🔋 How Long Can a 4G Data Logger Last on a Single Charge?

This is one of the most common questions customers ask when choosing a 4G data logger.

After all, everyone wants reliable data logging and automatic cloud uploads without worrying about frequent battery changes or recharging.

So, how does our T671 perform? Let's look at the test results!

📊 Long Battery Life, Proven by Testing
✅ Up to 310 Days of Battery Life

At 2°C, with both the logging and upload intervals set to 60 minutes, the T671 can operate for up to 310 days on a full charge.

✅ Reliable Performance with Frequent Data Uploads

Even when recording data and uploading it to the cloud every 5 minutes, the T671 can operate for approximately 30 days on a full charge at 2°C.

🌐 4G Connectivity for Easier Data Management
The T671 automatically uploads data to the cloud via 4G, allowing you to monitor and access your data remotely while reducing manual work.

Actual battery life depends on ambient temperature, logging intervals, upload frequency, and operating conditions. Choosing the right settings helps balance monitoring needs and battery life.

Today’s factory vlog is here!

A little look into the daily routine at our factory, featuring the Ulogm2s USB reusable data logger.

Come see what we’ve been up to today! 👀

Tens of thousands of data loggers leave our factory every month.

Then one day, one device has an issue.

Can you tell exactly which unit it is?
When was it programmed?
What parameters were loaded into it?

That’s why programming the device is only part of the process.

Before shipment, every logger is programmed with its required parameters and assigned a unique SN code for traceability.

It takes only a few seconds.

But months later, that small SN code can help us trace the exact device and its production record.

A few seconds today.
A traceable record when you need it.
