Reviews about ULTRA LIFE, 10 year, smoke alarm battery, U9VL-X
| 47 of 49 people found the following review helpful  Ultralife 9-volt lithium battery life in smoke alarms and carbon monoxide detectors, This review is from: ULTRA LIFE, 10 year, smoke alarm battery, U9VL-X (Tools & Home Improvement) To clarify some of the other comments here, the Ultralife 9-volt lithium battery is designed to operate an ionization-type smoke alarm for 10 years. The packaging for the Ultralife U9VL-X 9-volt lithium battery indicates that it's a smoke alarm battery. It will not power a carbon monoxide (CO) alarm for 10 years since a CO alarm operates at a higher current drain than a smoke alarm. Also, the sensor in most CO alarms is designed to operate for 5 to 7 years depending on the brand and model, after which the entire alarm has to be replaced. While the Ultralife battery should outlast an alkaline battery in a CO alarm, and other devices, by 2 to 3 times, don't expect it to last 10 years in devices other than ionization smoke alarms. 24 of 25 people found the following review helpful  10 Years - probably*,  This review is from: ULTRA LIFE, 10 year, smoke alarm battery, U9VL-X (Tools & Home Improvement) * Assuming you have smoke detectors that are hardwired to AC, with battery backup (your 10 year cell). Since the AC will be running your detector 99% of the time, a long "shelf life" battery is just what you need to not mess with the dumb things too often. Although, be prepared to wedge the things in there - depending on your model this can be a tight squeeze. And taking it out if it was, may involve the use of vice type pliers. 39 of 44 people found the following review helpful Lithium Batteries Are Good For High Ceiling Smoke Alarms, This review is from: ULTRA LIFE, 10 year, smoke alarm battery, U9VL-X (Tools & Home Improvement) I can't comment on this particular battery, but I will comment on this subject generally. We have 7 smoke alarms in our house -- building code overkill. One of our ceilings is 14 feet high. There is much more danger that I will be seriously injured in falling off of a ladder by replacing that high ceiling battery once a year than I will be injured in a house fire. But no one thought of the big picture or asked me when they built my house. And when that high ceiling battery starts to chirp in the middle of the night because it is low, forget about getting any more sleep. And you will be in fine condition to climb a tall ladder in the morning.Lithium batteries should last 5-7 years, so that means I subject myself to falling from a ladder to one-fifth or one-seventh as often compared to regular batteries. Just be careful. Radio Shack makes Lithium batteries, but they are larger than normal 9 volt batteries and might not fit into your device. |
