Apc Backup 550 Manual

Works with my APC Backup..

Installed this as a replacement battery to the APC Back - UPS 550 or 650 unit. Works great!

My APC Backup unit told me through the main unit that it had a low battery for the backup unit by a red lit signal that went off every 4 seconds. I had to replace the battery to stop the beeping. When it arrived, it was well packed and had a return label for the waste disposal of the old battery. The installation of the new battery was not as difficult as getting the old battery out of the unit - it was a very tight fit. Now that it is installed, the beeping stopped and life is back to normal. YEAH!

OEM battery fit perfectly into APC Backup & operated per design.

This was the second replacement for my APC Backup. Very easy to install ( 30 seconds). Priced just right.

My APC battery backup died. For a fraction of a new unit B&H shipped me the new battery to get me back running.

Been over 3 years now , out of warranty . needed new battery . Read user paper manual page 8 ,...Battery is replaceable , Page 8 implies APC does NOT recommend the End Consumer to do it . Instead , page 8 recommends an SEIT Service Center to replace the battery . The paper user manual says to take the unit to a Service Center for battery replacement , NOT to a recycle center . Please , read the manual . APC may or may not approve , but i just dropped in a CSB GP 1272 F2 7.2 ah battery. BN450M is better then ever at near 200 watt load . BN450M delivers the goods at 200 watts , when paired with a proper battery . Purchase strategy : If you have No ups , then get the BE650G1 as it comes with a 9 ah RBC17 battery Which will easily run 200 watt loads . If your BN450M is now out of warranty , I recommend replacing the battery at your discretion . If i knew what i now know , i would have gone for the BE650G1 ( to get that larger battery )

This replacement battery for my APC power conditioner and battery backup is exactly as the original OEM battery. Delivery was prompt and arrived as estimated. I highly recommend B&H.

My APC 1500 surge protector with battery backup went defective. Self check test showed battery failure. Rather than replacing the entire expensive backup, I merely ordered this #124 replacement battery and replaced the original one for allot less cost. It now works good as new. Simply, side the old battery out and slide in the new one and that's it. I did not know replacement APC batteries were available until re-reading the APC instructions and by APC web site research.

I've been very happy with my original purchase of the APC backup unit. It has come in handy more than once! Thus, it was a "no-brainer" when I needed to replace the battery cartridge. The replacement enables the backup unit to continue to provide backup when necessary.
