Customer Questions & Answers

Can I purchase a replacement battery for the UPS I bought?

The APC CS350 requires a replacement battery (BK350) when they get old and no longer hold a charge. Where can I purchase the replacement battery, and if Home Depot carries it, how much does it cost?
Asked by: Anonymous
Thank you for your inquiry. The normal life of the battery should be anywhere from 3-5 years depending on battery usage, load percentage and operating environment. If your exact UPS model number is BK350, then the replacement battery part number is RBC2. The UPS model number is located on a white bar code sticker on the back of the unit.

Rated 5 out of 5 by from On March 5, 2011 a huge thunderstorm with hundreds of lightning strikes caused a main power line to fall in the alley. It sent 7200 volts into my home. Blowing out the master breaker and the complete breaker panel. I was working at the computer when I heard the blast in my house and all the lights went out except my computer. The BK350 kept everything running until I shut it off a few seconds later. It protected the Computer, Scanner, Printer, Work Light and a Radio. Two days later when our system was restored I turned on the computer. It would come on, but not stay on. I hit the reset button on BK350 and it exploded internally. I removed it and put a backup in place and the computer ran fine. It saved my computer and accessories.

Rated 4 out of 5 by from Adequate but expensive I assume this product will work well when needed. APC products generally do. However, I have 1 gripe and 1 kudo. Good: a paper with the model & serial numbers is taped to the side of the unit. This is handy for registration. Avoids need to remove plugs to read sticker. Bad: despite bragging that they have room for 2 transformer plugs, they do not. At least not if one is a 2 blade style. Mine covers other plugs.

Rated 5 out of 5 by from Excellent Product We installed 5 of these about a month ago. We had a power outage on 10 June 2010 and they worked exactly like they were supposed to. Very smooth transfer to the APC, just as smooth when power came back on in 10 minutes. We are very happy to have installed these before our usual round of power outages, they usually occur once every week or so. Keep up the good work.

Rated 5 out of 5 by from Best Yet Bought this unit to replace one we had for over 12 years. This is more compact and looks so much better. It was easy as pie to hook up and has been the best. Looking forward to another 12+ years with my APC!

Rated 5 out of 5 by from Works as Promissed I bought this for my daughters desktop because her last one was damaged when the power went off several times which happens in our area. This has helped save the computer many times.

Rated 5 out of 5 by from CS 350 I've owned mine for 4 years without issue until now. The Battery cracked, but didn't leak into the unit. Even with a cracked battery it still worked, only found the problem while cleaning the dust out. The replacement only costs $39.00 and will buy it now to keep using the unit.
