Do my company had a brand new APC SMT1500 RM 2U UPS that was in the store for long time now. We now want to use it but the batteries are not charging.
Is it possible that the batteries can run out without being used? What are the possible causes? Please help
Posting your serial number will help determine the age of the unit. You can also find a serial number on the battery to help determine its age.
