SMT2200R2X106 Battery Replacement

[Anonymous user]

We have three SMT2200R2X106 UPS devices powering our core switching and domain controllers. They have been running for nearly three years now and we're looking into replacing the batteries. Can we replace them without powering down? If so is there a resource explaining the process? Thanks!

Yes, the batteries can be replaced without powering down. You'll want to have the replacement batteries ready for immediate installation, as the load will not be protected against a power failure until the batteries are reinstalled.

Gently pull outward on the front bezel to remove it. At that point you should see the battery door.

The user's manual for your UPS will have complete details (some of mine might be a bit fuzzy, I'm going from memory). Unfortunately, it seems that the "manuals and documentation" link leads to a 404 not found message. Hopefully someone at APC might be able to fix that.

The RBC43 is one of the easiest battery cages to replace.  Remove the bezel, remove the three mounting screws, disconnect the blue Anderson, slide it out, slide the new one in, reconnect the blue Anderson and screws and then your done.  You should reconfigure the SMT so that it knows new batteries have been installed.  If the old battery packs have lost run-time, you might have to recalibrate the new batteries.  Just be careful - if you have the units fully loaded,  the battery can be depleted very quickly and shutdown the unit if you don't get the mains back in quickly toward the end of calibration.  A ~ 30% load is best.

These battery cages can also be "rebuilt" with new batteries quite easily.  They use 8 - 12 volt, 5 (or 5.5) AH batteries available at places like Battery Shark -  fairly inexpensively.  It does take some knowledge of batteries, polarity, and DC wiring, so don't do if you don't have such skills.

Good luck
