Dielectric grease with DPP

[racer-x]

I just got my first Deltapoint Pro optic and it came with dielectric grease on both sides of the CR2032 battery. I understand what dielectric grease is, but have never seen it used in an optic.

Anyone have experience with this and use it in your optics?

I use it on my optic batteries because it was recommended by a few others that have been using it for years on there open guns. Don’t know if it’s right or wrong, but  haven’t had any issues using it. I change my batteries every 6 months which might be to often but don’t want to change one at a match.  Also have better luck Duracell batteries.

Thanks Jeff.

Before every match now, I check battery voltage in my RTS2's and replace if less than 3.00v. Had dot problems 2 times that a new battery fixed. The problem batteries were 2.89 & 2.92v when I checked them after match. Replacing if below 3.00v has helped my match reliability, but works out to changing 2032's every 3-4 weeks.

Duracell's seem to be best in my experience as well. More consistent starting voltage compared to others I tried.

 

Not sure if the dielectric grease will promote a lower impedance connection in use. Worth some experimentation though. I have noticed that the battery is pretty scuffed up from recoil by the time I replace it in RTS2.

DPP owner here as well, and I concur that the Duracell’s seem to be the best. I have never used dielectric grease though I’m sure it does help to a small extent.

Doesn't hurt to apply a little.

I use it on my boat trailer light connections, no corrosion.  I would assume woks the same way on any battery connections.  Nothing worse than corroded connections or batteries.

dielectric grease is an insulator.  Why would you apply it to your battery connections?

Interesting article, very informative.

I've used them on my RMRs since there is no fully enclosed battery compartment, applying it over the base of the optic/battery. Never thought of using it on the DPP.
