How long does a Philips HeartStart battery last?
Four years installed, per Philips, with a five-year shelf life before installation. The battery powers daily self-tests and about 200 shocks or four hours of operation. Write the install date on the label; the OnSite and FRx flash a low-battery warning near the end.
How much does a Philips AED battery cost?
$249 at AED Leader and Response Ready on 18 September 2026 for the M5070A. Over a four-year cycle that is about $62 a year, roughly the same as the pads ($99 every two years, $49.50 a year).
Does the M5070A fit both the OnSite and the FRx?
Yes. M5070A is the one Philips consumable shared by the HeartStart OnSite, HeartStart Home and FRx. The FRx Aviation battery (TSO-certified) is a separate part for aircraft use.
How to replace the Philips HeartStart M5070A battery
Replacing the battery in a Philips HeartStart OnSite or FRx AED is simple. Insert the new battery with the arrows pointing down. The device will then run a self-test and provide voice instructions. Once complete, the AED confirms readiness with a “Ready for use” message.
Be sure to record the new battery’s end date to help maintain AED readiness. An AED management program helps you easily track battery status, inspections, and replacement schedules.
The Philips M5070A is the authorized replacement battery for the Philips HeartStart FRx (model 861304) and Philips HeartStart OnSite (HS1, M5066A). It delivers a 4-year installed life and a 5-year shelf life from the manufacturer’s date. The battery powers daily self-tests, weekly status checks, and full rescue cycles. This page covers exact specifications, replacement timing, installation steps, and how to verify you’re buying authentic Philips inventory from an authorized U.S. distributor.
M5070A is the shared replacement battery for both the Philips HeartStart OnSite (HS1) and FRx, the only Philips refill SKU that works across two device families. Sealed lithium with a 4-year install life and a warning chirp at low charge. The standard M5070A is NOT cross-fit with the FRx Aviation Battery (TSO-certified), a separate SKU.

- Common Questions
Frequently asked questions.
My Philips AED is beeping: is it the battery?
Probably yes. The Philips FRx and OnSite chirp at low battery roughly 30 days before full depletion, then continuously when the battery requires immediate replacement. The status indicator on the device front will also flip from green to red. Order an M5070A replacement, install per Philips instructions, and the beeping stops. Don’t ignore the alert; a dead battery means no rescue capability. Average M5070A cost is $249; install life from a fresh install is 4 years.
Can I use M5070A in my FRx AND OnSite?
Yes. M5070A is the only Philips refill SKU that genuinely cross-fits two device families. Same battery works in the HeartStart FRx and the HeartStart OnSite (HS1). This is unusual in the AED accessory landscape; most batteries are device-specific. For mixed Philips fleets running both FRx and OnSite, the shared battery dramatically simplifies refill procurement and inventory. One battery SKU covers both devices on the same 4-year refill calendar.
Is the M5070A really a 4-year battery?
Yes. 4 years installed life is the rated lifespan from the install date (not manufacture date). The device runs self-tests daily, weekly, and monthly that incrementally drain the battery. After 4 years, the remaining capacity drops below safe rescue thresholds and the status indicator flips red. Some operators see slightly longer life in low-use environments and slightly shorter in high-use environments. Plan for the 4-year cycle and replace promptly when alerted; don’t try to stretch beyond 4 years.
Standard M5070A vs FRx Aviation M5070A: same thing?
No. These are two different products despite the similar name. Standard M5070A is for ground-based FRx and OnSite units. FRx Aviation Battery (TSO-C142 certified) is for FRx units installed on commercial aircraft per 14 CFR 121.803. The Aviation variant is FAA-approved for in-flight use; the standard M5070A is not aviation-compliant. For airlines, only TSO-C142 is permitted. For ground-based facilities, the standard M5070A is the right choice at $249 vs $259 for the Aviation variant.
