International Orders

International shipping fees charged by Stainout System do not include customs duties, import taxes, or additional fees required by the destination country. These charges are set and collected by local authorities, and Stainout System cannot estimate or waive them. We encourage international customers to check with their local customs office prior to placing an order.

If an international shipment is declined due to unpaid customs fees, duties, or taxes, Stainout System will refund the purchase price less original shipping costs and a 20% restocking fee.

Avoid deep discharges (Dont let them run completely dead)

Avoid overcharging- Unplug the battery once charging is complete.

Store in cool dry places

Let hot batteries cool before recharging to extend their life and performance

If possible rotate batteries. If you have several, use them in rotation for even wear
