Battery repair soft-tools are just fake or legend for laptops, because most of batteries are using LI-ON technology
so when battery has been badly used (for example still in the machine while running 100% of time on sector for about a year), the battery is chemically modified inside of itself. so it can never be repaired, you can get a few more battery time for example a battery that take charge of 50% its nominal capacity, will go up back to 60 or 75% for a short period of time (few month) (software tools will show 100% but reality will be 60 to 75%). but then will decrease it capacity very fast , faster by far, than if you didn't try to force its repair... & this is worst again, for older batteries technologies. hardware tools exist that can do the job with better results but they are not cheap. > ---------------------------------------- > From: Alan Corey <alan01...@gmail.com> > Sent: Sun Apr 28 07:16:46 CEST 2013 > To: <misc@openbsd.org> > Subject: open source laptop battery repair? > > > Just wondering if anyone knows about tools for laptop battery repair > that might run under OpenBSD.
