APC Smart-UPS Hot Swappable Batteries


Are APC Smart-UPS hot swappable?

I am in an environment running many different kinds of APC Smart-UPS, including various models of the Smart-UPS 2200 and Smart-UPS 1500 series. Some UPS have experienced battery failures and require replacement batteries. I want to make sure it is safe for myself and for the UPS to hot swap the battery, but I haven't been able to find this information through APC's website or the UPS manuals.

I have several APC UPS units at my clients and in my home office. I do not hot swap batteries. If the power goes out while you have the batteries out (Murphy's law), then all is lost.

A number of units I have put batteries behind one another so both or all batteries have to be removed to get at the back battery. It is not usually fast to replace all the batteries.

I turn the equipment off, change the batteries and restart. I suggest you consider doing the same.

Quite sure that both 2200 and 1500 are hot swappable.  It's a bit impractical for units up in this range not to have that ability.  Did you look at the manual's battery replacement procedure.  The one I looked at clearly says they are hot swappable,  might not be the exact same model.  The spec's section did not say anything though.

Obviously the unit will fail if a power failure did occur while you have the batteries disconnected.  Certainly worth considering the potential risks if this did occur.

About the only dangerous thing would be to mess with the connections while a UPS is running on battery.  The battery connections run at very high load and you could see some big sparks and arcing,  possibly ruin connectors or causing injury.

Agree with both comments ... (a)  You CAN hot-swap the batteries;   but (b)  I wouldn't do it.    It's simply much safer to shut down; UNPLUG the UPS;  swap; then turn everything back on.

Although if the batteries are in a fail state now,  there may not be much added risk as the UPS may be of little or no benefit if the power fails anyway and do need to be replaced ASAP.  

Something else,  if you happen to have units with external battery pack connections (I think it would be XL models of the SmartUPS).  The internal batteries can be changed while the external pack is connected.  If the power failed the external pack will keep things running.  Still DO NOT reconnect a battery while the UPS is in the power fail state though.

Usually this option costs a bit more so probably only have XL units if you needed longer runtimes.
