A 10-Year CO Detector May Operate For Only One Year
A 10-year warranty does not always guarantee
that a battery-powered CO detector will operate for more than 1 year:
operation between 68-86°F may be required for full battery life.
When the batteries die, they may not be replaced.
• If the
batteries are removable, they may be pilfered for use in another
• If the batteries are non-removable, and not
specifically covered by the warranty,
the alarm will be discarded when the batteries die.
Carbon monoxide is invisible and odorless. When CO is detected, and
an alarm sounds, it may be misinterpreted as a low battery signal
and a detector that is not properly secured may be removed and
Many 10-year CO detector warranties do not
include the batteries:
Two Removable AA Batteries
warrants to the original consumer purchaser, that this product
(except batteries) will be free of defects in material and
workmanship for a period of ten years from date of purchase. A good
safety measure is to replace the batteries at least once a year."
Two Non-Removable AA Batteries
Manufacturer "warrants this product to be free from defects in
material and workmanship for a period of 10 (ten) years from the
date of purchase. This warranty shall not
apply to any damage which may be caused by the sealed batteries
used in this product."
One Non-Removable Lithium Battery
Manufacturer "warrants that for a period of ten
years from the date of purchase, this product will be free from
defects in material and workmanship." "The warranty does not cover acts of
God, such as fire, flood, hurricanes and tornadoes or
any batteries that are included with
CO Alarm Features To Look For
• The CO alarm should be powered by at least two non-removable
lithium batteries, and secured with a screw through the alarm into
its mounting plate.
• The manufacturer's warranty should specifically guarantee that
the factory batteries will power the CO alarm for at least ten years.
