Where can I find a replacement battery for my 8 x 50 illuminated finderscope?
The 8×50 Polaris finderscope used a PX-14 mercury battery. Due to EA disposal laws, mercury batteries are no longer legal to produce in the United States. Unfortunately, no battery manufacturer has made a replacement 2.7V battery in this size. PX-14 batteries may still be available through mail order or internet battery retailers.
