Cheap and performs accordingly
on December 5, 2010
Pro: The price is right; I haven't found a better deal on 9V batteries
Con: The performance is light. I had these in smoke detectors for about 6-8 months and all went dead within a few weeks of each other.
Bottom Line: If you want a cheap, marginal performance 9V battery, this is the battery for you. I used these in smoke detectors which are wired for power, but require a 9V battery backup -- when the battery is low, the alarm "chirps", and then I replace it. Works fine for this purpose.
If you want long life and performance, you're gonna need to pay more for a better battery.
