Tianqiu CR 2032 Don't buy poor lifespan

Soo I'm always looking for a bargain. These appeared to be good quality, as my experience with their alkaline watch batteries was good. The lithium are an entirely different story. These died so fast, even faster than the dollar store, 5 for $1.00 cr2032 batteries.

The weight is one method of determining the capacity, but it's not foolproof. The weight of each of these cells is about 3 grams, matching the Panasonic cr2032 weight, but the life span is very poor, about 30% of the Panasonic, when used in the identical sensor.

So for anyone looking for a bargain, these are not it.
