Teltonika TAT100 Review: Battery Asset Tracker for Fleets

The Teltonika TAT100 is a battery-powered asset tracker for fleets that need visibility without hardwiring. This review covers use cases, limitations, alerts and when another tracker may be a better fit.

Not every asset you need to track has a 12V power supply. Trailers, portable equipment, motorcycles, containers, and non-motorised vehicles all need a tracker that runs on its own battery. The Teltonika TAT100 was built exactly for this purpose — a compact, self-powered GPS device that tracks anything, anywhere, without needing a wiring connection.

What Is the Teltonika TAT100?

The TAT100 is a compact battery-powered GPS tracker from Teltonika. It runs entirely from a non-rechargeable 2200 mAh Li-SOCl2 battery pack, which is replaced in the field rather than recharged, with no need for hardwired power, making it ideal for tracking assets that aren't always connected to a vehicle's supply. It communicates over 2G cellular networks and uses GNSS for precise positioning, with an accelerometer onboard that detects movement.

TAT100 Battery Life and Reporting

In standard tracking mode the TAT100 sends position updates at configurable intervals. Extended battery life modes allow the device to sleep between reports, dramatically extending runtime — ideal for trailers or equipment that don't move daily. In slow reporting deployments a single set of cells gives a long service life, and at the end of it the cells are swapped rather than recharged. When assets start moving, the accelerometer wakes the device and triggers more frequent position updates automatically, so you always know when something has moved.

What Can You Track with the TAT100?

The TAT100 suits any asset without a dedicated 12V supply: unaccompanied trailers in a yard or parked between drops, portable tools, generators, and plant equipment on construction sites, motorcycles and bicycles where hardwiring isn't practical, shipping containers and cargo pallets in transit, and storage units or site equipment that need low-frequency check-in tracking. If the asset has value and moves — or shouldn't move — the TAT100 provides a cost-effective solution.

TAT100 vs Hardwired GPS Tracker

The TAT100 is the right choice when an asset has no constant power supply, when you need quick deployment without professional installation, or when the asset moves infrequently. For vehicles with a 12V supply — vans, trucks, cars — a hardwired Teltonika device like the Teltonika FMB920 or FMC920 provides richer data and more features including driver identification keypads integration over Bluetooth LE. For CAN bus vehicle data you would step up to a CAN-capable model such as the FMB140, which reads CAN natively, or the FMC130 with a Teltonika CAN adapter.

Useful next steps for choosing hardware

For battery-powered asset deployments, compare the Teltonika TAT100 asset tracker with the wider Teltonika 4G tracker guide so powered and self-powered assets sit in one hardware plan.

For trailers, plant, containers or African field operations, the Africa fleet tracking guide explains where battery life, roaming and recovery workflows matter most.

TAT240 option for tamper-sensitive assets

If the asset needs stronger tamper awareness, compare the Teltonika TAT240 LTE Cat 1 tamper asset tracker with the TAT100 before specifying hardware. TAT240 is the better shortlist item where magnetic mounting, IP68 housing, GNSS, Bluetooth LE and movement/tamper reporting matter more than the lowest-cost battery tracker.

Where TAT100 Fits in the Asset Tracking Range

The Teltonika TAT100 is useful for simple battery-powered asset tracking, while the Teltonika TAT240 is the stronger choice where ruggedness, newer hardware or more demanding asset projects matter.

For mixed fleets, combine battery asset trackers with powered Teltonika GPS trackers, Queclink rugged asset trackers and Driver Identification where vehicles or equipment are shared between operators.

FAQ

Is TAT100 still a good asset tracker?

Yes, for straightforward battery-powered asset tracking where the reporting schedule, installation environment and battery expectations match the device.

When should fleets choose TAT240 instead of TAT100?

Choose TAT240 when the project needs a newer rugged asset tracker for harsher conditions, higher-value equipment or longer-term fleet standardisation.
