Lithium Batteries What is a Lithium Battery? It's a battery that uses lithium metal or a lithium aluminum alloy in its negative electrode (anode) and manganese dioxide in its positive electrode (cathode). SANYO's primary lithium battery (CR series) was first released in 1976 and its secondary (rechargeable) lithium battery (ML series) was released in 1989. These batteries meet market needs with their high technology and superior quality.
CR Series Features
High operating voltage of 3V and high energy density
Wide operating temperature range: -40=B0C to 85=B0C (depending on type)
Low self-discharge rate (0.5% per year at room temperature)
High capacity cylindrical type
UL approved
SO9002 certified ML Series Features
High operating voltage of 2.5V
Wide operating temperature range: -20=B0C to 60=B0C
Low self-discharge rate (2% per year at room temperature)
Superior charge and discharge cycle =20 Able to charge at 2.8V=20 =20 UL approved
I was replying to FIRETEK's post. He mentioned lithium. I assumed he (firetek) was referring to lithium ion rechargeable batteries. What I said applies to rechargeable batteries in general though.
You have been given answers to your question, and still want to argue your point.
Either use a battery that the manufacturer reccommends, be it alkaline or lithium or hamster in a wheel connected to a generator.
OR, do what you so desperately want to do and want us to approve of (which no one here most likely will) and accept the consequences. I know what i would do. RTFM and follow the instructions

Picking a battery for a smoke alarm must be predicated on four things:
It's gotta be "cheap"
It's gotta be easy to replace (ie. easy to find)
It's gotta meet the manufacturer's requirements
Whether it's designed to last for one year (or five), the replacement interval must be fixed. We're all "creatures of habit". It's far easier for me to remember my wife's birthday and use a good quality alkaline. If you're bent on using lithiums and you figure you can get five years from the sucker then perhaps setting February 29th as the replacement date might work for you (that comes around every four years). If your smoke alarm consumes more power, you might wind up on the "short" side of the equation, and often with little (or no) warning.
"Broad statements" have gotten more guys into trouble in this Group than Bush at a WMD rally.

Considering this would have "definitively answered" the OP's question, it would have been better to have posted this in the first place.
No actually, most AHJ's recommend that, and for good reason. I wouldn't rely on a "low battery warning" signal from a detector that I picked up at Walmart for $8.95, would you?
Lithium batts. can last 10 years in a smoke. Since smokes need to be replaced every ten years, you can just chunk the whole damn thing when it starts beeping.
This NG seems like its filled with lay-attorneys, (and ministers).
I picked this detector at random, the OP never specified which unit he has. I don't think he is even serious based on posts he's made in other groups.
Yes I would, and do. It also gets tested every other time I cook.
