RBC43-UPC Replacement Battery for APC UPS: SUM3000RMXLI2U, SUA3000RM2U, SMT2200RM2U, SMT3000RM2U by UPC UPGRADE PARTS COMPANY - Assembled in USA!

Awesome product very easy to install / change, fits like a glove and works like a champ, don’t worry about fit or quality these folks have got it covered.

plugs right in and worked like a charm. Buyer has to pay shipping to return old battery for recycling unlike APC.

Batteries are a tricky business. There are lots of batteries in the market with the same specifications but not necessarily the same lifetime and performance therefore I like this original factory unit. It is also easy to install without disconnecting the UPS power. On the down side It is quite heavy for one person to handle and there is a lower cost alternative of replacing the internal batteries in the existing module, although for most users the cost saving would not justify the extra labor and the risk of a failure.

I have purchased four of these, but all of them have failed in a short timeframe, two failed in less than 12 months. I returned one to the seller UPC - Upgrade Parts Co. at my shipping expense just to have them stop responding and I have never received a replacement. The other that failed in less than twelve months I didn't return at my expense since I never received the first one back or any communication from the seller after getting the RMA, shipping the unit back, and sending them the tracking information on the first.The units are built well, but the batteries they are using in them fail quickly.

Slid right in and has been working perfectly for the past month or so. What else is there to say?

I have several APC Smart-UPS 3000RM units installed on customer's yachts, and have used these replacement batteries multiple times.3 out of the last 4 I've purchased have worked perfectly, but one failed in about 10 months.Keep in mind that units installed on boats see harder-than-normal use, as they experience generator power and dirty "shore power" in various harbors.... so I'd overall give these 4/5 stars.

While I appreciate the convenience of a "plug and play" battery installation, to have a pack of lead-acid batteries last only 18 months was a big disappointment to say the least. Sadly, this is a case of you get what you pay for. I will buy branded batteries in the future and do the installation myself. These things should last 3 years at least.

Works great, been in use for 6 months now, no issues yet.
