摘要： A liquid level sensor for a liquid electrolyte battery is provided. The liquid level sensor includes a probe having a reference electrode and an electrode array. The electrode array includes a plurality of electrodes that are serially disposed in a lengthwise direction of the probe. The reference electrode is capacitively coupled to each electrode within the electrode array, such that the probe provides a capacitance that varies when the probe is immersed in a liquid level that varies in relation to the probe. The liquid level sensor can alert a user of the need to refill the battery or alert a user of the need to refill the battery in the near future. The liquid level sensor can include a series of LEDs that selectively illuminate to indicate each such condition to the user.
