3x 1/3 aaa Nimh for L0D CE

m1ruf · Sep 3, 2007

Is it possible to use 3x 1/3 aaa Nimhs in a L0D CE?

There are cells available with 150-180mah capacity all 1,2 volt.

What would the runtimes probably be and would it work at all?

I was hoping the 3,6 volt could let the little photon-cannon shine like on a 10440 lion:thinking:

Why would you want to do that when you already know about 10440s, which have about 320mAh already? :thinking:

I would first try with just two batteries and a separator. This voltage may fit better in the working range of the regulator.

I think 10440 are to dangerous for me! :poof:

:mecry:

If i use 3 1,2 volt /160 mah nimhs in a row I get 3,6 volt current - about the same as with a single 10440 - but just 160 mah capacity is that right?

So the runtime would probably be close to 10 minutes on high assuming that I get an hour an a few minutes to 50% starting output(eyeballing here) with a 1000mah AAA Nimh.

Am I doing the math right?

Or two 1/2AAA cells with no separator... more capacity.

Right.

By the way, didn't I post in this thread already? My post appears to have vanished...

@ Fallingwater: yes I posted the same thread in the "Flashlight electronics section", because initially it seemed like I wasn't getting any replies in here!

@ mods: please feel free to delete the other thread if you feel like it!

What is a seperator?

Any idea about runtimes on high with the 2 1/2 aaa ans 3x 1/3 aaa setups - "guesstiamtes§ are welcome?

cheers

A separator would be a conductive thingie of the shape of a 1/3AAA cell that you put inbetween them, so you can use two cells in a light that would ordinarily accept three.

As for the battery life, a guesstimate could be made if we knew the current draw of the L0D CE on high... do you have a multimeter?

No I don't, unfortunately

But I seem to rember in this thread:

they talked about the current draw, just can't find it anymore
