    charging Li Ion Batteries via USB on MoBo/Laptop

    Hi guys.
    I got myself so obsessed with fast charging reading that in long term it can a lot shorten battery life/capacity.
    So I thought why not to charge via USB headers on MoBo or laptop.
    Yeah it's painful slow,but in order to preserve battery capacity/health in long term is that a better solution?
    After all it charges with less current (1-2 Amps).
    I noticed when using genuine charger with my S5e battery now lasts me shorter then before,and I did only 18 charge cycles.
    I used fast charging all the time,but I have a bad habit when not using tablet I swtiched it off most of the time it's off,and maybe those devices like more when they are ON then OFF for the health of the battery?
    Maybe there is an issue.
    I have OCD so I overthink this too much,sorry.
    Can anyone explain me if I'm correct or wrong?

    Over charging batteries depends on the charger as long as the batteries do not because warm it should not be an issue however wherever the batteries are made is a very big issue

    Chinese made batteries are hit and miss in quality (more often they are a miss )
    Korean made are also hit and miss in quality ( about 50/50 is a miss )
    Japan made batteries are the best as in quality ( most of the time you get what you pay for )

    These are solely my options and are to be taken as such

      Cyberpower cps1500avr not charging batteries
      by carrzkiss
      Hello, all.

      Cyberpower Battery Backup Unit.

      I bought two new ML18-12 batteries through Amazon (They have already refunded my money for the two batteries as we thought the batteries might have been bad.)
      When I got them in, they were not fully charged. I connected them to the UPS and waited 24 hours before connecting any networking equipment.
      In parallel, they read 24v, but within 24 hours, the meter on the front of the unit dropped from 4 to 3 bars on the battery charge indicator.
      Checking the voltage, it was down to 22v.
      I quickly removed everything...

      HP Probook 470 G4 - Power and Charging Problem
      by Scoff
      Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
      Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...

      Bosch 12V and 18V chargers modification
      by Petr0x
      Hi, I would like to share with you small modification to your Bosch tool 12V and 18V chargers.

      You can use it for almost all Bosch chargers what I have seen, for example part numbers GAL 18V-20, GAL 18V-40, GAL 1880, GAL 18V-160, AL 1820, AL1115CV, AL1130CV.

      Bosch (today also other brands using the same system like Wurth, Fein) does not care if you destroy your batteries, because they can sell you new ones. So the marketing is telling you only about speed of the charging, so you will not wait for your batteries to charge too long. Me as a customer want the tools and batteries...

      Acer Nitro 5 AN515-45 not charging
      by CPUFiddler
      Hi there. I am trying to repair an Acer Nitro 5 AN515-45 and it's giving me some trouble. I have access to SMD rework station, variable power supply, digital oscilloscope, thermal camera, multimeter, stereo microscope.
      This laptop will boot and run from the power brick and/or the internal battery, but it will not charge the battery. NirSoft BattInfo tells me the charge/discharge currents, so I'm confident in saying that it's not charging. In addition, there's no increase in voltage at the battery connector when the laptop thinks it's charging, not even a few millivolts.
      I've downloaded...

      Cyberpower 1500AVR UPS repair
      by quickname
      I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.

      Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.

      I decided to verify that the batteries were...
