Why can’t I find this FDA-Cleared 9146-ABE Recelled Battery on Amazon?

Amazon’s internal seller policies strictly prohibit listing remanufactured medical devices. Because we take the original OEM Cardiac Science core and re-power it with fresh Japanese cells, Amazon classifies it as remanufactured. Legitimate, FDA-cleared (K120350) recelled batteries like ours are sold through authorized medical distributors.

Are generic replacement G3 batteries on third-party marketplaces safe?

Most cheap compatible batteries found on open marketplaces are fully aftermarket copies. They use unbranded generic cells inside copycat plastic shells, lacking 510(k) FDA clearance and running a much higher risk of self-test failure or casing leakage.

What is the difference between the OEM battery and the 9146-ABE?

Both units use the exact same Japanese Panasonic or Sanyo lithium cells, the original Cardiac Science plastic housing for an airtight seal, and carry full FDA clearance. The 9146-ABE delivers the identical 4-year installed standby life and 300-shock capacity without the factory retail markup.

What is a “Premium Recelled” AED battery?

A premium recelled battery bridges the gap between expensive OEM parts and risky generics. The 9146-ABE is built by taking the genuine Cardiac Science casing and professionally repowering it with brand-new, medical-grade lithium cells—the exact cells used by the original manufacturer.

Which Cardiac Science AED models are compatible?

The 9146-ABE is compatible with Cardiac Science Powerheart G3 and G3 Plus AEDs (models 9300A, 9300E, 9390A, and 9390E). It does not fit the G3 Pro (which takes the 9145 series) or the G5 (which takes part XBTAED001A).

How long does the 9146-ABE replacement battery last?

The 9146-ABE features a full 4-year installed operational standby life (and a 5-year uninstalled shelf life), delivering up to 300 defibrillation shocks or 12 hours of continuous monitoring.
