Philips HeartStart Home and OnSite AED Defibrillator Long Life Replacement Battery, M5070A

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

Fits just right. More $ than I thought, but as advertised.

Keeping our HeartStart current & ready to use if needed

Always been good. Great pricing.

I suppose these batteries work well. I have a home defibrilator, but I've never had to use one. I also hope I never have to use one, and I'm getting to the point where I don't want to be resuscitated if I ever have an incident, and the price of these batteries will weigh in my decision. I wish the companies selling the batteries would also offer ways of recycling them.

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.

I purchased 2 of these long life batteries with 4 year warranty. Soon as they arrived, I put them in my Phillips AED. The first one passed the self check no problem. However the second failed multiple times indicating "Low battery, replce battery". I immediately got on to my amazon account to request a replacement. Nor replacement or return is an option. What am I supposed to do with what's supposed to be a brand new long life battery that is dead? Again, I purchased two of these. The one passes the self test no problem. The second failed every time. I call Amazon who advised that these batteries are non returnable. So now I have to get with the company directly, or try to figure out how to use the four warranty. Very frustrating! In the meantime I have a AED that is down.

We wanted to replace our defibrillator battery with one that is of an OEM quality. The battery has a future use by date of 6 years from now and the defibrillator went through the testing process very well.
