Battery with lowest self discharge?

[thinkFlashlights01]

I'm looking for the battery with the lowest self discharge rate possible. I will take any kind of battery. :twothumbs

I'm no expert, but lithium primary, I would imagine. Their shelf life is often 10 years.

Has to be rechargeable, and last for maybe 40 years.

Don't think any batteries will last 40 years. Maybe except for those made by NASA. As for rechargeables, Eneloops and i think Li-ions (except if taken care of badly) last quite a long time.

Then i'm willing to get some batteries from NASA.

Cool. Then try and get an RTG. You have a choice of a few different isotopes to power it, and some will last for many decades. It should produce quite a bit of power and last a long time.

What's an RTG?

Radioisotope thermoelectric generator

The don't seem to be rechargeable (maybe changing the pellet?)

What's your budget?

LOL. If you have to ask...

You're more apt to have a supermodel knock on your door tonight, wearing a bikini and holding a pizza and a 12 pack of beer, than you are to acquire one of those.

Voyager 1 is still going! Launched in 1977, nuclear battery should last until 2020. Ah crap, not rechargable.

RTG's will easily last 40 years. He doesn't have to recharge it.

Better get one quick, though, as I hear the stockpiles of isotopes are getting low and NASA may not be able to build very many more.

lovecpf

A bonus of powering a flashlight with a micro-RTG is that the waste heat would make it an outstanding handwarmer for those colder nights!

I never knew what an RTG was either but I love my new Anorak.

What's it's intended use?

As in why rechargeable and last 40 years??? I mean WTF.... not that many applications that would require to extreme conflicting requirements.

OK I definitely need an explanation on this. I see you mention Anorak all the time, but all I can find is some type of coat. I'm missing the inside joke.

It's a bit like being a geek. Although also has connotations with train spotters.

Got it, but I had too look up train spotters too...LOL guess I'm out of touch! I did see the movie though (Trainspotters)

Guys who turn a simple hobby into a science degree and go well over the top,we call them anoraks.
