Rated 5 out of 5 by from With the premium I've purchased refurbished batteries before, and they never last as long or work as well as the APC brand. It's definitely worth the higher price. Installation is simple and quick.

Rated 5 out of 5 by from it works Second order got the correct battery. Order showed up but now return mailing for battery disposal. They brag about this when calling in on hold as to why purchase from APC but when you do they forget that part. I you want to dispose of the battery you must call an E-waste company or deliver yourself or you could make several phone calls and e-mails to APC and get the UPS return label. So if the deal is better somewhere else you might want to take it.

Rated 5 out of 5 by from Reliable Replacement Products We've sold many of these over the years and can't recall any complaints about the product quality. 3-4 years on these seem more than likely based on time between orders. Can't imaging wanting to go with non-APC on something like this - whatever you pay is worth it for peace-of-mind in my book!

Rated 5 out of 5 by from What is it? I am trying to get batteries. Everything I read in the webpage is for batteries. The picture is for a battery cartridge that hold 4 batteries. I severely hate confusion and stupidity. If it is a battery then I should see RBC43 batteries itself.

Rated 5 out of 5 by from You Need This!!!!! The power blips for a second in the building we are located in every now and then. With-out APC, important servers and data would be put in peril. Luckily with APC, things have been rock solid 24-7. I was emailed a battery failure warning and quickly ordered a replacement. The swapping of the batteries is a walk in the park, no swelling of the old batteries like yesteryear, which made it difficult to remove the old battery. No sleep lost here!
