Lithium batteries?!

Thread Starter 
Sorry if this is the wrong forum but I didn't see a more appropriate one. I was at Best Buy the other day looking for a good set of AAA NiMH batteries, when I noticed a substantial section devoted to...lithium batteries! And I don't mean wristwatch lithium cells, I mean AA, AAA, C, even 9V form factor lithium batteries!

Like, whoa. Is this a brand new trend? Or have I just not been paying attention to the battery scene? Which battery type is better, NiMH or lithium? The AA and AAA lithiums were 1.5V.

Are the lithium batteries rechargeable?

NiMH are better because you can recharge them. but the lithium disposible batteries are much more powerful.

ya chances are those Lithium battieries are not rechargable... Lithium Ion batteries are rechargable but require very complex specialized chargers which is why you dont see them in common (AA AAA 9v) formfactors and only in notebooks and such

My Rio Karma uses LiIons, albeit not in a common standard formfactor. It's pretty common in smallish electronics such as MP3 players and cellphones, not just big things ike laptops.

well but still, its not a standard size, its special cause there is a very specialized charger in there that knows the specs of the battery

rechargable lithiums are, AFAIK, always 3.7 volts (or a multitude).
AA/AAA is 1.2 or 1.5 volts, so the ones you saw are probably not recharcable.
Very powerful though, those non-rechargables, as others here stated.

Extremely long shelf-life too, if I recall correctly. Good for devices you won't be using too often, e.g. smoke detectors. Sounds like they may be decreasing in price and increasing in popularity. 'Bout time alkalines got knocked off the perch by a better disposable technology.

My surefire light uses lithium batteries and they have a shelf-life of 10-years

WOW.. I had no idea you could get disposable lithiums!!!! Can use them everywhere we use alkalines? If so, this is the best thing since sliced bread...or Grados.

Yeah, I saw some Energizer ones with a 15 year shelf life. They last about 7 times longer than normal Alkalines.

I'd get some in a shot for my SM3 amp if they were rechargeable. Rechargeable lithium cells can be charged anytime and its impossible to overcharge them.

In fact I bet manufacturers are working on Rechargeable Lithiums...
