Before use, open the case and fit three 1.5 V lithium AA batteries (lithium iron disulphide, such as Energizer Ultimate Lithium; never 3.6 V lithium, alkaline or rechargeable cells), then reseal it: seal clean and lying flat, six screws tightened evenly.

CT-A08 is a rugged 4G GPS asset tracker that runs on three AA lithium batteries, with no wiring and nothing to charge. Batteries are optional: add three Energizer Ultimate Lithium AA cells for $12 and we fit them before it ships, or order it without and fit your own. Without them it ships sealed, with no batteries inside (and our SIM fitted if you choose a data plan): open the case, fit three cells and reseal it before use. Screw it, bolt it or cable-tie it to a trailer, a piece of plant, a shipping container, a generator, a bin, a caravan or a boat trailer and leave it there.
It sleeps when parked, so the batteries go a long way: up to 8 years at one location update a day on Energizer Ultimate Lithium batteries.
When the batteries run low, or if you order it without them, you fit them yourself: no charging and no sending it back to us. Use three 1.5 V lithium AA batteries (lithium iron disulphide, such as Energizer Ultimate Lithium); never 3.6 V lithium, alkaline or rechargeable cells. Fit all three at once, new and from the same pack, never mixed with old cells or another brand. Then reseal the case: check the seal is clean and lying flat, and tighten the six screws evenly.
The sealed, rugged housing is IP68-rated when sealed correctly (dust-tight and protected against immersion) and impact-rated to IK07, and the tracker works from –30 °C to 60 °C. GPS, GLONASS, Galileo and BeiDou give positions accurate to about 2 m, with a rough location from the mobile network when it can’t see the sky. A motion sensor detects when the asset moves, and positions recorded out of coverage are sent once it’s back in range. It measures 108 × 86 × 30 mm and weighs 170 g with its batteries.
Every Crucial Tracking data plan ships with a SIM that works across both the Telstra and Optus mobile networks.
