期を適確に判断することは難しくなる。Generally, a battery has a characteristic called a cycle life characteristic, and its life ends after repeated charging and discharging a certain number of times, so at this point it is necessary to replace the battery with a new one. This number varies depending on the discharge rate as shown in Figure 2.1For example, 100% discharge is 180 times, 50% discharge is 420 times, 30% discharge is 1220 times, and so on. Cycle life increases as the rate decreases. As described above, the lifespan of a battery varies greatly depending on the conditions of use, making it difficult to accurately determine when to replace the battery.
