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.

Customer Reviews

350VA UPS Battery Backup is rated 4.7 out of 5 by 24.
Rated 5 out of 5 by from Great Unit Needed to replace my APC ES350. So I decided to go with this model since I have the larger 1500 versions that have been running for years without a problem. It has been a few months now using this for my modem/router and it has performed amazing. What I replaced was actually the second ES350, which honestly are junk, they typically die within a year and replacing the battery only extends this another 3-6 months before the rest dies, usually killing a good battery inside. I went through 2 ES350 models within 30 months which is abysmal when my XS1500 models have been running for years flawlessly (only need to replace the batteries every 3-4 years).
