As per the UN international shipping regulations for Lithium batteries, they have a (peel off) label with the nominal capacity, nominal voltage and size.

These are high capacity and high discharge current batteries. If mishandled / mistreated, they can cause you SERIOUS INJURY. USE AT YOUR OWN RISK !

Safety Notes:

Do NOT short.
Do NOT leave unattended when charging.
Do NOT leave unattended immediately AFTER charging.
Do NOT carry in your pocket or purse unless they are in a secure non-conductive carry case.

Stickers on your battery?

Note that many lithium-ion batteries have a separate sticker on each cell which states the cell’s size, voltage, and capacity. International shipping rules mandated by the United Nations require this information for each cell when shipped via air freight (note: this is not necessary for sea shipping.) Suppliers will print batteries or tape a piece of paper with this information and stick it to the battery. It does not mean the batteries are fake, just that they were shipped via air freight from Asia and the suppliers needed a simple way to comply with the rules.
