## Questions & Answers

**Q: Will this battery work in the apc ups es 550?**
A: Yes, it works in my ups es 550.

**Q: Will it replace apc back-ups 450va be450g**
A: I replaced a battery in one of my APC units and discovered that the fit is so precise that I had to use a metal file to reduce the overall width by about .005".  Even then it was a very tight fit.  There will always be variations / tolerances in manufacturing.  I discovered that it was not worth replacing the batteries.  I can purchase new UPS type battery backups (typically on sale) for about the same price as a replacement battery and not have to struggle with hand-fitting issues.  I know that those who sell these replacement batteries will not be thrilled with my feedback / assessment.  However, I am a handyman, have an extensive background in manufacturing and so on.  I use about five UPSs currently in my house right now.  I no longer purchase the APC brand because other brands work just as well and I can usually find them on sale.

**Q: Will this battery work in the APC back up cs 500?**
A: Yes, google is our friend.

**Q: What is the size of this product rbc2?  the amazon web site shows 7 x 8.5 x 3.5 in?    apc web site shows rbc2 5.94 x 2.52 x 3.7in**
A: It is as the APC web site shows, 5.9 x 2.5 x 3.7 inches

### ⭐⭐⭐⭐⭐ Battery for APC Back-UPS BE500U-cost more but reliable
*by T***. on December 17, 2025*

A great replacement battery for my APC Back-UPS BE500U. Until my UPS completely fails, I will continue to purchase these replacement batteries.

### ⭐⭐⭐⭐⭐ APC Battery Replacement
*by U***Y on January 26, 2026*

Replacement uneventful. I have all my PCs on a UPS but the batteries don't ladt forever. Replacement was simple and even a year later still works just fine.

### ⭐⭐⭐⭐⭐ NAME BRAND APC BATTERY MAKES MY Back-Ups UPS like new again
*by A***E on November 5, 2025*

After 4 or 5 years, "defective battery" alarm came on on my APC brand UPS. Instead of having to lay out hundreds of bucks for a replacement Back-Ups, ordered replacement battery, which arrived quickly. It took me about 5 total minutes to open the battery compartment, unplug the old battery and slide in and plug in the replacement. Perfect fit, and immediately worked like new. Because of "dirty" local power I use an APC Back-Ups on each computer to prevent power fluctuation damage to drives and office network. I guess if it wasn't important, I would have bought a cheaper generic replacement, but for important applications I stick with brand (and have never been dissapointed)
