Over time UPS batteries wear out. This leads to a loss of power capacity and runtime. Here are four reasons why you should only use genuine APC RBCs in your APC UPS:



Use of a non-APC battery will void APC's Equipment Protection Policy



APC recycles used batteries and almost 100% of the battery lead content is reused, protecting the environment. With each purchase of a genuine APC replacement battery, you get free freight back to APC for proper disposal of your old batteries (currently available in USA only.)



APC provides a 1-year warranty on each Replacement Battery Cartridge.



APC supplies the appropriate instructions for your UPS, along with any needed wires and connectors. All connections are made with high current gas-tight crimps for high reliability.



RBC4 only works with APC UPS Models BK650MUS, BK650X06, BE750BB, BE750-CN, BE750BB, BP500JPNP, BP650PNP, BP650S, BP650SC, BP650SUS, SU620NET, SUVS650, SC620.

Rated 5 out of 5 by from Good deal for needed product I have had my Pro 650 battery backup for several years & just bought the replacement. The price was fair with free shipping and recycle return of the old part. I am on the coast in a windy area so power is often flickering. This battery keeps me running without a power failure.

Rated 5 out of 5 by from APC's batting average is now .999 I ordered a RBC4 online...got free shipping with a coupon code! The new battery got here quicker than I expected. The product is excellent. So why isn't APC's batting average 1.000? I received two pages of recycling information for the old battery, instead of the prepaid mailing label I expected. I'm not angry, just mildly disappointed. APC's products remain the Gold Standard in the field.

Rated 5 out of 5 by from No supprises installing The fit is tight and cables short, but put it on a tabletop and all will go well. UPS had no issues with finding the new battery. Having the prepaid label to dispose of the old battery made things tidy.

Rated 5 out of 5 by from Close to 20 years with APC I am a US Navy veteran, and ever since I left the service in 1992, I have always used APC UPS equipment to protect my home electronics, specifically my computing equipment. I have never had a problem with equipment operation, their UPS devices have always exceed their rated time before needing to change batteries, and their battery recycling service shows an excellent sense of responsibility on the part of the company to protect our environment. This particular battery replacement was for the UPS for my wife's computer. The UPS was able to notify us in advance that the old batteries failed their self-test (after close to 6 years of continuous use), and that battery replacement was required. Nonetheless, it was still able to sustain operation until the replacement batteries could be obtained and replaced. Replacement was straightforward, and the device has been operating continuously and incident-free since the replacement took place. I might be getting spoiled by APC's excellent customer service and quality products, but I don't see myself switching to a different brand of UPS any time in the near future, if ever. I always highly recommend APC products to my friends and peers in the IT industry. Kudos for excellent product quality and outstanding customer service!

Rated 5 out of 5 by from Easy to install! The APC replacement battery was easy to install and we haven't had any issues. I advise going with APC vs a third party. APC is more reliable.

Rated 5 out of 5 by from Battery A bit difficult to reconnect the replacement battery. Longer wires on the battery would help. Otherwise, everything is fine. The reusable packaging and list of disposal locations in my vicinity was great help. I also love the new POWERCHUTE software.

Rated 5 out of 5 by from Product good but ... ...I was disappointed to find no UPS label for returning the old battery for recycling. Was this simply an error, or has APC changed its policy? Otherwise, I am pleased with the UPS unit and the battery. They operate as I expect; no concerns here.

Rated 5 out of 5 by from Totally Satisfied I have been using APC products for more than 10 years. My most recent purchase was a battery replacement for a BACK-UPS 650 that I purchased in November 2000. I had been using the original battery until June 2011 when I purchased the replacement. I am totally satisfied with the product performance and customer service from this company. As to the new battery, it was installed in less than 5 minutes by a neighbor who is well versed in electronics. I might have had a problem with the wiring since the terminals were reversed from the original positioning for this particular unit.

Rated 5 out of 5 by from On-Line Battery Replacement We have had APC backup for our home/small business offices for the past 10 years. When a battery needs to be replaced we just go onlline to order one. Only improvement we would like to see is timed/power sensitive message to alert the user when the battery should/needs to be replaced. That way the user never has to worry about being "exposed" if the battery has outlived it's useful life.

Rated 5 out of 5 by from Excellent Experience I'll add my two cents worth to the other reviews. We've been fans of APC for a number of years. I'm always delighted at the ease with which I can bring my unit up to date when needed. The price is reasonable and the service is great. The replacement battery cartridge arrived earlier than anticipated. The only complaint I might make is the difficulty in installing the replacement cartridge. It is a little tricky but not impossible. It seems the wiring could be changed in the unit to make the reach to the cartridge terminals easier and more intutive. Other than that - great product.

Rated 5 out of 5 by from RBC4 replacement battery Battery arrived fast and well packed, instructions were perfect. The only problem I had was that I couldn't print the return label for the old battery to be recycled using the link in the instructions. I called the APC help line and was emailed a link to a site from which I was able to print a label. The APC help was great. I certainly recommend APC and would buy from them again when i need another UPS or replacement battery.

Rated 5 out of 5 by from Replacement Battery Even though my APC UPS is ancient, they still have the battery for it. I ordered it and got it within days. It was easy to install and worked great right from the beginning.

Rated 5 out of 5 by from Extremely Expensive Battery Battery replaced in a Back UPS Pro 650. It works. It is extremely expensive for a simple sealed battery. You can buy car batteries for less! No doubt part of the business model to get folks to trade in fully functioning UPS systems. Come on APC - build a quality products and sell replacement batteries for a fair price. Do that and I'm a customer for life. In the meantime, I am moving on to your competition!

Rated 5 out of 5 by from Replacement Battery Cartridgle Buying a new battery went like clockwork. The only issue I had was in getting the new battery to fit into place. It took a little more patience than I had. Once I got it in place everything else was simple. I was able to salvage the Battery Back-Up. Disposal of the battery was easy. Lowe's took it with no questions.

Rated 5 out of 5 by from Reliable Replaced my battery in December 2010 and again in December 2013. That's reliable! My backup battery has saved me during several city power outages since I got my new computer with the ACP backup battery. I'm grateful to not have to worry about power failure any more.
