How to install BTI Replacement Battery RBC59 for APC

  • Step 1: Power down the UPS and unplug it from the wall outlet. If the unit is connected to equipment, disconnect the load and allow any active devices to complete their shutdown sequence before beginning.
  • Step 2: Remove the UPS cover following the manufacturer’s safety guidelines. Locate the battery compartment and verify you are accessing the correct RBC59 battery area for replacement.
  • Step 3: Disconnect the existing battery terminals one at a time, noting the correct polarity. If there are any color‑coded cables or protective caps, remove them carefully and set them aside for reassembly.
  • Step 4: Install the new RBC59 battery by aligning the connectors and ensuring proper polarity is observed. Secure the battery firmly in the compartment and reattach any terminal covers or fasteners that were removed during disassembly.
  • Step 5: Reassemble the UPS cover, reconnect the unit to AC power, and perform a self‑test or runtime check to verify that the new battery reports a healthy status. Allow the UPS to charge the battery fully before putting it back into normal service, and monitor the first few discharge cycles to confirm reliable performance.

So excited for results, feels like it’s working!
Size: Medium, Unit Count: 4
First time trying them right now as delivered today. Originally thought was supposed to wear all night but glad to find out 30 minutes just because my dog sleeps on my feet over my sheets! These silicone socks feel great and I trim my toe nails short enough they seem very durable and unlikely to rip like the pic review shows. I am confident my feet and heels will much smoother after first time wearing! I do have acrylic nails so I will be careful Putting the silicone socks on and off. Just as easy as the video the spread the lotion inside the socks and rub it around, mess free!!

Actually, better than I expected!
Size: Medium, Unit Count: 4
These are better than what I was expecting based on the reviews. I do put them on carefully because someone said you can’t tear them so I’m careful putting them on, but they almost don’t feel like you’re wearing anything as long as you don’t put them too tight on your toes. I can put lotion on my feet and I know it has to soak in because there’s no place else for it to go like socks or my bed.

So so...
Size: Medium, Unit Count: 2
They do what they advertised. You can NOT walk in them you will stretch them and pop a hole in them. You cannot sleep in them unless your going to wear larger cotton socks with them to keep them in place. They are easy to wash and dry which is nice. I will need to buy another pair. Great if your gonna watch a movie or binge TV in.

Great for dry feet or to help lock in moisturizer or medication
Size: Medium, Unit Count: 2, Size: Medium, Unit Count: 2
They’re stretchy and don’t feel goopy, I use them daily and they’re working great they keep my feet nice and hydrated and soft. I’ve been using them along with lotion to help hydrate my skin so they aren’t rough during the winter. They are comfy and if you must get up they’re grippy and don’t slip or slide they stay put. They’re super easy to put on and take off.
