Authenticity

Proof you can check before you buy

Each point links to the page where we publish it: our Loox reviews, buyers' photos, the data sheets we host and our business details.

Check a cylindrical cell yourself

  1. Check that the claimed model and capacity are realistic for its size
  2. Inspect the can code and top cap, not just the wrapper print
  3. Weigh and measure it against the data sheet, and compare voltage and internal resistance across the lot
  4. Run a capacity test on a charger-analyzer
