Abstract
A reliable battery module that is safe is of critical importance to battery operated medical devices. This invention limits the amount of active materials in each cell of a battery module. Limiting the amount of active materials in each cell increases the safety and reliability of the battery module by minimizing the effect of a damaged or defective cell on the battery module output and on the potential hazard that such a cell can cause.
