How long does the battery last? Can the alarm be set for any oxygen level?

The life of the batteries (two AAA) depends on how often the Pulse Oximeter is used. I don't know about setting the alarm as it defaults to below 93% and that is the level we are monitoring.

Original battery supplied by manufacturer was gone quickly in less than a month. New ones are holding on. Did not play with setting alarm for oxygen levels.

We are using the preset alarms, but yes. The batteries that came with the oximeter only lasted about a month, but we are using it a lot right now. Simple battery replacement with AAA.

Haven't had to change battery . I have had my unit about two months and really like it.

You need to replace battery maybe once a year. My last CO detector lasted about 10 years. I expect this unit to last 5 to 10 years. I like this unit because the warning is in a human voice instead of a sharp alarm.

You don't...it's like a clock, always on. Runs for a couple years n the batteries unless you continually let the alarm run.

There is an internal battery that allows the alarm to operate for some time. The siren in the base unit will sound, but not sirens plugged into wall sockets. I have mine plugged into a UPS, and know it will operate at least 24 hours. It worked fine for me during the last power outage.

HelloThe detector runs on battery only. It has a 10 year battery built in. Also has test button to test the alarm. Hope this helps.

The alarm goes off for about 20 seconds and resets itself. It has the power to reset itself, but leave it on for 24 hrs (three nights) and the batteries about dead.

I have the eight hour battery and get eight hours of oxygen but I am only on 2 liters. The higher the liters the less time you will get on the battery. You probably wouldn't have to change as often on the 8 hour battery.

I set the timer on my DX6i controller for 5 minutes. When the alarm activates. I end the flight.It seems to work for me and the batteries have lasted a long time.

Yes, the alarm is AC power. The battery is only meant for the possibility of a power outage. The battery only last for the 36 hours after the alarm is triggered, but I don't know how long the battery last if it is not sounding. Since there is only pull on the battery after the trigger, I am guessing that the length of the battery life is as long the battery itself. I have one more thing to tell you. This thing is pretty loud when it goes off if you haven't heard it yet, so you'd definately be able to hear it...probably in your neighbors basement!If you have anymore questions, don't hesitate.

Battery life depends on how much time unit is in alarm condition. If it never goes off, they'll probably last a year, but it also depends on the batteries and the environmental conditions.

Have not had to change a battery yet, of the first three I bought. I have seven now. If it is really windy, the one on back porch screen may go off, but, they reset. I love these alarms.

Not readily apparent. You will have to contact the manufacturer. I replace the battery in my alarm system every 5 years regardless of whether the battery has failed or not, and I have had two of these batteries last the full 5 years.

Just to add a bit more. I wear it to wake me up at night if my O2 drops to low. You can set what % the alarm goes off at. I spent 3 days last spring in a coma when my O2 crashed in my sleep, this meter wakes me or my wife up before that happens again. Pin point accuracy isn't important for me as long as it saves my life, which so far, so good.

This unit probably detects CO at less than 30 ppm, but is not allowed to display that level unless a button is pushed. In this case, the peak level the alarm detected since last reset is what will show, not the current ambient level. From 30 to 70 ppm, the display can show the ambient level, but the alarm will not sound until it's been in that range for 30 days, as mentioned. At 70 ppm, the alarm is not to sound for at least an hour, and no more than 4 hours. That's UL requirements, which most codes across the US adhere to.

All smoke alarm batteries should be changed every 6 months according to my fire department. It eliminates them beeping during the night as the batteries die down. Some other models offer batteries that last ten years- very expensive but may be worthwhile if the alarm is out of reach such as in a great room ceiling.

I do not think so. When it stops working I change the batteries. I never heard an alarm

No. This has automatic shut off. The battery duration is a problem. It cannot be used to record oxygenation continuously or even at intervals during sleep. iHealth confirmed that this is designed for spot use only.
