      It could be that your meter is off a little bit or the switching power supply is set up that way or if it is a linear power supply which in general they are not regulated very well sometimes

      it would help if you posted a picture of the power supply in question so we can give you a better idea and answer to your question

          ISL88739AHRZ ISL88739 Laptop Battery Charger Datasheet
          by Document Archive
          The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
          configurable for operating as either a Hybrid Power Boost (HPB)
          charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
          4-cell batteries. Both configurations allow the battery to work with
          the adapter together to supply the system load when it exceeds
          the adapter capability, referred to as system Turbo mode. HPB
          charger configuration reverse-boosts battery energy to the system
          bus to help the adapter provide the system power in Turbo mode.
          NVDC charger configuration...

          Highly Integrated Narrow VDC Battery Charger for Notebook Computers

          The ISL6257HRZ ISL6257HRZ-T is a highly integrated battery charger controller
          for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for
          Narrow VDC applications where the system power source is
          either the battery pack or the regulated output of the charger.
          This makes the max voltage to the system equal to the max
          battery voltage instead of the max adapter voltage. Operating
          at lower system voltage can improve...

          Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
          by Bowline
          My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

          Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

          My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
          The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
          I have tried multiple different Dell power adapters. My Dell...

          Bauer tool battery pack charging with a HERCULES charger modification
          by sam_sam_sam
          The Bauer power tool battery charger just has to many issues with the charger over heating because I several HERCULES Hercules battery chargers that are 3 amp charge and because they have gone on quite a few times over the years before they came out with the fan cooling battery charger I going to modify one so I can charge Bauer battery packs faster than the crape battery charger that they have

          Here is how this modification is going to be done I taking a 1.5 amp hour battery enclosure and gutting it removing the battery cells and replacing some Ryobi 1.5 amp hour battery pack that...

          Milwaukee M18 HD12.0 (12 amp hour battery pack) unbalanced failure charger refusing
          by sam_sam_sam
          I have two Milwaukee 12 amp hours battery packs that have an issue with battery cells very unbalanced these are probably over 4 years old and been heavily used in the past but now get occasionally used heavily and when I went to use the grinder tool the battery lost battery battery power very quickly so I decided to open it up and found some battery cells voltage from 3.6 to 4.1 no wonder the battery charger was not fully charging them 3 out of 4 LEDs were on meaning that it was only 75% charged

          So I have put them on the battery testing machine to drain each battery cell down to...
