Abstract

The invention discloses a battery discharge indicating circuit. The battery discharge indicating circuit comprises a battery, a discharge circuit connected to two poles of the battery and an indicating circuit connected to the discharge circuit in parallel, wherein the indicating circuit comprises a first switch element, a first resistor and an indicating element; the first switch element, the first resistor and the indicating element are connected in series and are connected to the two poles of the battery; the battery discharges when the discharge circuit is switched on; and the indicating element indicates whether the battery discharge is completed or not through lightening when the first switch element is switched on. The invention also provides a battery discharge indicating device.

Description

technical field [0001] The invention relates to a discharge indication circuit system, in particular to a battery discharge indication circuit. Background technique [0002] With the rapid development of computers, the performance of computers is becoming more and more powerful, and the applications of computers are becoming more and more extensive. The motherboard battery is an important part of the computer. It is used to record the system time of the computer, that is, to maintain the accuracy of the system clock. That is to maintain the bios information of CMOS. The motherboard battery usually needs to detect the discharge time, however, there is no suitable indicating circuit at present. Contents of the invention [0003] In view of the above, it is necessary to provide an indicating circuit for conveniently indicating the discharge state of the battery. [0004] A battery discharge indication circuit, comprising a battery, a discharge circuit connected to two pole...
