Dug out 2 old PA30mmRD-AD optics.

The internet is failing me.

What batteries do these take?

Internet tells me 2032 which is not even close.

Thank you.

Possibly a CR-1/3N battery?

Pic of the optic?
If it's the one I think it is, CR123.

I haven't uploaded a photo on 10 years.

A CR2 is *just* too large in diameter.

These were the common optic everyone had 10 years ago.

Edit, found this.

Edit again.

Found it as LR44.

Thanks guys.

Are you sure it's an LR44?

I'm 100% positive that I've been using 1/3N batteries on these red dots, and I have several of them.  It's the same battery that Aimpoint uses in the PRO optics.

Correct.

1/3N  with the LR44 as an acceptable short term replacement.

1/3N is correct and more specifically the insulated type batteries to prevent grounding.
