1. A method for monitoring a battery of a vehicle having an internal combustion engine, a starter motor and an alternator, the method comprising:
receiving, at a telematics hardware device located on board the vehicle, a plurality of battery voltages for the battery of the vehicle during an engine starting event that includes a first time period during which the battery provides electrical energy to the starter motor to start the internal combustion engine and a second time period during which electrical energy is provided by the alternator to the battery;
determining, by a processor configured to process the plurality of battery voltages, first and second battery voltages during the engine starting event, the first battery voltage being a minimum battery voltage during the first time period and the second battery voltage being a battery voltage during the second time period when the battery reaches a steady state for recharging the battery;
determining, by the processor, a battery state based on the first and second battery voltages, wherein determining the battery state comprises:
predicting, using the first and second battery voltages, a future failure of the battery to perform during a future engine starting event; and
providing, by the processor, a warning regarding the battery state, the warning indicating the future failure of the battery.
