What this means is that the maximum voltage of the cell is 4.2v and that the "nominal" (average) voltage is 3.7V.As the battery is used, the …

laptop

It''s usually 11.1v or 14.8v, a multiple of 3.7v which is the nominal voltage of a LiCoO2 cell (the most common chemistry used in laptop battery packs). For your 4-cell pack the 2620mAh is the rating of each cell, but if they made an 11.1v 6-cell or 14.8 8-cell version with the same cells those would be rated 5240mAh (2x as the additional ...

BU-303: Confusion with Voltages

Lead Acid. The nominal voltage of lead acid is 2 volts per cell, however when measuring the open circuit voltage, the OCV of a charged and rested battery should be 2.1V/cell. Keeping lead acid much below 2.1V/cell will cause the buildup of sulfation. While on float charge, lead acid measures about 2.25V/cell, higher during normal charge.

Why is a laptop power supply output voltage different from its …

The voltage on your battery "10.8V" is the "nameplate" voltage, some average voltage that your battery delivers over full discharge cycle. The value of "10.8" indicates that this is a battery of 3 Li-Ion cells in series, giving their standard "nameplate" voltage of 3.6V per cell.
