Frequently Asked Questions
How long does the GL521MG battery last?
The manufacturer specifies up to 1 year at one daily report under long-standby conditions. Reporting frequency, movement, signal, temperature and accessories affect the interval between charges.
How is GL521MG recharged?
It supports Qi wireless charging. Confirm the approved compatible charger and power supply, whether the kit is included, and the manufacturer’s charging procedure.
What is different about GL520MG and GL521MG batteries?
GL521MG has a rechargeable 2,400mAh Li-Polymer battery. GL520MG uses a replaceable CR123A pack, with separate GNSS and Cell ID standby estimates. Choose against your maintenance and reporting plan.
Will every BLE sensor or keypad work with GL521MG?
No. BLE 5.2 alone does not establish compatibility. Check the exact accessory, firmware, data protocol and receiving-platform workflow before ordering.
Can the internal sensor measure cargo temperature?
It monitors temperature within the device. Check placement, accuracy, calibration and the required monitoring workflow; an internal measurement may differ from the temperature of the goods.
