Smart-UPS RT 5000 battery calibration question

[Anonymous user]

 Hello, I have a Smart-UPS RT 5000 model and I'm trying to run a battery calibration on it. The question is that during this process the load (which consists of server and other network equipment) will be shut down ?

Hello Andrei,

There are two types of calibrations - Manual and User Commanded and depending on the method that you will use, there is a possibility of load drop.

User Commanded:

• This is the preferred method for all Smart-UPS except for models beginning with SU (IE: SU700NET). 
• Calibration is initiated from Power Chute Business Edition, the Network Management Card, or the LCD Screen of the UPS (if so equipped).
• Ensure that the normal load is attached
• Ensure Battery is charged to 100% before beginning Calibration
• Load should be more than 30% for best results
• UPS will drain the battery, then switch back online and charge back up
• Calibration must not be interrupted to deliver valid results

Manual Calibration:

• This is the preferred method for "SU" series Smart-UPS, or any time that a User Commanded Calibration is not possible
• Stop the Power Chute software from running and disconnect the serial, USB, or Ethernet cable(s).
• There must be at least a 30% load attached to the UPS during this procedure, and this load cannot fluctuate more than +/- 5%. THIS IS IMPORTANT
• Attach a non-critical load to the UPS and then force the UPS on battery by disconnecting it from utility power
• Allow the unit to run on battery until it turns off completely. The load attached to the UPS will drop.
• If the Load is not at least 30% or if the calibration is ended before the UPS drops the load, the calibration will not work.
• Plug the UPS back into the wall outlet and allow it to recharge (preferably turned off)

Thank you for the answer...so If I understood correctly If I initiate the calibration procedure from the web interface (method 1 ) it won't have any load drop ?

That is correct Andrei.

Sir my question is not about calibration.. My question is up to how many battery packs can a Smart UPS SRT5000KXLI can support? Because i installed 2 battery packs already and on the third battery pack when I plugged the third battery pack it gives me an error of over voltage or something. Also if I update the firmware of UPS will it give the setting that i can install/mount more battery packs? Coz in the product manual i have read that it can support up to 10 battery packs.. Thank you sir..

I have 8 battery packs running on a similar model UPS. I'm thinking if you received an overvoltage??? that to me would indicate a voltage problem in that particular battery pack, maybe something is not wired correctly, usually you have about 52 volts DC from each group o4 4 batteries, 4 * 13 = 52 volts and each deck has 2 sets of those batteries. Im thinking I would measure the voltage on that one deck. Batteries would not otherwise be overvoltage unless maybe hooked up wrong internally?
