    Extend your alarm's life at a fair value, minus a few months off Kidde's 2-year guarantee.
  

*by A***R on Reviewed in the United States on July 1, 2015*

I have a 
  
Kidde KN-COSM-XTR-BA Nighthawk Battery Operated Combination Smoke/Carbon Monoxide Alarm with Voice Warning, Intelligent Alarm Technology







  
  
    .When its low battery alert started up, I looked all over for replacement batteries. Seeing that these batteries with Prime shipping would arrive over a week before Home Depot's delivery (being unavailable in my local Home Depot store)... and seeing as how Home Depot also charged $2.50 more for the same product... I decided to order from Amazon.These are AA batteries that come in a 4 pack. The package was brand new. After placing the batteries into the alarm, the alarm went through its test procedure and now seems to work fine. Since the alarm only needed 3 batteries, I'm holding onto the extra.I am docking 1 star because the old batteries, which came with my Kidde alarm, lasted from late October 2013 until late June 2015 when the low battery alerts began - around 4 months less than the 2 years guaranteed by the manufacturer. Still a relatively minor complaint.Bottom line - get these to extend the life of a reliable ~$40 fire and carbon monoxide detector to keep your family and/ or business safe.
