MTI Safe-T-Alert CO detector

[Roc]

Hi all,
I installed an MTI Safe-T-Alert CO detector in my aft cabin, SB side, on the teak trim up by the ceiling.  This past weekend, it sounded an alarm. We did not have the engine on and there was nothing used that would emit CO.  I called MTI and told them what happened and they said occasionally, the gases from a charging battery may cause the alarm to sound.  Now I did check my battery earlier that day, by looking into each cell.  It was raining, so the boat was closed up for most of the day.  So it seems like it was the battery gases.  

Would like to know if anyone has this unit installed and if they had any false alarms (particularly when charging or checking batteries).  I'm thinking this was due to the closed up boat because of the rain and by lifting the sette cushion and checking the batteries??  Any thoughts would be appreciated..

Thanks!

Sure did.. Installed a Kidde model KN-COB-B and the darn thing wouldn't shut up unless I put it outside.  That of course does me no good.  I Moved into my RV and it doesn't sound off.

I took my RV CO detector to the boat and lo  it works. :confused:

I wrote to Kidde and they also mentioned a charger being a possible cause.

So I guess I'll just exchange units and forget about solving the problem regarding the charger.
