What is a battery-powered tracker?
A battery-powered tracker is a self-contained GPS device that runs on internal lithium cells rather than your vehicle’s electrics. It periodically wakes, acquires a position, sends the location to the app, then goes back to sleep to conserve power. Because there is no wiring, it is ideal for assets that do not have an electrical system, for example, trailers, horseboxes, generators, plant, or agricultural equipment. Many owners also use a wireless tracker as a covert backup to a primary hardwired unit on a car or motorhome. This kind of hidden, DIY wireless tracker can act as an extra layer of protection if a thief locates the main unit.

Battery-powered vs hardwired: which should you pick?
Choose a battery-powered tracker if you want:
Tracking for an asset with no permanent power, for example, a trailer or horsebox
A covert back-up device that is difficult to locate, since it sleeps most of the time
Quick DIY installation, flexible placement, and low running costs
This setup suits anyone who wants a small, waterproof IP67 tracker that can be moved between assets, for example a horsebox tracker during show season or a trailer tracker when moving kit.
Choose a hardwired tracker if you need:
Live, real-time tracking on demand with continuous power
Insurance alignment through a Thatcham S7 or S5 system with 24,7 monitoring
Driver recognition or features your insurer specifically requires
Relevant options:
Self-monitored live tracking, Meta Trak Shield
Insurance-approved tracking, Meta Trak S7 and Meta Trak S5
Caravan security with towing recognition and a secondary wireless back-up, Meta Trak S7 Caravan PRO
Who should consider a wireless battery tracker?
Caravan owners, as a simple covert back-up to an insurance-approved system. For a complete package with towing recognition and a bundled wireless device, see Meta Trak S7 Caravan PRO.
Trailer and horsebox owners, where wiring is impractical. See our Trailer Tracker page. A wireless battery tracker for trailer security is ideal when you cannot hardwire.
Plant, agricultural, and light construction users, who need a discreet, weatherproof tracker that does not touch the asset’s electrics. A covert tracker for plant and machinery that is self-powered is harder to find and keeps running during storage.
High-value vehicles that already run a hardwired tracker, where a wireless unit adds redundancy. Many owners add a small tracker for vehicle peace of mind, especially if the vehicle is stored off site.

How battery life really works on a wireless tracker
Battery life depends on three main variables:
Wake-up frequency
Every wake-up consumes power. Fewer daily updates equal longer life. Many owners target 12 to 18 months between battery changes when using several updates per day. If you only need infrequent checks, you can stretch service life much further. For example, a battery GPS tracker with geo-fence and theft mode might be set to a few check-ins per day during storage, then switched to faster updates when an alert fires.
Environment and signal conditions
Poor GPS or mobile signal can make a device work harder to get a fix or transmit data, which uses more power. Mount the tracker in a location that balances concealment with the ability to “see” the sky. Metal enclosures or dense material can reduce performance, so choose the hiding place carefully.
Incidents and forced updates
If you enable Theft Mode for fast, repeated updates, batteries will drain more quickly. It is a smart trade in a theft scenario, but remember to disable Theft Mode or set a time limit after recovery. Thieves often move assets quickly, so short, rapid bursts of reporting are usually enough for recovery teams.
Battery type and replacement
Pulsar uses Panasonic CR123A 3 V Lithium cells in matched pairs. Always replace with matched industrial cells to maintain performance. Keep a spare set of CR123A tracker batteries on hand if you choose a more frequent schedule.
Key features explained
Scheduled tracking with on-demand requests
The device sleeps and wakes on your chosen schedule to check for new commands and report its position. You can queue a one-off position request in the app, which runs at the next wake-up. This preserves battery life while keeping you in control. It is ideal when you need a quick location check on a battery-powered tracker for car or trailer without switching to constant live tracking.
Theft Mode for rapid recovery
If you confirm suspicious movement or a theft, switch on Theft Mode in the app. The tracker then reports at high frequency for detailed movement history and a stronger chance of recovery. Set a time limit so you do not forget to turn it off.
Geo-Fence alerts
Create a Geo-Fence around your storage location. If the asset leaves that area, you receive an alert at the next update or when you request a position. You can also choose to trigger Theft Mode automatically when a boundary is breached. This is particularly useful for a wireless battery tracker for trailer security, where movement outside set hours is uncommon.
Waterproof, compact, and discreet
Pulsar’s IP67 rating and small footprint make it easy to conceal. You can mount with automotive adhesive pads or a magnetic plate, depending on surface and placement. If you need a waterproof IP67 tracker for exposed locations, Pulsar’s casing is built for it.
Installation, activation, and lead times
DIY install is straightforward, normally about 10 minutes once you know your hiding spot. The activation process is guided, and app access is provided after purchase or installation. Prefer a hands-off setup, choose professional installation at checkout. Typical lead times for installs are about 2 to 5 days, depending on location and diary availability. If you are looking for a self install tracker that is genuinely simple, Pulsar’s workflow is designed for DIY wireless tracker users.

Is a battery tracker insurance-approved?
Self-monitored wireless devices are not Thatcham-approved. If your insurer requires certification and 24,7 monitoring, choose a Thatcham S7 or Thatcham S5 system:
Meta Trak S7, Thatcham S7 tracking with monitoring
Meta Trak S5, adds driver recognition and higher-tier compliance
Meta Trak S7 Caravan PRO, caravan-specific features including towing recognition and a bundled wireless back-up device
If you want real-time tracking without monitored certification, consider Meta Trak Shield as a self-monitored hardwired option.
Recommended update schedules
Your update schedule should match asset value, risk and how quickly you need information.
Low-risk storage, for example, a garden trailer on private property, set one or two updates per day and rely on Theft Mode if something happens
Mixed risk or frequent movement, set three to six updates per day for a good balance of history and battery life
High-risk assets, consider 12 to 24 updates per day for closer visibility, and plan proactive battery changes so you always have healthy reserves
Tip: Avoid running the most aggressive schedule every day. Keep some headroom for Theft Mode during rare incidents. Owners who need a dedicated horsebox tracker or trailer tracker often pick a mid-range schedule, then tighten it when travelling.
Common use cases and practical setups
Trailers and horseboxes
Primary tracking where wiring is not feasible
Hide the unit in a non-obvious location such as a protected cavity or structural box section
Pair with a visible deterrent, and protect the towing vehicle with a Thatcham S7 or S5 tracker if it is high value See Trailer Tracker for options.
Caravans
For insurer alignment, start with Meta Trak S7 Caravan PRO, which includes a secondary wireless device
If you already have a Thatcham system, adding a wireless back-up boosts resilience
Cars, vans, and motorhomes
If you want live tracking, choose Meta Trak Shield or an S7, S5 system if required by your insurer
Add a battery tracker as a covert secondary, useful if thieves attempt to locate the hardwired unit
When you want more than tracking, add immobilisation
Tracking helps with recovery after the fact. Immobilisation helps prevent movement in the first place. Consider pairing your tracker with an engine immobiliser such as Meta AUTOBLOK. For a layered approach, read our guide to Combined Tracker and Immobiliser Systems and explore Engine Immobilisers.
Frequently asked questions about battery-powered trackers
Can I install a battery-powered tracker myself?
Yes. Wireless units are DIY-friendly and activation is guided. If you prefer, choose professional installation at checkout.

You choose the wake-up schedule in the app, from a few times per week to many times per day. You can also queue a one-off position request, which runs at the device’s next wake-up.
What happens during a theft?
Enable Theft Mode in the app. The device switches to fast updates, roughly every 60 seconds, to help with recovery. Remember to disable Theft Mode after the incident or set a time limit.
How long do the batteries last?
It depends on update frequency, environment, and incident use. Many owners aim for 12 to 18 months between battery changes with multiple daily updates. Always use matched Panasonic CR123A lithium cells.
Is a wireless tracker insurance-approved?
Most self-monitored battery trackers are not Thatcham-approved, although some are. If your insurer requires it, choose Meta Trak S7 or Meta Trak S5.
How quickly can I get set up?
DIY can be about 10 minutes once you have a hiding place. Professional installation is typically about 2 to 5 days, depending on location and scheduling.
Are wireless trackers easy to find?
Because they spend most of their time asleep, they are harder to detect with scanning equipment. Physical discovery is still possible, so choose a well-concealed location.
Can a battery tracker work alongside a hardwired tracker?
Yes. Many owners run a dual-tracker setup, combining a monitored hardwired unit with a covert wireless back-up for resilience.
The bottom line
If you want a simple, low-maintenance way to keep tabs on vehicles and non-powered assets, a battery-powered tracker is an excellent choice. Meta Trak Pulsar offers clear pricing, flexible update schedules, strong geo-fence and theft-recovery features, and a compact waterproof design that is easy to conceal. If you require live tracking or insurance approval, pick a hardwired Thatcham S7 or S5 system instead, and consider adding an immobiliser for stronger prevention.
