Why Used

These are genuine G3 batteries that have been reconditioned, inspected, and tested. Many arrive with low cycle counts and look close to new. Runtime is typically a bit lower than a brand-new pack — the trade-off for a much lower price. Every unit is backed by a warranty by American Oxygen (ask us for the current term).
