Smoke Detector

[GraemeW1]

Hi my batteries have expired on my smoke detector. Can I use Alkaline or do I have to buy Lithium batteries? My model is unwired.

Thanks for you help

Hi @GraemeW1 

According to the support site, they require Lithium batteries.

Both battery and wired Protect require Energizer Ultimate Lithium AA (L91) batteries.

Don’t use rechargeable or alkaline batteries. If you do, they will quickly drain and will need to be replaced soon after installing them.

• Using other types of batteries than the ones recommended by Nest will be detrimental to the smoke and CO alarm operation.
• Don’t mix and match batteries.
• Don’t place new batteries in with old batteries.

Protect (Battery) requires 6 AA batteries. Protect (Wired) requires 3 AA as backup batteries. Wired Protects will use backup batteries if there’s a power outage.

Hello @GraemeW1 , 

Thanks for reaching out. Alkaline batteries will get drained quickly, and it is recommended to use Lithium. You can check out this link for more information.

Hope that helps! 🙂
