De Energizer come quickly and well packed in an envelope
Practical application persistence
*************************
In my smoke detectors, it has been so that this always started at shorter intervals beeping although full battery waren.Das lies in the greater voltage fluctuations of batteries. After researching on the Net and Amazon I went to the Energizer Lithium 9V come. All smoke detectors with these batteries fitted. Since the rest is no longer beeps and the shelf life is here with up to 3 years, of course, much longer than conventional batteries.
Conclusion
****
