Will a dead RCR123A act as a filler

[LGCubana]

The title asks it all.

I'm looking to do a CREE upgrade, to an incandescant that originally used 3X3.0v primaries.

My goal is to use 2X4.2v RCRs instead.

Do I need to buy a dummy CR123A or will a dead RCR123A (that reads 0.0v & can not be charged) work as my filler ?

There is only one good place for dead lithium cells: the trash.
And the worst possible place for them to be is in a working appliance.

Either buy a proper spacer or build one yourself (it's easy with a bit of wood and some wire).

Do not use a dead cell - think AW sells CR123A / 16340 size dummy cells - think you can also buy them at Lighthound.

You can also get them here, UK.

Or, you could just use a pair of 17500s.

... or a pair of 18500s if the diameter will fit.

To add from what I have learnt here, the main cause of problems (fires, explosions!) with lithium batteries (primaries, but may apply to RCRs as well) seems to be when the voltage between two is mismatched and one ends up trying to charge the other, so DEFINATELY dont use a dead one in there.
Also if your RCR is dead, i dont think it will actually provide an electrical path anyway, so apart form the dangers, I dont think it would actually work.

Nooooooooooooooooooooooo.

Bad idea.

A 0 volt RCR123 is dangerous unless it is in the trash.

 

[LGCubana]

Dummy it is. :duh2:


Thanks for the replies

LGCubana, if you haven't already bought the R123s, you should consider posts #5 and #6 above. 2 x 17500 cells will fit in the same space as 2 x R123s + a dummy R123. Both combinations are 10 cm long, but the 2 x 17500s will give you >1.5x the capacity. If 18500 cells will fit (check the internal diameter of the light) they would give you ~2x the capacity.

Don't use it, don't trash it, RECYCLE it.
