I don't have any specific recommendations, but I think if you search the forum for device recommendations with large battery, there were quite a few threads about them.
Hi Arthur, a good device to use is Meitrack TA255.
Link below if you want to have a look.
Hi Arthur,
The Mictrack MT700 is also a low-cost but Super long battery life asset tracking device for containers. In real-time, it can work for 2 weeks, and in deep sleep mode, it can work for 7 years.
Thanks,
Mictrack
Hey,
My father has a renting container business with 45 assets, he has office containers, bathroom, etc... I see mostly of the devices are made for cars, but as we want to track containers, I just need a basic tracker which sends me location and nothing more than that, also I need a device which can hold up to 72h on battery. Does anyone know a low-cost device that I can integrate to Traccar with these requirements?
