I have an aluminum click cmore. I typically use two 357/303 batteries. Recently this scope has taken to killing the batteries incredibly fast. Today I was shooting and put two brand new energizer 357 lith ion batteries in it and literally in less than 3 min the dot had lost half its brigthness, cranked to the max it was barely visible.
On a volt meter both batteries new from the package came out at 1.55+ v as you'd expect. When the dot goes dim, I pop them out and measure again and 1 battery is still 1.55 and the other had plummeted to 1.1v.
This is the 3rd set of batteries that have gotten killed on my very very fast. At first I thought it was bad batteries, but each pair has been bought brand new from different lots and in the last 2 sets its the same story, one of the two batteries is still measuring 1.55 and the other is 1.1 to 1.2.
thanks!
