hi i have a unused unit of apc ups
i plan to sell it , but the unit already no more warranty
how do i check the unit health status and which portal i can sell to other ppl for the ups ?

ok will monitor on it
cause last time i buy with some people
they tell me this unit is rarely use
then they sell to me...
i put my house like useless

may be will try to use powerchute and test
then see the condition
