The UPS batteries are subject to a reduction in capacity depending on their age (a
feature declared by their manufacturer in the technical manual). For example, the
reduction of capacity of a 4-year-old battery can be as much as 40%, resulting in a
proportional reduction of UPS autonomy time when running on battery power.
