Roscoe scores again today with another winner.  He writes: “These lithium smoke detector batteries are guaranteed to last 10 years in a smoke detector.  They’re $7 or $8 at Ace Hardware, but they’re well worth it, and they’ll quickly pay for themselves.  The cost is especially worth it in detectors that are hard to reach or those near bedrooms that might will start chirping in the middle of the night.”

This is an awesome idea, and I’m totally gonna pick some up this week.  I’ve been in my current house two years now, and I’m just starting to see all the batteries go bad one by one, waking me up with that infernal chirping.  And some of them are indeed hard to reach.

Roscoe’s right, you can generally find these locally.  But if you’d like to pick some up online, they’re available in the same price range from a ton of retailers.

By the way, does anyone else hear that bit from Gross Pointe Blank every time you someone says “10 years?”

    I still think that a hard-wired system cannot be beat, and it is one of those things that is worth the price. Especially in a house with three little kids. Come to think of it, maybe these are the perfect backup battery for my wired system–and I didn’t even know that I needed them!

    Just so you know, you’re supposed to completely replace smoke detectors every 7-10 years. So if you get one of these 10-year batteries and it runs down, replace the whole damned unit. Also, if you’ve got some used-to-be-white-but-its-now-yellow detectors in your home, consider them absolutely useless. It takes about 10-15 years for white-ish plastic hanging from the ceiling to “go ivory”.

    Why every 7-10 years? Well, go by the warranty… Some are 7, some are 8, some are 10 (never seen a 9). Over time, the ionization and photoreceptor sensors lose their sensitivity and/or get covered with dust/crap from your shop (no, you can’t just clean them).

    If you do not have a smoke detector in your shop and your shop doubles as a garage, INSTALL A CARBON MONOXIDE DETECTOR! Very important, because people sometimes forget that their cars are running or remote starters malfunction and you can end up walking into one deadly garage.

    Also, if you’re heating your shop/garage/house with propane or oil, absolutely make sure you have them throughout your house. A small propane/oil exhaust leak can make for a deadly situation in the amount of time it takes for you to turn your lights off at night and then (not) wake up.

    Furthermore, if you have a smoke/CO detector in your shop, replace it every year. The sawdust in your shop (especially if you don’t have dust collection) can render an ionization detector/photoreceptor useless in very short time.

  3. Sheesh, Riskable, you must be fun at parties.

    Just kidding, thanks for the useful info.

    I agree with Riskable… I’d rather get out the ladder two or three times a year to replace batteries and check out the detectors rather than trust that a battery is going to protect me, my family, my home, and my property for 8 to 10 years.

    I’m lazy, but not that lazy.

    At least here in Washington’s King County, all new construction is required to use 10 year smoke detectors in addition to a hardwired system.
