I mean non-rechargeable lithium batteries. I recently learned that they are available in 1.5V AA packages. But I thought the battery chemistry determines the voltage, and lithium produces 3V? How do they get it down to 1.5V?
And how long have those been around? I don’t think I’ve even seen them in Japan yet.
i don’t believe that chemistry decides the voltage. i mean, i think 9V and AA batteries (of the same brand and special type (alkaline, whateva- ‘special type’)) all use the same chemistry.
it’s the amounts of the chemicals, the proportions and all, and the spacing of the battery elements. i think.

Sorry, I guess I should have said the chemistry determines the voltage of a cell. A 9-volt battery is made up of six alkaline cells connected in series (1.5V x 6 = 9V). But a single lithium cell is 3 volts, isn’t it? How do you get 1.5V from that? If it’s a different chemistry, why is it still called by the same name?
I wanted to know that myself.
My wag is that lithium is one side of the battery, usually paired with X. For these 1.5V batts they use Y.
Not very helpful, I know.
According to this page at Energizer (far right column), k2dave is right, and X = MnO[sub]2[/sub] and Y = FeS[sub]2[/sub].
