Because mailing increases transportation costs, it is much more expensive than before. We adjust the shipping method based on the quantity purchased: If you buy 1 battery, we will send it through long haul, no tracking information, delivery time is about 60-80 working days. For purchases of 2 or more, we will use the fast shipping channel to send and provide tracking information. The delivery time is about 30-60 working days. Please note this before placing an order, we recommend that you purchase more than two quantities so that you will receive the package faster
