Looking for clear, definitive instructions on what to do after replacing battery on SMT1500C

This question was originally posted by Meccano on APC forums on 6/5/2020


I've now spent several days searching the Internet and APC and I still can't believe I am left as confused as I am.

I tried contacting support and am still waiting to hear back.

My SmartUPS is the SMT1500C. It has the latest 4.1 firmware.

I've found plenty of instructions and videos on how to physically replace the battery. That's fine, I already know how to do that.

But that's where they stop. I'm unclear what to do to "tell" the UPS that a new battery has been installed.

I find references to "resetting the battery constant." But these instructions are quite old and the few results seem to be copies of the same instructions. Apparently this is something that can only be done with a serial cable and COM port? (Seriously?)

I found this, where APC gives the instruction, "...manually select 'Install New Battery' from the configuration menu..." Well, there IS no "Install New Battery" option on the configuration menu. (You can search the user manual for "install new battery" and it finds nothing.) On page 18 of the manual, it references a configuration setting called, "Date of Last Battery Replacement - Date set at factory. Reset this date when the battery module is replaced." I have no idea if this resets the battery constant or does anything else other than just setting a date.

I understand there is a calibration procedure. The manual references it on page 16 as part of General Settings and again on page 17 as part of Advanced Settings, but it gives absolutely no other info or instructions. My understanding that I've gotten from different sources, is to plug the UPS in, let the new batteries charge to 100%, then attach a load such as a halogen work light to the UPS, select the "Calibration" option, then turn the load on. The load is supposed to drain the UPS, then the UPS charges the batteries back up once they are drained. This is supposed to give it accurate info about the batteries, but I have no idea if this resets the battery constant, if this needs to be done before or after setting "Date of Last Battery Replacement", or if ANYTHING else needs to be done.

So all I've really been able to just guess so far is:

1) Replace physical battery,

2) Set "Date of Last Battery Replacement" on configuration menu,

3) Run Self Test,

4) Run calibration

Is that correct? If not, can SOMEONE PLEASE provide CLEAR steps of the correct procedure?

Recently, I replaced the batteries in my SMT1000. I was trying to maximize the runtime, so I fully charged the batteries externally. (You should only attempt this if you have a good battery charger or a power supply and you know how to do so.) After I installed the batteries, I DID NOT run the self-test, because it puts a load on the batteries. I connected a non-inductive load (PF 1.0) that was 50% of the load capability of the UPS. (I used lights and verified the PF using a kill-a-watt.) Then I ran the calibration. It depleted the batteries to around 15% and the runtime was as expected.

Hi Meccano,

We are looking into this - can you let me know any reference from your contact with support (e.g. case number) and we will get back to you via the support case. Thanks.

Hi Meccano,

The option to change the battery install date on the UPS LCD display menu has been removed with the addition of the SmartConnect feature - the user manual is in progress of being updated.

During the battery replacement process, after disconnecting the old battery and connecting the new one, the UPS LCD display will prompt to select whether this is a new battery or not. Selecting yes will allow changing the date and saving the new date as the battery install date.
