Teltonika FMB204 — Special IP67 Waterproof 2G GPS Tracker with 6-Day Battery Life

The Teltonika FMB204 is one of the most unique devices in Teltonika's tracker range — a special IP67 waterproof 2G tracker built around a large capacity LiPo backup battery that enables the device to operate standalone for up to 6 days in power saving mode without any external power supply. This exceptional battery life makes the FMB204 the definitive choice for trailer tracking, where vehicles regularly detach from their tractor units and need to continue reporting location and status for extended periods without a power connection.

IP67 rated for dust and water resistance, with a wide 6-30V power input range that covers standard 12V cars and motorcycles through to 24V commercial vehicles and marine electrical systems, the FMB204 is one of Teltonika's most versatile waterproof trackers — equally at home on agricultural machinery, refrigerated transport, motorcycles, watercraft and emergency service vehicles. Its Bluetooth 4.0 connectivity supports Teltonika EYE Sensors and EYE Beacons for extended cargo and asset monitoring, and the 1-Wire interface connects temperature sensors for cold chain compliance alongside iButton driver identification.

As an official Teltonika distributor in the UK, Tracking Hardware UK ships the FMB204 directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

FMB204 vs FMB920 — Which Should You Choose?

Both are compact IP67 capable 2G trackers from Teltonika. The FMB920 is a basic compact tracker optimised for covert light vehicle installation with Bluetooth and backup battery. The FMB204 is a special tracker with a significantly larger LiPo battery for up to 6 days standalone operation, wide 6-30V input range covering motorcycles and marine, and Bluetooth sensor support via EYE accessories. Choose the FMB204 when extended standalone battery life, wide voltage compatibility or trailer tracking are the priority.

Frequently Asked Questions

How long does the FMB204 battery last without external power?

The FMB204 can operate for up to 6 days in power saving mode without any external power supply.
