Batteries for Smoke Detectors: The Importance of Choosing the Right Smoke Alarm Batteries

It’s the middle of the night, and your smoke detector starts beeping—not because of a fire, but because the battery is going dead. It’s called a “nuisance alarm,” and we all do the same thing: We’re not going to search for smoke alarm batteries at that hour, so we remove the battery and go back to bed.

The new battery may not ever make its way into the detector. Batteries for smoke detectors are not a lot of fun to replace. They’re way up there on a wall or ceiling, the ladder’s out in the garage … it’s just too easy to ignore unless you do it right away.

There is a strong reason to not forget about your smoke alarm batteries. An estimated 40 percent of household smoke alarms have missing or dead batteries, and missing batteries—removed to silence a nuisance alarm—were a factor in nearly 350 residential fire deaths last year.* That trip up the ladder sounds a little more appealing now, doesn’t it?

Fortunately, Medic Batteries offers a battery that can stop nuisance alarms and preserve your safety for a decade. Ultralife lithium smoke alarm batteries last five times longer than alkaline and 10 times longer than carbon-zinc. One Ultralife 9-volt battery can keep ionization-type detectors up and running for 10 years, which is why they are original equipment in most premium, long-life smoke detectors.

With Ultralife, you’ll spend less money on batteries for smoke detectors and less time replacing them. And with Medic Batteries, upgrading every detector on you own is easy and affordable. We offer discount bulk battery packages and same-day shipping, so you’ll get the best price and be safe and secure in no time.

Medic Batteries takes batteries—and your safety—seriously. Spend a little time to check your smoke alarm batteries. If they’re old, are missing, or simply don’t say Ultralife, call us at 1-800-479-6334 and let us give you the security only Ultralife can give.
