6.5.3 Replacement 1) Replacing Criterion
Replace the battery if its capacity measured during the battery test is less than 80%
of the battery rated capacity. The capacity measured during the battery test shall be
evaluated at a discharge rate close to its actual use.
2) Replacement Interval
The battery is expendable, and has a certain life cycle. Considering the use
condition and ambient temperature, the new battery should replace the old battery
before it reaches its design life to ensure the normal and safety operation of the DC
power system. For instance, in an environment where the mean temperature is
35°C, it is necessary to replace the battery every 5-year operation.
