AUTHENTICITY
Proof you can check before you buy
Each point links to the page where we publish it: customer reviews, buyers' photos, the data-sheet library, how to reach a person, and our business details.
Check a cylindrical cell yourself
- Check that the claimed model and capacity are realistic for its size
- Inspect the can code and top cap, not just the wrapper print
- Weigh and measure it against the data sheet, and compare voltage and internal resistance across the lot
- Run a capacity test on a charger-analyzer
