1. Lithium batteries are regulated dangerous goods
requiring special logistics. Shipping is available to the US, Canada, Australia
and most European countries only. For buyers from other countries, please
inquire before placing an order.
2. For certain countries, buyers are
required to handle customs clearance at the airport or port by themselves.
Please ensure you are capable of doing so, and if you have any queries, feel
free to contact me before making the purchase.
3. For batteries purchased in
bulk, I ensure the time interval between the production date and the shipping
date is no more than 180 days; for non-bulk battery purchases, the interval is
capped at 360 days – this is, of course, the worst-case
scenario.
Action for 130pcs battery, One full case
Battery products are special and do not accept returns. Please
ensure that the product is what you want before purchasing. Thank you for your
understanding
Kindly enquire about stock availability
before placing your order. We appreciate your understanding.
