This article explains how to charge a flex tracker.
Flex Tracker charging guide
- Flex TT600 does not have a port for external communication/charging so it can only be charged by placing it directly under the sun.
- Flex TT603 can be charged using the M8 cable that needs to be purchased separately.
- The device can be plugged into most bench-top supplies/wall adapters rated at 12V.
Additional notes
TT60x needs 6-12 days (40-80 hours at 7 hours per day) of full sunlight to go from 0% to 100% battery charge. The device battery level needs to be at least 20% to get a once-daily report, and at least 30% to get 4 minute GPS collection when moving, which can take 2-5 days of full sun exposure to reach.
If conditions are overcast or partly cloudy, charge rate can reduce to only 5% to 20% of full sunlight which means it could take over 40 days at worst case overcast for the device to reach 30% charge from 0%.
If the device is kept in the sun but behind the window, it may not charge through the window as some windows filter usable sunlight, and since the device is fully drained it will take a while for the batteries to charge. For best results, devices should be in the open air and not behind the window.
Do not place the device in direct sunlight in an enclosed space such on the dashboard of an unattended vehicle. Not only will the device not be able to charge in high heat, temperatures in such spaces will exceed the operating range of the device and will shorten the device battery life."
