 Do you have a multimeter or some other type of volt meter that you can check the cell with?  Or a known good cell to see what the charger says about it?  I have several Vapcell that have been very good but it appears some models have had quality problems recently:  last page of thread, some K64 issues  https://budgetlightforum.com/node/63450?page=18

If the charger stopped charging at 1.53V, the better question is where did it start? How did the cell get to this voltage? My understanding is that generally, cells that have been well below 2V are suspect. I have, however, brought some back with my charger(different brand) by waiting until the charger stops charging, then restarting the charger. Many people would say to just recycle the cell because you don’t know what could happen. I would not leave the cell unattended while reviving it from such a state, and it’s quite possible that it would never be “safe” again. They can leak and do bad things. I have some cells that I brought back and one of them looks kinda funky under the wrap. It’s probably time I opened that to see what exactly is going on under the wrap. I’ll update in a few.

Test cell voltage with Multimeter. ‘If’ it’s 1.5v the charger likely doesn’t recognise it to be a li-ion cell, I think they use voltage to varify cell type. The K64 is know to have self discharge issues, if purchased from AliExpress you should get a refund.

I probably should drain and recycle this puppy. Buuuuut, I’ll probably do aggressive capacity tests on it. In a safe manner, of course. Of course.

The charger also has a repair function, maybe that can help? The charger indeed gets the battery type by the voltage the inserted battery has:

The cell probably was very low and the charger thought it was NiMh so stopped charging at 1.5V.
