Anybody know if a pair of these will fit in an incandescent A2 aviator?

I tried them before and they did not fit in mine. I'm using soshine lfp cells. They fit and are a better option

I think 16.4mm is wide as you can go and those are 16.8mm

 

[thermal guy]

I think it's the length that's going to be a problem.

 

[vicv]

For me it was the width. They're too chonky

 

[thermal guy]

Oh. Got ya. I know they are pretty long. If they did fit width wise they would probably be to long as well.

 

[ebuchner]

Ah, thank you all, this saved me the effort of a failed attempt

Any long-term signs that the LEDs aren't taking the slight overdrive well? (dimming, color shift, etc). I'm guessing they're fine because you didn't mention a problem but I figured I'd check as a matter of mild paranoia.

No, there has been no issues. Realistically, the voltage is the same as it would be with two fresh primary cells. They are slightly brighter, but I don't think it will be an issue. People routinely use 3.7 V batteries with no issues, I'm over a full volt blow that. My reasoning with going with LFP cells, is two things. One is that I knew they would fit. Two is that it's safe to discharge them until the lamp turns off. Which would be 2 V per cell. That would be very bad to do with regular lithium ions. Protected would be fine, but a lot of them don't fit.

No. Those are cr2 cells

Thank you for the detailed explanation vicv, this is exactly what I wanted to know

fitment aside, like, if i printed those cr2 to cr123a adapters? the reason i ask is i have a couple dozen of those cr2

 

[vicv]

The problem is with CDR. The lamp draws about 1.5A. Those cells are good for 1A max. And the capacity is half. I mean it's up to you, but for $10 I'd get the right ones
