Rating: - If it last 10 years....then great!
Otherwise...even if it last 5 years in my smoke detector, I am well ahead of the cost curve and forgeting to change out the typical 9v every 6 months.
Rating: - Is it nuclear?!?
One Ultralife 9v has powered my portable headphone amp for almost 40 hours and it's still going strong! This is normally a 10-hour stint with a regular 9v alkaline battery. Not cheap, but I can imagine 5x normal alkaline life with these lithium powerhouses in low-drain electronics.
Rating: - wonderful product
if you're sick of changing those smoke alarm batteries every year, this is the product for you. works very well.
Rating: - As Advertised
A long life battery to make changing the battery in my not easily accessible smoke/fire detector as infrequent as possible. Very satisfied with the "Ultralife 9v lithium battery" which lasted approximately 4 1/2 years. Excellent!
