What is the self-discharge rate of this battery and is it suitable for applications requiring long-term storage?
Ni-MH batteries, as a rechargeable battery, have a relatively low self-discharge rate, which means that the battery only loses a small proportion of its charge over a period of time when not connected to any load. Typically, Ni-MH batteries have a self-discharge rate of about 1-3% per month. This relatively low number reflects the relative stability of this battery technology in maintaining energy storage status.

For applications requiring long-term storage, Ni-MH batteries are considered one of the suitable energy solutions due to their relatively low self-discharge rate. A low self-discharge rate means the battery maintains a relatively stable charge level even when not connected to a device. This is critical for many application scenarios, especially those requiring backup power on standby for long periods of time.

Although Ni-MH batteries perform well in terms of self-discharge, in order to ensure their optimal performance and longevity, some maintenance measures are still required when stored for long periods of time. Regular inspection and charging are critical operations to prevent the battery from being in an over-discharged state. Even if the self-discharge rate is low, long-term non-use may still have a certain impact on the performance of the battery. By charging regularly, users can ensure that Ni-MH batteries can provide reliable power output when needed.

One of the advantages of Ni-MH batteries is their relatively low environmental impact. Compared with some other battery technologies, Ni-MH batteries do not contain environmentally harmful heavy metals such as cadmium, so they have certain advantages in terms of environmental protection. This provides a saving grace for some application scenarios that require higher environmental friendliness, such as renewable energy storage systems.

In addition, the low self-discharge rate of Ni-MH batteries makes them excellent in certain application scenarios, such as wireless devices, emergency backup power supplies, and portable electronic devices. In these scenarios, users usually expect batteries to maintain energy storage status for a long time, and the self-discharge characteristics of Ni-MH batteries meet this demand.
