Teltonika TAT141 — 4G LTE Cat M1 Asset Tracker with 5-Year Battery and Encrypted Bluetooth Backup Tracking

The Teltonika TAT141 is one of the most versatile and long-lasting asset trackers in Teltonika's range — a compact 4G LTE Cat M1 and NB-IoT IP68 device that delivers up to 5 years of battery life when used as a Bluetooth backup tracker, and up to 3 years as a standalone GPS asset tracker.

Equipped with a swappable non-rechargeable battery that can be replaced in the field without returning the device for servicing, the TAT141 is built for long-term, low-maintenance asset monitoring across a wide range of demanding applications.

Its most unique capability is encrypted Bluetooth backup tracking — the TAT141 can be paired with Teltonika wired vehicle trackers to act as a covert secondary backup tracker. If a thief removes or disables the main wired tracker, the TAT141 continues tracking and reporting the vehicle's location independently — providing a level of vehicle security that a single tracker system cannot match. Combined with IP68 waterproofing, movement-based configurable reporting, recovery mode and magnetic mounting, the TAT141 is the definitive backup tracker for leasing, car sharing, rental and construction equipment fleets.

As an official Teltonika distributor in the UK, Tracking Hardware UK ships the TAT141 directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Key Features

• Up to 5 years battery life — swappable non-rechargeable Lithium-Thionyl Chloride battery provides up to 5 years as a Bluetooth backup tracker and up to 3 years as a standalone GPS tracker — replaceable in the field without returning the device

• Encrypted Bluetooth backup tracking — pairs with Teltonika wired vehicle trackers via encrypted Bluetooth packets to act as a covert secondary backup tracker — if the main tracker is removed or compromised by a thief, the TAT141 continues tracking independently

• 4G LTE Cat M1 and NB-IoT with 2G fallback — global IoT network connectivity with broad coverage across the UK and internationally, with automatic 2G fallback ensuring continuous operation

• IP68 waterproof and dustproof — fully sealed enclosure for reliable operation in extreme weather conditions and severe temperature deviations

• Movement-based configurable reporting — reports more frequently when the asset is moving and less frequently when stationary for optimised battery life and data usage

• Scheduled tracking — configurable tracking by specific times and days for tailored monitoring scenarios such as weekend vehicle use prevention

• Recovery mode — activates frequent reporting when theft is detected to provide real-time location updates for rapid recovery

• Accelerometer wake-up — automatically wakes from sleep when movement is detected for intelligent power management

• Bluetooth LE connectivity — connects to Teltonika EYE Sensors for indoor asset tracking where GPS signals are unavailable

• Compact and covert form factor — small size enables discreet installation in vehicles and assets where the tracker should not be visible to potential thieves

• Magnetic mounting — easy tool-free attachment to metal surfaces via magnetic mounting accessory

• Swappable battery — non-rechargeable battery replaceable in the field for extended operational life without returning the device

• 128MB internal flash memory — stores data locally when out of coverage

• OTA updates — remote firmware and configuration management via FOTA Web

TAT141 vs TAT240 — Which Should You Choose?

Both are IP68 asset trackers with Bluetooth LE, movement-based reporting and magnetic mounting. The TAT141 uses LTE Cat M1 for broader global IoT coverage and offers up to 5 years battery life with a swappable battery — making it the better choice for long-term standalone deployments and backup vehicle tracking via encrypted Bluetooth. The TAT240 uses LTE Cat 1 for faster data speeds and adds magnetic tamper detection for immediate removal alerts — making it the better choice for rental equipment and assets where tamper alerts are the priority.

Frequently Asked Questions

What is encrypted Bluetooth backup tracking?

The TAT141 pairs with compatible Teltonika wired vehicle trackers via encrypted Bluetooth communication. It periodically scans for the main tracker's encrypted Bluetooth signal. If the main tracker is removed or compromised — a common theft technique — the TAT141 detects its absence and activates as the primary tracker, continuing to report the vehicle's location to the fleet management platform independently.

How long does the TAT141 battery last?

The TAT141 provides up to 5 years of battery life when operating purely as a Bluetooth backup tracker, and up to 3 years as a standalone GPS asset tracker. Actual battery life depends on reporting frequency, temperature, network conditions and enabled features. The battery is swappable in the field for extended operational life.

What is the difference between the TAT141 and the TAT240?

The TAT141 uses LTE Cat M1 with up to 5 years swappable battery and encrypted Bluetooth backup tracking. The TAT240 uses LTE Cat 1 with tamper detection for immediate removal alerts. Choose the TAT141 for long-term backup tracking. Choose the TAT240 when tamper detection is the priority.
