Does my Smart-UPS have "Hot Swap" batteries?


Does my Smart-UPS have "Hot Swap" batteries?

Product Line:



All Smart-UPS models, with user replaceable batteries,  All Serial Numbers
This includes all models with part numbers starting with SU,SUA,SMC,SC,SMX,SMT,SURT,SRT, and SRC


Customers may wish to replace the batteries in their UPS without turning off their attached load. We call this feature "Hot Swap Batteries".


Since our introduction of user replaceable batteries in 1995, all Smart-UPS products have featured hot swap battery modules. This means you can safely remove and replace your battery module without affecting your load. It is important to remember that during the brief time that your battery is disconnected, you will have no battery back up available should a power event occur. Because of this we advise that you never hot swap a battery when your power is unstable. If you are experiencing severe weather conditions or your UPS is frequently switching to battery/regulating voltage, we recommend you wait until conditions stabilize. 

Once your battery is replaced you should allow it to charge to 100%, then run a self test:  
  • Legacy Products (No LCD Display) - Press and hold the "I/Test" button. Let go once the UPS switches to battery.
  • Next Generation Products (LCD Screen) - Go to the "Test and Diagnostics" menu, then select "Start UPS Self Test"
When the self test is complete the Replace Battery Indicator should turn off.
