Can anyone remember off the top of your head what battery the AP right angle scope for polar alignment uses?

Hi Jim,

Mine came with two GP A76 batteries.

The illuminator ships with two GPA76 button-style batteries pre-installed. These are 1.5 volt alkaline batteries that can be found under different manufacturer product numbers through cross reference charts.

What about the Energizer #357 / 303 batteries ? They are 1.55 V silver oxide, but I believe that they are physically the same size.

Jim's question inspired me to check the batteries in ours, and they were dead. (I apparently left it on.) I had a pair of working LR44s.

Just added some spares to my shopping list. Keep lots of CR2032s on hand, but not many of the less needed button battery varieties.

You know, somebody could make a lot of money if they could just invent a red cross her finder scope that turns itself off when not in use like my Target rifle.

That would be cool ! I have lost track of how many times have left my illuminated reticles turned on. That is one thing I really like about the RAPAS. Since it is using only Polaris as the alignment star, it is usually bright enough that I can see it when there is still a little daylight, and I do not need to turn on the reticle. There was an older version of the PASIL on my old 800 mount that used Polaris and Delta Ursa Minoris for alignment, but you had to wait until it was completely dark to see the Delta Ursa Minoris, and the reticle had to be turned on.

You have to plan ahead for illuminator usage…

If I go to a five night Star Party, I take five batteries.    It works out perfectly!    <G>

Not as good a solution as timed shutoff, but since Telrads are large I have drilled a hole in the side of the ones I have and put in a red LED  --  makes it harder to accidentally leave it on when you don’t want to.

Has anyone experienced battery leakage damaging the contacts?
