Title: First Alert SCO501CN-3ST Combination Smoke and CO Alarm
Review: Easy to install and works as advertised. Power/Smoke LED very hard to see and flashes white not green. Have to be in complete darkness to see. Comes with Energizer E91 AA batteries, which, Dec. 10 Consumer Reports, rates below average. First Alert Customer Service very specifically recommends only the Energizer E91. They do not recommend any other brand or Energizer lithium batteries. Don't understand their reasoning. Had the alarm about a month so can't comment on the life of the batteries.
