Default Trying to find aa sized lions that can ouput 1.5 volts

Hi guys
I've been searching for a while for this. Can someone help me find a AA battery that is high drain like the lion cells we use but is 1.5 volts. Also could this type work in a nitecore charger. My dad needs this for a camera that takes double A's but it drains too fast.

Thanks for any help.

No sorry I meant rechargeable.
But thanks for the help. Forgot to mention that....I have a fever and am quite out of it.

You'll need a charger that can charge 1.5vs though.
These are NiMH and I'm looking for rechargeable lithium ion or lipo. But thanks.

Maybe a dumb question. Would there be issues running these in series?

Yes. Cameras cannot operate at 1.5V.

Lithium-ion batteries are inherently incapable of operating at 1.5V. The specific voltage of Li-ion is 3.7V; any batteries of this chemistry that are charged below 2.7V are permanently damaged. So you cannot have a 1.5V Li-ion - you need to use another chemistry.

Default Re: Trying to find aa sized lions that can ouput 1.5 volts

You could try NiZn AA cells. 1.6 volts, not the highest capacity, but very low internal resistance so they work great in high drain applications. You'll need a charger made for NiZn though.

NiZn may kill some devices because they're higher voltage than most devices are built to accept. So I would advise against using them unless the device in question has been properly tested for use with NiZn cells.

Explain the ones I linked above then.

I know, internal regulator circuitry.

Bullshit. Go measure the voltage of a fresh energizer lithium and you'll see it's around 1.8V. There are zero accounts of energizer lithium killing devices that I'm aware of. The 1.6-1.7V of a NiZn is even less harmless.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

To be fair, he's right 99% of the time as far as I've seen...

I know, that is what surprises me too, but I caught him once
