The present disclosure is directed systems and methods for monitoring battery conditions. In one illustrative embodiment, a system in accordance with the present disclosure may include a number of battery sensor units, each battery sensor unit being in operative communication with sensors on each individual cell on a battery, such as a battery used for supplying power to an industrial vehicle. The battery sensor units may track the supply voltage, temperature, and/or electrolyte level for each cell on a battery. One or more site gateways disposed at the location where the batteries are in use are in operative communication with the battery sensor units and through a network connection provide data collected by the battery sensor units to a database that can be accessed by remote users using an internet accessible portal or mobile app. The system may provide real time alerts for out of bound conditions.
