About Cool-Lux SL3000

• When Nickel Cadmium cells are manufactured, they go through several stages - assembly, testing and serializing. After the final manufacturing stage, cells average 1.2 volts each; some higher, some lower. It takes ten cells to make a 12-volt belt. If a lower voltage cell is assembled with a group of stronger or even average cells, the weaker cell is, naturally, going to get charged and discharged first, and eventually it will be the first one to die, killing the entire ten-cell group. To prevent this from happening, a manufacturer must volt-match the cells. This is known in the industry as cell-balancing. This practice allows all cells to charge/discharge at the same time, preventing premature death. Cell-balancing requires special equipment, know-how and time. It is an expensive Quality Check, and the only element aside from the charger that will assure the longevity of your battery. The performance difference between the balance groups is negligible, but extremely important in order to assure top performance and full life cycles.
