Teltonika's IP67 water-resistant 2G tracker with a large 1,800 mAh internal battery · sealed and autonomous for two-wheelers, trailers, and exposed outdoor assets, where the compact FMB920 stays indoors.

Vehicle Types
FMB920 (IP41) is the compact under-dash car install with a small backup cell. FMB204 (IP67) is the sealed, big-battery unit for two-wheelers, trailers, and exposed assets that run for stretches without wired power. Same Teltonika protocol, different housing and battery.
Its 1,800 mAh Li-ion is sized for prolonged autonomous use: at a slow reporting interval it lasts days between charges, which is the point on a trailer or parked asset with no permanent power. Frequent live tracking drains it faster.
It reached end-of-life at Teltonika, so new stock is thinning. It stays a fine choice where you already own units or can source them, and Traxelio decodes it exactly like the rest of the FMB line. For a fresh fleet rollout, pick a current FMB or FMC model instead.
Yes for exposed installs: the IP67 case shrugs off dust and rain, and 2G covers it across Senegal. It uses internal antennas, so mount it with a clear view of the sky rather than inside a metal box, and it holds a GNSS fix.
Overview
Teltonika FMB204 is an IP67 water-resistant 2G GPS tracker with a large 1,800 mAh internal battery, built for prolonged autonomous tracking of two-wheelers, trailers, and exposed outdoor assets. It reports over the Teltonika protocol that Traxelio decodes directly. A mature, end-of-life device still worth running where a sealed, long-battery-life tracker is the point.

IP67 is rated at install time · gaskets and glands age under UV and salt air. Inspect the seal yearly and re-seal with marine-grade silicone if it cracks, especially on coastal mounts.
The FMB204 relies on internal high-gain antennas, so a metal box blocks them. Mount it with the labelled face toward open sky, or move it out of the enclosure entirely · there is no external antenna socket to fall back on.
