Backup Pro 1500S not giving the same projected runtime anymore.
I've had this UPS for years. The projected runtime was always 72 minutes in the day, 68 minutes at night.
1.5 weeks ago, I lost power for about 2 hours.
After the power came back on and the battery charged, the projected runtime was 39 - 45 minutes.
I then bought a new battery, and replaced it. It's been more than a day, and even with the new battery, the runtime is 39 - 45, about 1/2 of what it used to be.
If I have to disconnect equipment from the UPS, how do I disconnect the equipment so I don't lose power to the connected devices?

Whenever the battery cartridge is replaced the following steps need to be completed to obtain the most accurate information and operational runtime.
- The battery installation date must be updated in APC PCPE / PCSS software. Doing so resets internal counters and charging tables.
Self Test: Manually initiate a self test either through the LCD MENU / APC PCPE / PCSS software.
Battery Calibration: Manually initiate this procedure with at least 30% attached load and let it complete and recharge.
The operational runtime will be more reflective on the display. Keeping in mind this value is variable based on battery SOC, health, usage, temperature, load.
