We got 2 for Xmas 2 years ago,1 was hard wired no problems, the other battery operated, was fine the first year ,after that the batteries had to be changed almoest every 2 months and when you tested the batteries said they were goo,but would work untill you put brained new batteries in it,costin more than its wourth to keep it going,not sure if its defective or not .can someone help.
I am seeing the same problem in 2 units out of the 6 I have. The batteries are draining VERY quickly (in around 2-4 weeks from brand new batteries being added). I am using the recommended brand of lithium batteries (surely that cannot turn years of usage into weeks? But still...) and yes, the batteries are installed correctly and brand new.
I have purchased a new unit and it is happening to that too, but the 3-4 other units I have in other rooms are fine.
I'd also welcome some advice. I assume they are just defective? But if so, 2/6 is a very poor ratio.
I have the same issue with several of my Nest Protects.
They vary in age (4-6 years).
I purchased the recommended Energizer Ultimate Lithium L91 batteries to replace the empty batteries.
3 weeks have passed and i had to replace the batteries AGAIN.
I bought a new batch of L91 batteries, 4 weeks passed and the batteries were emtpy again!
Any advice would be welcome!
