The battery pack works fine, and is installed in my unit after a bit of jerry rigging. Make sure you have the NEW version of the XS 1500, not an older one, or this won't fit out of the box.

I purchased this model for my APC Back+UPS XS 1500; which is what the product description says it fits. My XS 1500 is several years old (purchased it at Circuit City back in the day), and apparently APC has kept the same name as the older models, but changed the design of the battery packs.

The issue is that in the older XS 1500, the two batteries that make up the pack are side-to-side, with the terminals at the top of each unit on the same plane. With the version shipping with this product purchase it's the same two batteries, but instead of side-to-side, they are top-end-to-top-end and held together with binding cover.

It only took a few minutes to disassemble the thing as received and put it together (with strong electrical tap binding the two batteries together) in a manner that fit the older unit. Once inserted and connected, it charged right up and my UPS is actually a UPS again.

Overall not a big issue for someone with just a little bit of tech saavy...but also not something the average user would want to deal with.

UPDATE: Time to order another one for my APC XS-1500. The item advertises 3-5 years battery life, and I'm just one month short of the 3 years mark. I'm not going to down-rate the product because of that, but wanted to warn others that this product is probably going to be on the low end of the battery longevity scale advertised.

I just got my shipment from UPS and I'm not a HAPPY CAMPER as I ordered the real APC RBC33 pack as listed on Amazon. What I got from the company they used call chefash was 2 separate batteries. Now the Amazon page shows I ordered the real deal, but Chefash is now listed in the other companies. When you look there now they say it's 2 separate batteries which is not going to be APC as they only ship the batteries as a unit (taped together and you get a free shipping label to recycle the old batteries). Not from this place! I blame Amazon for showing the APC just like now, only saying it ships from Chefash and nowhere when I ordered did they list if as two separate batteries (NOT APC). Normally Amazon hasn't had a problem like this for all the items I've ordered when they list either Amazon or the supplier. I started the first step which is sending a note the seller, not holding my breath they are going to make this right. I'm sure Amazon will give me my money in the end, but this doesn't help me now as old batteries are dieing which is why I ordered the replacement. I could order the better separate batteries which are less money from another company as now Amazon has a higher price for the same APC pack. Last time I order off of Amazon for the APC pack I got a good and price and had no problems. So watch who is shipping your battery pack and double or triple check to be sure you are getting the real deal.

What I would really like is for Amazon to give me a return label for these batteries and ship me the real APC batteries!

This item does not fit the 'xs-1500'.

It fits the xs series only up to 'xs-1000', and certain other series' up to 1500. To top it off, Amazon does not allow returns on hazardous items.

You can fit it to the xs-1000 by:
1 cutting the tape/seal both sides, above & below adapter plate.
2 dis-assembling from wiring harness.
3 place batteries side-by-side, orient to match old batteries.
4 use jumper from old batteries to connect in series (+of one battery to -of other).
5 connect black cable to '-'
6 slide into the UPS, connecting red cable to '+' terminal when it reaches.

So, if you read the model number off of the actual UPS unit, which in my case says "Back UPS XS 1500".

Be careful when using this as the actual model, because that will lead you to buying the RBC33. Better to open up your PowerChute application, click on Technical Data and note the "real" model, which in my case was "Back-UPS BX1500G". Using that would get you to the RBC124 which is correct.

Cannot return the battery (hazardous material)...what to do?

Simple...get yourself a utility knife, duct tape (or similar heavy duty tape). Take your old battery out and set it next to your new one. Then...

1. Cut the tape holding the two batteries together on the old one
2. Do the same for the new one
3. Gently pull the two batteries apart for each
4. Old battery first - disconnect the wires from the terminals on each of the two batteries being careful to keep the orientation of the middle plastic separator the same (helps get it right when moving to the new one)
5. Disconnect wires from terminals on each of the new battery (discard those wires and plastic separator
6. Place the old separator in between the 2 halves of the new battery
7. Connect the Red(Positive) to the Red connector and the Black (Negative) to the Black connector on one half
8. Repeat for the other half
9. While pressing the two halves together with the middle piece of the old battery in between, tape together where the halves meet. Make sure the batteries are lined up and there is no gap in the middle. It does not have to be perfect, just close.
10. To make removal easier next time, unstick the tabs from each of the older batteries and restick them in the same spot on the new one.
11. Gently drop in the new battery with the connector facing down, replace cover - you are good to go
12. Note to self - buy the right one next time :-)
