Frequently Asked Questions
What is the difference between protected and unprotected 18650 cells?
Protected cells include a small circuit that guards against over-charge, over-discharge and short circuit. Unprotected cells are slightly shorter and are used in devices or packs that provide their own protection. If you are unsure, choose a protected cell.
Button top or flat top — which do I need?
Some devices and chargers require a button (raised positive) top to make contact, while series battery packs and many mods use flat tops. Check your device; if in doubt, contact us before ordering.
Can I buy 18650 cells in bulk?
Yes. We offer wholesale pricing for 50 and 100 unit quantities. See our wholesale batteries page or request a quote.
