Don’t Risk Liability with Cheap Generics.
This is not a “knockoff” battery.
The 9146-ABE is a premium, FDA-Cleared power unit that bridges the gap between expensive OEM batteries and risky, low-quality generics.
Most “compatible” batteries sold for $175 use cheap, unbranded Chinese cells inside a copycat plastic shell. We do it differently. We take the Original OEM Cardiac Science Plastic Core and professionally re-power it with brand-new, medical-grade Panasonic® or Sanyo® Lithium Cells—the exact same cells used by the original manufacturer.
✅ The “Premium Recelled” Difference
- Same Cells: We use the exact same Japanese Lithium cells as the $499 OEM battery.
- Same Fit: We use the original plastic casing, ensuring a perfect, weather-tight seal.
- Better Price: You save over $200 without sacrificing safety.

Comparison: Why Pay More for the 9146-ABE?
