Leapers scope battery - 2032?

[laverdabru]

Due to time off work, been giving my small collection some exercise. Today was the turn of the Webley Junior rifle & a 50's Diana 25(again - am really getting to like it).

By way of contrast, got out the .177 HW35 I bought new a few years back. Had some issues with it, resolved, but it got put away as I preferred an earlier one in .22 or a BSA Meteor/Airsporter for pigeon blatting.

Before it was stored, it was fitted with a Leapers 3x9-40 scope with illuminated crosshairs. Went up to 11, like Spinal Tap amps. On recommision, only 9/10/11 positions produced any illumination, red x hairs.

Out with the multimeter, 2.8v - the CR2032 button battery fitted is meant to be about 3v. Find a couple of spare CR2032's, test them with the meter - 3.2v.

Happy Days! So I thought...tried them both, no light at all. Back to the old one, fine. On 9/10/11 only.

Any ideas?

Try these as they are the same type that my Hawke scope uses. https://www..com/itm/Energizer-Batte...72.m2749.l2649

What a coincidence, my car key fob packed up and I had a similar problem. Old battery dead, new one 3.2V, but didn't work. Head scratching time. Try another battery, fine. Back to the fist new one, I suspect some sort of wax or packing grease, and clean the contact edge on my jeans, try it and it works. Also carefully bent contacts to improve conductivity. David

Thanks for the thoughts - I'll give the 'new' batteries a wipe with contact cleaner. if that doesn't work will invest in some 'quality' 2032's, think the ones I found are cheapo ones I bought in Poundland or similar.

Can you remove the circuit board from the battery housing ? there may be crud in the contacts .





That is the bottom that makes contact in the scope .


1 min into this video shows how to remove one and shows how to clean the circuit board. https://www.youtube.com/watch?v=exdi5V-_s6Q

What a great vid. I am almost hoping one of my illuminated scopes stops working so that I can try it.
Thanks for sharing.
