The disclosure provides a battery (10, 610), a method, a device (700) and a system for battery (10, 610) protection, which belong to the field of power supply. The battery (10, 610) comprises: a rechargeable power supply (110) and a battery chip (120), wherein the rechargeable power supply (110) is configured to supply power to an electronic equipment (620), and the battery chip (120) is configured to detect whether the rechargeable power supply (110) has started to supply power to the electronic equipment (620), and if the detection result have started to supply power to the electronic equipment (620), send a customized signal to the electronic equipment (620) through the predetermined transmitting pin. The present disclosure transmits the customized signal to the electronic equipment (620) through the battery chip (120), wherein the customized signal is used by the electronic equipment (620) to recognize whether the customized signal is correct; and if the customized signal is incorrect, the power supplied by the battery (10, 610) is controlled to be cut off. It solves the problems that the imitation batteries may lead to negative consequences in the prior art, and achieves the effects of keeping on supplying the power from the battery (10, 610) only when the battery (10, 610) in usage is guaranteed to be an original battery (10, 610) satisfying the requirements, improving the safety of the batteries and the electronic equipment (620). |
