A battery module includes a housing. The battery module also includes a cell stack disposed in the housing and including a battery cell. The battery module also includes a force gauge in mechanical communication with the cell stack and configured to measure a force generated by a swelling of the cell stack. The battery module also includes a control module configured to receive data indicative of the force and to estimate a remaining usable life of the battery module based on the data.
