Main Page > Professional Trackers > FMB641 > FMB641 Manual > FMB641 General description
Teltonika FMB641 is an updated version of the current most popular GNSS, GSM terminal for
PROFESSIONAL applications FMB640. Compared to FMB640 – FMB641 has a new processor that
improves the device's computation power therefore it can be tailored to more specific use cases.
Switchable CAN terminators that will allow you to use the device in a CAN network with numerous
nodes. Lastly, it can be powered via USB for an easier configuration process. All the features that
are supported by FMB640 are also supported by FMB641, for the purpose of maximizing your fleet
efficiency with features like FMS CAN data (J1939), fuel CAN data (J1708), tachograph live data (K-
Line), remote tachograph file download, various third party RS232 or RS485 devices support and
Dual-SIM or eSIM compatibility. The terminal is suitable for applications like international logistics,
refrigerated transport, agriculture, construction & mining, security & emergency services, and even
more.

CAUTION: RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
Battery should not be disposed of into general household waste.
Bring damaged or worn-out batteries to your local recycling center or dispose them into a
battery recycle bin commonly found in supermarkets.
Battery tests
The amount of time the device will work from internal battery depends on the battery health, how
often the device saves/sends information to the server, external peripherals connected to the device
and the results may also differ depending on firmware used.
For general comparison purpose, and to see what results can be achieved, you can refer to the
following internal test results in different modes and sending frequencies:
