AED Models: Pads, Batteries and Maintenance by Model

AED pad and battery shelf life by model

Pads last about 2 to 5 years and batteries several years, depending on the model. This table lists each AED model in AED Log’s catalog with its adult pads, its child option and its battery, from the manufacturer’s own documents.

Shelf lives are the manufacturer’s figures; the date printed on your own pads and battery is the one to follow. Pads and batteries are model-specific, so check the part number before you order. Each model’s page has its part numbers, self-test schedule, status indicator, a maintenance checklist and any FDA recalls.

AED models by brand

AED Log’s catalog covers 8 AED brands and 27 models. Where two models share the same pads and battery, such as the Defibtech Lifeline and Lifeline AUTO, they share a page.

Brand names have moved around. Philips sold its AED business in January 2026, and it now operates as Heartstream. LIFEPAK AEDs were made by Physio-Control, which is now part of Stryker, and Stryker also owns HeartSine. Cardiac Science’s Powerheart AEDs now belong to ZOLL. Each page names the company whose documents we used.

Discontinued AED models

Some AEDs still in service are no longer sold, and a few no longer have pads or batteries made for them. If you own one of these, check that parts are still available, and plan a replacement before they run out.

• Philips HeartStart FR3: Still FDA-approved (since May 2020), but Heartstream's US site doesn't list or support it, and no end-of-sale date has been published.
• Philips HeartStart FR2 and FR2+: Philips stopped taking FR2+ orders on May 18, 2009, announced the end of support on December 31, 2018, and took its last US pad and battery orders on December 31, 2020.
• Philips HeartStart ForeRunner: No longer sold and not on the FDA's list of approved AEDs; neither Philips nor Heartstream has published an end-of-sale or end-of-support date.
• LIFEPAK CR Plus and EXPRESS: Stryker ended US sales of both models on November 27, 2019 and promised service, CHARGE-PAKs and electrodes for each unit's warranty life (8 years for the CR Plus, 5 for the EXPRESS).
• LIFEPAK 500: Parts and repair support ended January 31, 2018, Stryker discontinued its batteries on February 3, 2020, and pads stopped being marketed for it after February 3, 2022.
• Cardiac Science Powerheart G3 Plus: No longer on ZOLL's US AED list, though ZOLL has published no end-of-sale or end-of-support date for models 9390A and 9390E and still posts their quick reference guide.
• Cardiac Science Powerheart G3 Pro: No longer on ZOLL's US AED list; units numbered 9300P-2xx, sold before 2007, lost factory repairs, batteries and pads on January 1, 2016, and ZOLL has published no end date for later units.
• Welch Allyn AED 10: First cleared by the FDA in 2002 as the MRL JumpStart; we found no current Welch Allyn manual, support page or end-of-support notice, and its FDA recalls all closed by 2012.
• Welch Allyn AED 20: First cleared by the FDA in 2000 for MRL, which sold it as the LifeQuest AEDefibrillator; we found no current Welch Allyn manual, support page or end-of-support notice, and its last FDA recall closed in 2011.

The FDA has required premarket approval for every AED and its necessary accessories since 2015. Makers of older, previously cleared pads and batteries had until February 3, 2022 to apply, and the FDA warned that unapproved accessories may stop being available for older AEDs after that. It tells owners of AEDs that aren’t FDA approved to keep them in service until they can replace them with one that is.

How AED Log tracks every AED model

AED Log tracks any AED: pick the brand and model from the built-in catalog, or type it in if it isn’t listed, then record its pads and battery with their dates and get a warning before either expires.

Each AED gets its own record with its serial number, location, responsible person and every pad set and battery, each with its own lot number and expiration date. The monthly inspection asks about the status indicator, the pads and the battery, and failed checks open a corrective action. When the FDA publishes a recall that matches one of your AEDs, AED Log puts a notice on that unit after a person has reviewed the match.
