First Alert Model CO400 CO Detector..........instructions suggest "standard" 9 volt battery and give Duracell MN1604 and Energizer 522 as suitable replacements. In the next paragraph it warns not to use any other batteries.
Today the low battery alarm went off after only 8 mos. The battery that came with the unit was an Eveready 1222 and apparently not alkaline. I got the idea from that fact that "standard" might mean non-alkaline. But the Duracell and Energizer are apparently alkaline. A call to First Alert was not impressive.
Perhaps I put words in the rep's mouth but she confirmed that "standard" meant non-alkaline and suggested shorter lives for other batteries. She didn't mention that any harm would be caused.
Is there any apparent reason why other brands of alkaline batteries would not be suitable?
