1. A method for determining polarization of an electrode of a VRLA battery, the method including the steps of:

  • allowing the battery to discharge for a selected period of time, monitoring the battery voltage during the selected period, detecting a first change in the battery voltage during the selected period of time and a second change in the battery voltage during the selected period of time, and associating the first change with polarization of a negative electrode and the second change with polarization of a positive electrode, and determining the polarization of the electrode from the associated change in the battery voltage during the selected period of time.
