Stop the Beeping
Holy cow, this AED beeps every 10 seconds once the battery goes low! Glad to get this replacement battery, although it’s pricey.

Life Battery...
Seller delivered item as expected; it was packaged well and is as described. A bit on the expensive side, but works as expected and the last one that I purchased lasted quit a long time, but failed to label when I installed it. This time I did so I wouldn't forget when I installed it.

Name brand equals restful nights
Went with the name brand here due to the nature of the device they power. Didn't want a possible failure of an off brand on my conscience. The extra cost means I can sleep better at night. Simple installation.

Did not last a week
Save your money and look elsewhere. Did not last a week and the machine started beeping with low battery!

Well, it fits
Hard to do an honest review, since I've never had to use the AED to shock someone, but the battery is an exact fit for the old one, and the AED self test checked out after installing, so hope its good. Hope it lasts longer than 5 years, as they are expensive, but sure don't want a dead battery when/if you do need to use the AED. 1 Star off for the excessive price, but can't complain otherwise.

Ottima
La batteria di ricambio Philips M5070A è il componente energetico vitale per i defibrillatori HeartStart HS1 e FRx. Trattandosi di un ricambio originale, garantisce la massima affidabilità e una perfetta integrazione con i circuiti del DAE, assicurando che il dispositivo superi sempre i self-test quotidiani e sia pronto all'uso in caso di emergenza. Questa batteria al litio biossido di manganese è celebre per la sua lunga durata: installata in un dispositivo in modalità stand-by, offre un'autonomia di circa 4 anni. Inoltre, è progettata per erogare fino a 200 scariche o garantire 4 ore di funzionamento continuo, prestazioni fondamentali durante un intervento di soccorso prolungato. La sostituzione è immediata e non richiede attrezzi; una volta inserita, il defibrillatore esegue un controllo automatico per confermare lo stato di operatività. Acquistare la batteria originale Philips è l'unica scelta responsabile per chi gestisce la sicurezza in ambienti pubblici, sportivi o aziendali, dove l'efficienza del dispositivo non può essere messa in discussione.

Attention à la procédure de reset
Lors du changement de batterie, l'appareil opère un reset qui est très lent. Bien patienter jusqu'à la fin de la procédure, sinon l'appareil continuera à considérer que la batterie est à remplacer en émettant des bips à intervalles réguliers.

Guarantee?
Purchased 6 batteries for our sites in November 2023, we have had to replace 1 of the batteries this month (February 2025) so for a battery that had a 4 year 'guarantee, that has lasted just 15 months at £175.00 each. However, a small price to pay for soemone's life.
