Only the Energizer Ultimate Lithium batteries are compatible.</P> <P>How old are your Protects?</P> Sun, 29 Dec 2024 20:27:23 GMT Patrick_Caezza 2024-12-29T20:27:23Z https://www.googlenestcommunity.com/t5/Nest-Protect/Nest-smoke-dectector/m-p/665685#M11087 <P>Recently my smoke detector beeps asking me to change the batteries. I have changed them to lithium ones it works for a day and again the second day it starts beeping again. I change it again and that too works for a day. I have checked that the batteries have full power of 1.5 v each. I think this a defective smoke detector.&nbsp;</P> Sun, 29 Dec 2024 01:26:58 GMT https://www.googlenestcommunity.com/t5/Nest-Protect/Nest-smoke-dectector/m-p/665685#M11087 Yorlem 2024-12-29T01:26:58Z https://www.googlenestcommunity.com/t5/Nest-Protect/Nest-smoke-dectector/m-p/665848#M11091 <P><a href="https://www.googlenestcommunity.com/t5/user/viewprofilepage/user-id/634214">@Yorlem</a>&nbsp;</P> <P>What type of batteries did you install?
