK CR2, LIFEPAK CR Plus and EXPRESS and LIFEPAK 500.
LIFEPAK 1000 pads
The LIFEPAK 1000's adult pads are EDGE System electrodes, packed in a REDI-PAK preconnect package and fitted with a QUIK-COMBO connector (catalog number 11996-000017). Stryker doesn't publish their full shelf life and only promises at least 18 months left when they ship, so track the Use By date on the packet.
Stryker's documents use 2 names for the adult pads. The 2008 manual calls them QUIK-COMBO electrodes with REDI-PAK preconnect system, and Stryker's store now sells them as EDGE System electrodes with QUIK-COMBO connector. The catalog number, 11996-000017, is the same. The packet carries a Use By date, written as year-month-day or year-month, and Stryker includes it in routine inspections.
Stryker sets 2 more limits: pads that have spent more than 24 hours outside their foil package shouldn't be used, and pads should be replaced after 50 shocks, because dried-out or damaged pads can arc and burn the skin. Spells as cold as -22°F (-30°C) or as hot as 140°F (60°C) are allowed for up to a week; any longer shortens pad life.
Using the LIFEPAK 1000 on children
Yes. For a child younger than 8 or lighter than 55 pounds (25 kg), plug Infant/Child Reduced Energy Defibrillation Electrodes (11101-000016) straight into the AED; Stryker says they cut the shock energy to a quarter.
Stryker sells the Infant/Child Reduced Energy Defibrillation Electrodes as a starter kit (11101-000017) and as a replacement set (11101-000016), each shipped with at least 18 months of shelf life left. They connect directly to the AED, not through a QUIK-COMBO cable, and Stryker's data sheet says they reduce the selected energy by a factor of 4.
Don't use Pediatric QUIK-COMBO electrodes on a child with this AED: Stryker warns they don't lower its energy. These child electrodes are also the subject of an open 2026 FDA recall over gel that can separate from the pad, listed in the recalls section below, so check any you keep with the AED.
For the general rules on child pads, ages and placement, see our guide to pediatric AED pads.
LIFEPAK 1000 battery
The LIFEPAK 1000 takes a non-rechargeable lithium manganese dioxide battery, catalog number 11141-000100. Installed in an AED that sits unused, it lasts 5 years in standby, and a new one can wait up to 5 years on the shelf before that.
The battery has its own fuel gauge. Press the gray button and 1 to 4 lights come on; a single light means it's time for a new battery. On the AED's readiness display, 1 bar in the battery symbol means low, and an empty symbol means very low, at which point the OK symbol goes out. When the low warning first appears, at least 30 shocks at 200 joules or 75 minutes of use remain. From new, expect about 440 shocks at 200 joules, or around 1,030 minutes with the AED switched on.
Its label carries a Use By date in YYYY-MM-DD form. Stored at 68 to 86°F (20 to 30°C), an uninstalled battery keeps 5 years and still delivers 48 months of standby after that. The 2008 manual lists it under an older catalog number, 21300-006054. Before throwing a used battery away, discharge it fully, using the plastic cap that comes with the new one, and follow local rules.
How other models compare is in our AED battery replacement guide.
LIFEPAK 1000 part numbers and shelf life
These are the parts a LIFEPAK 1000 owner replaces, with Stryker's catalog numbers. For both pads Stryker states only a minimum shelf life at shipment, not a full one.
| Part | Part number | Shelf life | Replace |
|---|---|---|---|
| EDGE System electrodes with QUIK-COMBO connector and REDI-PAK preconnect system Adult pads | 11996-000017 | Not stated by Stryker (at least 18 months left when shipped) | By the Use By date on the packet, after use, after 50 shocks, or after 24 hours out of the foil |
| Infant/Child Reduced Energy Defibrillation Electrodes Children under 8 or under 55 lb (starter kit 11101-000017) | 11101-000016 | Not stated by Stryker (at least 18 months left when shipped) | By the Use By date, or after any use |
| LIFEPAK 1000 lithium battery Battery (non-rechargeable lithium manganese dioxide) | 11141-000100 | 5 years in standby once installed; up to 5 years on the shelf before that | By the Use By date, when the fuel gauge shows 1 light, or when the AED shows a low battery |
The app catalog's generic "Battery" entry for the LIFEPAK 1000 is this lithium battery. Stryker's battery instructions also cover a second number, 11141-000156, without saying how it differs from 11141-000100.
Need replacements? Total AEDs, AED Log’s sister store, sells pads, batteries and the AED itself for the LIFEPAK 1000. Any authorized distributor works; the FDA advises buying AED accessories only from authorized sources.
LIFEPAK 1000 self-test and status indicator
The LIFEPAK 1000 tests itself every day and every month at 3:00 a.m., and again each time it's turned on. An OK symbol on the readiness display means it's ready; a wrench symbol or a low or empty battery symbol means it needs attention.
The 3:00 a.m. daily and monthly tests run only while the AED isn't in use. Each time it's switched on, it also spends about 5 seconds checking its internal electrical parts and circuits, and it saves the results in a test log. The small readiness display stays visible while the AED is off. If a self-test finds a fault that needs service, the OK symbol disappears and a wrench symbol takes its place.
If a fault turns up while the AED is on, it gives the prompt CALL SERVICE. Stryker says to keep using it in an emergency anyway and have it serviced afterward. The data sheet also lists an optional service alert, a sound the AED makes when it needs servicing.
If the indicator ever shows a problem, our guide to AED self-test failures and status lights covers what to do first.
LIFEPAK 1000 maintenance checklist
Stryker says to inspect the LIFEPAK 1000 on a regular schedule, and weekly if it's rarely used: the OK symbol, the battery level, the pad Use By date and the supplies. Inspect and clean it after every use, too.
- The readiness display shows the OK symbol, with no wrench and no low or empty battery symbol.
- The battery's fuel gauge shows more than 1 light, and the battery's Use By date hasn't passed.
- The adult pad packet is sealed and within its Use By date.
- Any Infant/Child Reduced Energy electrodes kept with the AED are sealed, in date and not from a recalled lot.
- Pads and the other supplies and accessories you need are with the AED.
- The AED is stored between 59 and 95°F (15 and 35°C).
After the LIFEPAK 1000 is used
- Inspect the AED for damage.
- Clean it.
- Check that pads and all the other supplies and accessories are back with the AED.

How AED Log tracks the LIFEPAK 1000
In AED Log you pick the LIFEPAK 1000 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.
LIFEPAK 1000 FAQ
How long do LIFEPAK 1000 pads last?
