IMPORTANT SHIPPING NOTE FOR PADDED MAILING OPTION AND PARCEL FORWARDERS
These batteries do not have plastic anti-shorting rings along the perimeter. The option is available to ship these using low-cost methods, but if the batteries are compressed during shipment they may arrive non-functioning. It's rare but it does happen.
Customers that use parcel forwarders: Forwarding companies will pack as much as possible into a consolidated package. Please let us know in advance if we are delivering to a parcel forwarding service.
Using a non-boxed shipping method or delivering to a forwarder without notification means accepting the risk of non-functioning batteries.
