  • Patent number: 8330467
    Abstract: A measuring device is used in conjunction with a programmable controller for monitoring electrolyte levels in the battery. According to one implementation, the measuring device is located in a battery and is configured to detect when the electrolyte level in the battery falls below a particular level. The controller is in electrical communication with the electrolyte detection device. The controller is configured to: (i) receive a signal from the electrolyte level detection device indicating when the electrolyte level in the battery has fallen below the particular level; (ii) introduce a wait-period after the signal is received; and (iii) enable an indicator to indicate that the electrolyte level in the battery should be refilled when the wait-period expires.
    Type: Grant
