Apc Battery Backup 550

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!

Works with my APC Backup..

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

I use this battery cartridge in my APC J10 J Type Power Conditioner with Battery Backup. There are many components plugged into this device. It gives me comfort to know that my electronic equipment is getting the right power and will give me uninterrupted service. One power glitch could cost me much more than the price of the unit and the battery. I replace the battery every 3 years and am very happy with the security that it provides me.

APC Battery backup systems are an absolute necessity for IT needs. The battery itself is very easy to instal and keeps server equipment functioning for sufficient time for the automated shut down scripts to close down all servers and equipment to save your data from damage or loss in a power outage.

Our APC Battery Backup and Power Conditioner has been a lifesaver for our electronics. We have a lot of "brownouts" where the lights don't go out but just dim which is so hard on all of your electronics. Replacing the battery was super easy and took less than 5 mins. I loved that we were able to send the old battery back for recycling too!

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

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.
