    I have been buying these from some time now. They SEEM to be more expensive then the lower end batteries, however due to the extended use you get from them, the 'long term cost' is MUCH CHEEPER then continually buying the lower end batteries. WELL WORTH the price.

    This installation was in a 1941 house with a very heavy wood door. The new opener track mounted higher than the one being replaced. Also, the old one installation did not have the safety beams at the door sides. Those issues combined with the regular installation steps required more time than what was originally thought. I am extremely pleased with the door's operation so far. The opening speed is incredible for the door to be as heavy as it is. I am glad I spent the extra money and purchased this model. P.S. Genie does NOT have the manual available online and will charge you for a replacement if you lose yours.

    bought these for a smoke alarm in hopes of staying off a 10' step ladder at two o'clock in the morning, dead in seven months, the batteries not me.

    Not much to say, this 9V battery works as intended; the price seemed high, but I haven't purchased this type of battery in a long time.

    The Energizer Advanced Lithium 9V batteries boast a 10 year life for AC-powered smoke detectors. Although this is more expensive than a typical 9V battery, those typical batteries last about 6-12 months. At about $8.50 per battery, it costs under $1 per year per smoke detector to keep my family safe. I've only had this battery installed for a month, so I don't know if it will last the full 10 years. But it only needs to last at least 2 years for me to break even. Be warned that the battery is very rectangular. Normal 9V batteries have rounded edges, so it may be a tight fit (or might not fit) in your smoke detector. Open only one a a time; if it doesn't fit, at least you can return the unopened ones.
