gifted a friend one for Xmas two years ago and he loves it. uses it around the house and when out RV’ing so lite use. got it out this spring and it was dead! original nitecore battery with a full charge, tried new samsung unprotected button top as well, no go. when trying the built-in usb charger, no joy, no lights. nitecore is will to fix for free if he sends it to china. any suggestions? i hesitate to pull off the cover to get at the circuit board beneath for fear of voiding the warranty. TIA

btw: my daughter is a triple crowner solo “thru hiker” to the tune of ~8,000 miles and she loves the one i gave her and it still works great after over 3,200 miles of trail use.
If the the battery rattles inside the springs might have compressed and lost contact with the battery. Pulling the springs would solve this. Otherwise its actually fairly easy to open the front side. Review: Nitecore HC60
Just take out the four screws and remove cover. Hopefully, its just the wires diaconnected then its an easy fix. The USB charging board on the battery + side can also be taken out after you’ve desoldered the wires, you can check that too.
I had a HC70 that I sent back to nitecore because the battery pack stopped working and they did replace it. It took a few months before I got it back though.
