Charging of battery
-
Hello,
I cannot charge my Suunto Vertical at all; I connect the cable, but the screen stays off. No charging icon appears. Any help?
-
@Danny can you try perhaps multiple USB ports or outlets to rule out a defective charger?
-
Thanks for your answer. I tried, different ports and even different PC. No results.
-
@Danny If you have a multimeter, you could measure the voltage between the two contacts – around 5V DC – to check if the cable is ok
-
@Danny also try powering down the watch completely. On one occasion about 2 years ago, it fixed the issue for me.

I had a similar problem with my daughter’s Huawei Band. The battery was next to empty, but refused to start charging. One internet trick was to put the device in the freezer for 30 mins. That shock treatment did something and it miraculously started charging again.

Just be careful and do not charge while the battery temperature is below 0°C (32°F).
From https://www.batteryuniversity.com/article/bu-410-charging-at-high-and-low-temperatures/
Many battery users are unaware that consumer-grade lithium-ion batteries cannot be charged below 0°C (32°F). Although the pack appears to be charging normally, plating of metallic lithium occurs on the anode during a sub-freezing charge that leads to a permanent degradation in performance and safety.
