Battery Question

[icewolf08]

Is there such thing as a 1.5v rechargeable AA size lithium-ion battery? I would love to have a replacement for some NiMH batteries, as they don't perform so well in the cold. I could go with the straight Lithium batteries, but I would love to save some money and save waste.

By straight lithium do you mean Lithium-Polymer? I'm not familiar with straight lithium batteries. What application of cold use do you have anyways?

I believe we have same cold application in the NE as he does over in Utah.
I believe they call it winter.

My theatre has forced hot air.

My house has forced hot air.

My car has forced hot air.

The outside doesn't have forced hot air, but I don't do theatre outside, or live outside. Now for those brief walks between heat? My iPod Shuffle has an internal battery. My cellphone has a battery pack, my watch has a watch battery.

What needs AAs?

Did it occur to you that there is life outside the theatre? I am going to keep you guessing for a while though, it is fun!

In any event, I don't really care what kind of lithium battery as long as it is 1.5v AA size and rechargeable, I want to know if such a thing exists.

I've only ever had experience with NIMH versions, but at up to (what is it I have?) 2500 mAh, who can complain?

Edit:

Just checked, yep, 2500 mAh, but at 1.2 volts each? Weird... how does it work? haha.

CRV3 batteries are a 3 volt battery designed to replace two AA's side by side. Here's a link I found . Don't have any myself but it's a cool idea.

have you ever tried to use them in the cold? Ever wonder why people keep Alkalines in the fridge? It slows the reaction. This is great if you want to store the batteries, but try using them in the cold and they just don't work. So, the lithium batteries like the Energizer E2s work much better in the cold. So I want to know if there is a rechargeable that will work well in the cold.

From a website I came across just the other day

Are Lithium Ion batteries available in standard sizes like AA , C or D cell size?

No, Lithium-ion batteries are not available in standard sizes. We believe this is because it would be too easy for users to inadvertently put them in a charger not designed for Lithium-ion batteries creating a potentially dangerous situation. (If an alkaline battery is put into the wrong charger it might leak or even burst, but a lithium-ion battery put into a NiCd or NiMH charger not designed for lithium-ion, might ignite. Also, because Li-ion batteries operate at much higher voltage (typically 3.7V per cell) than the 1.2 to 1.5V of most cell batteries, designing a 1.5V lithium-ion cell would be expensive.

I was watching a show on the history channel the other, all about batteries. I t was fascinating! A couple of students and a professor from Tulsa University, were awarded an US patent last year for a Nano-Li -ion battery. Even at the nano level a Li-ion battery produces 3vdc. The Professor said, " of course at that size, we're talking about Pico-amps" but it's still 3 volts. Amazing.
If you get a chance to watch this show, do. It's fascinating, 'specially the part about them building these "nano-batteries".

Lithium Ion will soon be rendered obsolete by the newly improved Silver-Zinc batteries.
