If the cells are very different in State of Charge (SoC) when assembled the Battery Management System (BMS) will have to gross balance the cells on the first charge. This can take a long time as the maintenance balancing currents are generally very small compared to the Ah ratings of the cells (1 to 3mA/Ah).
A manufacturer cannot predict the exact capacity when the cell comes off the production line, and this is especially true with lead acid and other batteries that involve manual assembly. Even fully automated cell production in clean rooms causes performance differences.
Cell matching according to capacity is important, especially for industrial batteries, and no perfect match is possible. If slightly off, nickel-based cells adapt to each other after a few charge/discharge cycles similar to the players on a winning sports team.
Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. If the cells are very different in State of Charge (SoC) when assembled the Battery Management System (BMS) will have to gross balance the cells on the first charge.
When cycled, all batteries show large capacity losses over 18 cycles, but the greatest decrease occurs with the pack exhibiting 12 percent capacity mismatch. Battery packs with well-matched cells perform better than those in which the cell or group of cells differ in serial connection.
