How about Tianneng battery? Is the battery good?

Tianneng battery is of good quality. Tianneng battery has extremely low self-discharge rate and large discharge current. Some batteries have the defects of narrow working temperature range, easy water loss and thermal runaway. Tianneng battery has stable performance, wide working temperature range, overcharge and overdischarge resistance and long service life. Caution: Excessive temperature environment will increase the internal pressure of the battery, forcing Tianneng battery pressure limiting valve to open automatically, resulting in increased water loss of the battery. Too much water loss of Tianneng battery will inevitably lead to the decline of battery activity, accelerate the softening of pole pieces, and cause fatal injuries such as heating, bulging and deformation of the shell during charging.
