You really have to know a little something about APC UPS. The battery came with no real instructions. When I replaced the battery the alarm went off on power up and stayed on. At first I thought the battery was DOA, but I remembered seeing this before. The batteries ship totally discharged. Upon "boot" of the UPS it checks the battery condition. It mistakes a totally discharged battery as a short. The high surge of current caused the UPS to "stink" as it charged the battery. After a few minutes it began to work fine.
Keep in mind this can happen when you replace your battery.
