How to find a serial number of a tool
Rating Plate: Look at the metal or sticker rating plate located directly on the tool housing.
Handle or Bottom: On specific tools like direct fastening systems (e.g., DX line), the serial number is often stamped or printed on the handle or the bottom base.
NFC Tag: Most modern Hilti tools feature an NFC tag located just underneath or near the rating plate.

How to find a serial number of a battery or charger
Location may differ but serial number will almost always be printed directly on the rating plate itself.
For Batteries: Flip the battery over. The rating plate is usually located on the underside or side casing of the battery. The serial number will be printed near the model name (e.g. B 22-55).
For Chargers: Flip the charger completely over. The rating plate is usually affixed to the bottom base of the unit.
