Greetings,

I need a replacement battery for a BN575G.  This model is not listed on the battery replacement page.

What is a supported replacement for this model, and where can I find it?

Thanks,

The official battery replacement is listed as APC RBC110 as seen here:

You may purchase any 12 VDC cell with the same outer dimensions as this is a very common size.

Your specific battery is a 7AH rated cell but would humbly suggest you upgrade to a 9AH cell for longer operational runtime.

If you have more questions please ask. If not and the information was accurate and provided the solution please mark this reply as so.

So the same information can help the next person asking the same. 👍

Ok, thanks.  I picked one up and I'm back in business.

Just like that? Are you sure that the ratings of electronic components, wires cross-section, charging logic, etc. are intended for 9 Ah?

Yes replacing the original 7 AH RBC with a 9 ~ 10 amp hour cell will provide longer operational runtime during a grid down / lights out event.

This is done by every major UPS maker in the world. 

This doesn’t change anything in the APC UPS as to how it operates, charges, or reacts to an outage.

No internal wires will see more current as nothing has changed as this is all managed by the system.

The system will simply run longer because the RBC has more capacity! The important steps when replacing any RBC is updating the installation date if available as this resets internal counters and adjusts charging tables.

Next, manually initiating a self test and letting it pass and RBC to recover. Followed by manually initiating a Battery Calibration with a minimum of 30% load.

Once this procedure is completed the displayed operational runtime will be more accurately reflected on the LCD, PCSS, SNMP.
