My comfort (10 years old)has decided to dial out at 3am every morning to the mobile numbers programmed into it with the message "battery warning" 5 times to each of the 3 programmed numbers
is there a glasgow installer who can help or is it a simple battery replace?
thanks

The Battery needs to be replaced. 10 years is over the life of a typical battery
Comfort tests the battery every 24 hours and if it finds the battery is weak it causes a Battery Warning Alarm. So your Comfort has been testing your battery for 10 years.
You could disable the dial out for the Battery Warning alarm though as a local notification should be enough
You need a sealed Lead acid battery 12V 7 Amp Hours. It is the black rectangular slab you see when you open the case (be careful of triggering a Tanper alarm when you do so

enter your code and pres 3,4,2 for Security Check. This prevents alarms from activating while you test the system

Enter your code then 3 for Security Menu, 4 for Test and 2 for security Check. Dont press # as this will go to the previous menu
Voice should say "Security Check" to show it is in that mode

The recommended life of a battery is about 5 years, this maybe shorter if the panel in in a very hot room 20deg c
I woulsd highly recomment replacing the battery every 4 years

I have plugged in a new battery and when I have tested it through the test function of the Engineer Menu the battery check still fails. The new battery has been plugged in now for a few days and I would have thought it would be now charged up fully. What else could be wrong?

You may just have a knackered battery. With the battery connected up to Comfort, measure the volts across the terminals of the battery - this should indicate if there is a problem if this is well below 12volts
Next, measure the current being drawn from the battery, by removing the +ve fly lead from the battery, and placing a multimeter in between the +ve terminal on the battery and the +ve fly lead
If your worried about doing the above, just have someone test the battery for you or buy another one and replace it.

Also, check the voltage at the Comfort battery connectors without the battery connected. There should be about 13.5 to 14V to charge the battery. If this is not there then the charger circuit is not working and the PCB must be sent for repair

I have done some measurements:
The voltage at the battery terminals not connected to Comfort = 13.5 V
The current from +ve lead to the +ve terminal of the battery = 0.05 mA
The voltage detected at the output of Battery Protection module = 13.5 V

It looks like the Comfort charger is working OK since it is supplying 13.5V to the battery
The next test is to switch off mains, leaving the battery connected
Can the battery power up comfort or does Comfort get switched off?

Ok - I guess there are three possibilities here...
1) Battery is knackered. Although is shows good volts, there could be no load across it with previous test. Re-Measure the volts across the battery terminals when you turn off the main power.
2) A fuse - Not sure if there is a protection fuse (discrete or re-settable) for the Battery Backup. Ident will know, but worth a visual check of the board. Check also for a break in the battery wiring or dodgy connection
3) Problem with the main panel / charging circuit - This will mean a warranty fix or new board

No warranty ,I am afraid, Comfort I is at least 7 years old
But it looks like a bad battery or wiring
Yes check the battery voltage when AC is off but with battery connected to Comfort

Thanks for all your support.
This morning I went to check the battery voltage after I turned off the mains power. To my surprise the Comfort system held sway.
Battery test also now comes up OK.
Can't understand though why suddenly all is good.

I had cases while I was still using Comfort I where I had to do a system reset to clear the battery warning, mainly after an extended power failure.
