Well.

Some years ago, BG sent me a free CO detector.

This morning it started chirping on the grounds that the battery was at "end of life".

On the unit is the statement that the unit should be replaced by "November 2018"

Now, either this was a pretty damn good estimate. Or the unit actually has a clock/timer/calendar built into it.

Now, I can hardly believe that something like this would actually have a timer in it (Especially since I am sure I had to pull a tab from it in order to activate it which presumably closed the circuit on the battery)

But even so...

To the day! :p
 
Aye bro, I had 2 chirp on the same day as they had also run out as dated.
I think it also figures in the photocell sensor life as well. (something like that)
 
Our CO alarm started sounding last night for 2-3 mins so booked in a boiler service but it's over a week away. I guess the fact that it's working and not currently alarming is a good sign, but can't exactly turn the boiler off for a week.

In the meantime I'd buy another one that shows the max level measured and keep a close eye on it.
 
If the alarm has a replace by date, follow it.

The sensors in them degrade over time, the date printed on the alarm is the point where the sensor can no longer be considered reliable, it'll probably work fine for a while after that*, but it's really not worth taking the risk.

*The manufacturers tend to play safe, as they should with stuff that is meant to save lives.
 
IIRC my all of CO alarms basically committed suicide when they got to their expiry dates. There certainly wasn't an option to silence the warnings and leave them running.

The warning for battery replacement was different
 
I'll do you a favour and recommend you buy an Aico CO alarm as a replacement. There's tonnes of manufactures out there on Amazon, but Aico are one of the top brands for smoke alarms etc.

Lithium battery:

Both of these have audiolink which is pretty cool. You can download an app, tap the button on the device a couple of times, and it blips and bloops for a few seconds transfering all the data over to your phone using its microphone. You can then look at stats for alarm triggers, CO levels etc.
 
As an aside, my CO monitor always shows a reading of 0. I've even tried putting it right by our wood burning stove and it stays at zero. My understanding is it should at times register some sort of reading (as levels are never zero, and especially in the proximity of some appliances is a lot more than zero but still safe levels), but it never does.

Any chance I have a dud? This is the model

This is actually a sealed unit, the batteries are not replaceable.

The thing that got me was how it died on the day!

Literally, On the day!
