<p num="1"><br/><br/><br/>There is disclosed a storage battery which is capable of self-monitoring by <br/>detecting and indicating the actual capacity and the expected remaining life-<br/>span of the battery, the condition of its charging system and the discharge <br/>level. The battery is provided with an integrally assembled detection and <br/>indicating means which measure the actual potential across its terminal <br/>(indicative of the state of charge of the battery) and the internal resistance <br/>of the battery (indicative of its health). The expected remaining life-span of <br/>the battery is derived from the calculation of current from these <br/>measurements. The battery is assembled to include a casing (2), a cover (3) <br/>and a capacity detection and indicating means. The detection and indicating <br/>means consist of an electronic circuit that measures the electromotive force <br/>and the internal resistance of the battery and indicate the same on a display <br/>means (9). The display means is adapted to exhibit whether the battery is in <br/>good working condition or otherwise during engine off or whether the charging <br/>system of the vehicle is in good working condition during engine in operation. <br/>Further, it could also monitor potential leakage presence in its electrical <br/>system.<br/>
