Ano kayang UPS gamit nila? bakit hindi replaceable yung battery?
or baka lithium yung battery ng UPS nila naka solder sa board
my wild guess is,
them batteries can be replaced, and are designed to be replaced.
but if the user does not know how to maintain his own equipment nor care enough to know...
what did someone say?
"if you think education is expensive, try ignorance!"
