CCTR-800+ battery level difference between SMS and Traccar

Xander5 years ago

I noticed that the battery level displayed in Traccar is different from the battery level returned by the CCTR-800+ tracking device through SMS. The level stated in the SMS is significly higher than the level in Traccar. For example 79% in traccar vs 99% in the SMS message.

Which would be the most accurate battery level and why would it be different?
