No Air Battery

New Federal lithium-ion battery shipping regulations limit the shipping methods and delivery destination availability for orders containing specific lithium-ion batteries. These items are marked as no air shipping. Due to these restrictions, we can only ship these lithium-ion batteries inside the U.S. (lower 48 states) via ground surface shipping, We currently are using UPS Ground. Which does not have a guaranteed delivery date but is faster than USPS Parcel Select. We can still ship items marked no air shipping via ground surface transportation only to Alaska. But will add substantial time because they can not travel air. We are required to indicate that your package contains a lithium-ion battery for safe transport and handling. This can cause irregular tracking updates and delays while in transit, and this method is not guaranteed to arrive by the estimated date shown during checkout. We apologize for the inconvenience if your order is affected by delays. USPS Priority Mail and some First class Mail is shipped Air. Due to this all battery ground transportation orders only should go UPS Ground as Parcel Select through the post office can add substantial time.
