If a battery is matched it will last longer if treated well and gives better performance bacause every cell in the pack is giving close to the same amount of power.

To put it in a nut shell... matched cells are exactly what the name implies... they are "matched" together or "grouped" together along several parameters such as voltage, run-time and IR

They are better in the sense that all six cells will perform almost "simultaneously" giving off "power" at the same rate and at the same time... no one cell will be dead before the others.

hope this helps.

One way to look at it is like a chain. A chain's only as strong as it's weakest link, a battery pack is only as strong as it's weekest cell. If you have one bad cell, you'll get short run times and feel short on power. It'll feel like you're running on a 5 cell instead of 6.

Well spoken ! In addition, that "bad" cell (it might just be sligthly) will be stressed, since it'll be empty before the others. So it will be overdischarged. Even thogh cells are pretty tough, it will die before the others.
