| Aug 22, 2022 at 16:23 | comment | added | NeStack | thanks a lot! I can tell the following: 1) I definitely smelled something when I went into the garage after 90 min charging, but I am not sure it was sulfur. I thought it might be ozone, which I considered normal for charging devices. 2) I measured the voltage of the battery and it showed surprisingly 11V after 90 min charging! 3) Is it possible to open all car batteries? I think mine is not manufactured that way. I would appreciate if you have further comments, especially on 2). | |
