there's 3 types of UPS:
- offline (the low end cheapest)
- online (most expensive)
we already know that batteries of both online & line-interactive UPS last longer than those of offline UPS
The on-line ups's only draw what they have to from the battery system, to make up the difference.
same for the line-interactive ones they too can regulate voltage without using the battery
hence my question: do batteries from online UPS also last longer than those of line-interactive
(not offline) UPS?
and if so why?
