No batteries are required to operate the sight. The lifespan for tritium is measured in half-lives. The half-life for tritium is approximately 12 years, meaning that it will still be at half its original brightness at the end of 12 years.

You’ll wonder how you ever got along without this tritium sight when you’ve tested it a few times at the range.
