How long will the batteries last?

Predicting battery life ahead of time is a difficult task given many different factors including but not limited to:  

  • Average operating temperature 
  • ​GPS and Cellular reception 
  • Device movement patterns 
  • Device settings and configuration  
  • Battery type and quality 

The Oyster2 is highly configurable and has a variety of different tracking modes so that you can choose the optimum balance between getting the information that you need as well as achieving your required battery life.  

In short, you can expect up to 7 years battery life at 1 position per day! 

If set to track based on movement, lifetime will be 6 to 18 months depending on movement and your specific settings.  

Ensuring reliable low battery alerts are sent is extremely important so that they can be changed in time. To provide this the Oyster2 has a Battery Meter (coulomb counter) which tracks the energy used by the device, and given we know the total energy stored in the batteries, we can give a percentage.  

This also means we get real world energy consumption.  

So the task of predicting battery life becomes easy! Run the Oyster2 in your application for a week or two, look at the real-world data drawn from having the device in your application, with your settings – and Telematics Guru will give you an estimated battery life. No more fiddling with spreadsheets and calculations.

Can I change the update rate?

All settings are easily configurable over the air via our device management platform, OEM Server.  

Switch between periodic, GPS movement based, and accelerometer movement-based tracking modes with ease.  

The device cleverly uses the Accelerometer and GPS in tandem to vary the update rate based on movement, giving you more detail where you need it, and preserving battery life where you don’t.  

The device can be set to report infrequently, but then be switched into Recovery Mode (live tracking) over the air – allowing you to recover a missing or stolen asset.

Can I get an alert when the device starts moving or leaves a geofence?

Yes, we have multiple alert options including: 

  • Wake and upload as soon as any minor accelerometer movement (jostling) is detected.
  • Wake and upload after moving a certain distance from stationary, or upon entering or leaving a geofence.

​Geofences can even be downloaded to and stored on the device via Telematics Guru. This allows the device to vary its update rate based on where it is. Perhaps providing extra reporting when in an area of interest.

Can the device track run hours?

The Oyster2 can be set to “Jostle Mode” which means that it will go ‘in trip’ whenever vibration is detected, for example when a pump or generator starts up. This trip time is added to the device’s run hours. Jostle Mode is independent of GPS.

What batteries do I need to use?

The Oyster2 is powered by user replaceable AA batteries – no sending the device back to the supplier for a battery change! 

The Oyster2 supports a wide input voltage range (4-16V) enabling off-the-shelf Lithium Iron Disulphide (LiFeSO2) such as Energizer Ultimate Lithium batteries to be used. The device can also be fitted with Lithium Thionyl Chloride (LTC) batteries if extended temperature tolerance and optimum performance is required.

How do I mount the device? Can I put it under a trailer?

Convenient mounting tabs with screw holes enable the device to be screwed or bolted to an asset. Strap slots are also available for cable ties/straps.  

GPS and Cellular Signals are amplified by Low Noise Amplifiers (LNAs), meaning they can still perform in very harsh signal environments. The Oyster2 has been proven to work on the under side of trailers, hidden under seats, in glove boxes etc.

Can the Oyster2 handle hot temperatures?

Yes! Our new nylon glass (black housing) can reach +85 C / 185 F.

Do I get a warning if the battery is running low?

Yes, the Oyster2 has a default low battery warning alert, which triggers at 15% remaining life by default. Our tracking platform Telematics Guru also displays battery life percentages.
  • Hardware Features

    Low-profile IP67 rugged housing

    The housing screws together for easy assembly, and has 2 convenient mounting tabs. It also has ‘strap slots’ allowing the Oyster2 to be cable tied or metal strapped to an asset. It is low-profile making it easier to mount in the corrugation on containers or concealed on the underside of a trailer, for example.

    Dimensions:L 137 x W 72 x H 30mm


    AA size:
    The Oyster2 uses 3 x “AA” size batteries.

    Off-the-shelf Lithium:
    The device can be fitted with off-the-shelf 1.5V Lithium batteries. These are readily available from retail outlets, for example Energizer Ultimate Lithium.

    Lithium Thionyl Chloride (LTC) Batteries:
    For optimum performance the device can be fitted with LTC Batteries. This kind of battery offers extended temperature tolerance, high capacity and extremely low self-discharge rates.

    Battery Life with Adaptive-Tracking

    The Oyster2 can be set to use Adaptive-Tracking technology where the accelerometer and GPS data are used to intelligently work out if it is moving and to send frequent updates, and to scale the update rate down to once per day if the asset is stationary - to preserve battery life.

    Operating Temperature

    -20°C to +60°C

    For operation in extreme temperatures, the Oyster2 must be fitted with LTC batteries. Batteries are affected by temperature extremes and typical performance is dependent on temperature.

    High sensitivity GPS

    • Supports concurrent GPS and GLONASS
    • 72 channel high sensitivity receiver
    • -167dBm industry leading tracking performance
    • Optimal hot-start performance.
    • AssistNow Offline aiding data for fast time-to-first-fix and performance in urban canyon environments


    The Oyster2 uses both the GPS and GLONASS positioning systems simultaneously. This allows the device to use twice the number of satellites to get a position fix – making it faster and more accurate.

    Low Noise GPS Amplifier (LNA)

    GPS signals are boosted by a special low-noise amplifier (LNA). This allows the Oyster2 to operate where normal units will fail to receive GPS signal – like in a container stack!

    Cellular Communications

    The Oyster2 can be manufactured for specific markets around the world depending on their modem requirements. Available in 2G or 4G

    2G Modem
    2G: SARA-G350-02S-01
    850/900/1800/1900 MHz

    4G Modem
    uBlox SARA-R410M Modem operates on all major global LTE-Cat-M1 and NB-IoT bands. These new low-power networks are specifically designed for IoT applications, providing great battery life

    Supported LTE bands:
    1*, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26*, 28 (*roaming bands)

    Internal Antenna

    Internal GPS and Cellular RF antennas tuned by the RF laboratories to ensure optimal performance.

    3 Axis Accelerometer

    The 3-axis accelerometer allows the Oyster2 to ‘sleep’ in an ultra-low power state yet still wakeup when movement occurs.

    The accelerometer also allows for High G-force event detection (like assets being dropped or involved in accidents)

    Flash Memory

    The Oyster2 has enough flash to store many weeks of data records, and will record information even when out of cellular coverage.

    The flash memory is also used to store firmware updates, GPS aiding data, parameters and other important information.

    Battery Meter

    A coulomb counter acts as a battery meter, tracking the energy consumption of the device. This enables an accurate battery percentage to be reported. The battery meter also allows accurate battery life predictions. Simply deploy the device in your application with the desired settings. The energy usage will be reported, enabling you to extrapolate to determine the battery life time.

  • Firmware Smarts

    OTA Configuration

    The Oyster2 can be remotely configured and updated OTA (over the air). Device management is performed from Digital Matter’s OEM Server device management platform.

    AES-256 Security

    The Oyster2 uses bank-level AES-256 device authentication and data encryption to ensure that your data is kept private and secure.

    Adaptive Tracking

    The Oyster2 can be set to use Adaptive-Tracking technology where the accelerometer and GPS data are used to intelligently work out of the device is moving and to send frequent updates, and to scale the update rate down to once per day if the asset is stationary - to preserve battery life.

    Recovery Mode

    The device can be remotely switched into Recovery Mode which switches the device to into "Live Tracking" mode – so that you can get your asset back!

    Text Message Setup

    The Oyster can also be sent text messages to setup the APN, server and other details.

    AssistNow Offline

    The Oyster2 will track successfully where other devices just give up.

    This fantastic technology allows the GPS to predict which satellites are in orbit above it and to dramatically reduce the time-to-first-fix of the GPS, and the overall performance of the GPS, especially in ‘urban canyon’ or forested environments

    G-Force Events

    The 3-axis accelerometer allows for high G-force events (like assets being dropped or involved in accidents) to be detected and reported to the server.

    After Hours

    The Oyster2 can be set to alert on after hours activity, and use different logging parameters after hours.


    The Oyster2 has the capacity to hold hundreds of geo-fences that can be downloaded to it from the server and updated over-the-air. This information can be used to implement geo-fence based alerting on the device, or to set alternate logging parameters when inside a geo-fence.
