PRODUCT DESCRIPTION

APC Replacement Battery Cartridge #23 (RBC23) - 2 Years Local Warranty

RBC23 Datasheet: a Four-Block 2U Smart-UPS Rack Cartridge

The RBC23 is the genuine APC replacement battery cartridge for the middle of the 2U rackmount Smart-UPS family. Schneider covers it in a dedicated installation guide alongside the RBC22, RBC24 and RBC24J, titled for "Smart-UPS 2 U, 700 VA, 1000 VA, 1400 VA", and APC's own retail listings name it against the SUA1000RM2U.

It shares its 83 x 216 x 343 mm carrier with the RBC22 but weighs exactly twice as much — 10 kg against 5 kg — which is the clearest signal available that it holds four blocks where the RBC22 holds two.

Why This Listing Does Not State a Cartridge Voltage

We could put a number here. We would rather explain why we have not.

Schneider's published net weight tells us this tray holds four 12 V blocks. What it does not tell us is how they are wired. Four blocks can sit as four in series, giving 48 V at the block capacity, or as two parallel pairs, giving 24 V at double the capacity. Schneider's data-sheet template does have a battery-voltage field — it is filled in as 24 V on the sibling RBC22 — but on this part it is left empty, and nothing else Schneider publishes distinguishes the two arrangements from outside the tray.

Publishing the wrong voltage on a battery is the worst class of error on a product page — it sends people to the wrong part and it puts equipment at risk. So this listing gives you Schneider's per-block figure, the confirmed physical facts, and the honest statement that the assembled voltage is not published. Match this cartridge to your UPS by part number, and if you need the system voltage for a design, ask us and we will put it to the distributor.

Ten Kilograms in a 2U Comms Cabinet

At 10 kg net and 10.91 kg shipping, this is a two-hand lift into a rack rather than a casual one, and the cartridge slides in at the front of a running UPS. Give yourself room in front of the cabinet before you start rather than balancing it on a cable tray.

Singapore is hard on lead-acid batteries. Ambient temperature sits near the top of the useful band all year, and every few degrees of sustained heat shortens a sealed lead-acid battery's service life measurably. A comms cabinet or riser room that runs warm will age a cartridge faster than an air-conditioned server room will. Plan replacement on the calendar instead of waiting for the UPS to fail its self-test, and keep the unit out of direct sun and clear of the warm-air discharge from whatever it is protecting.

Genuine APC Supply, GST-Invoiced, from Singapore Stock

SourceIT supplies the RBC23 as genuine APC by Schneider Electric stock, sold in Singapore with a GST invoice and local warranty support. We hold this part on the shelf instead of ordering it in, so a failed UPS does not have to wait on a shipment. If you are not certain which cartridge your unit takes, send us the model number printed on the UPS rear panel and we will confirm it against Schneider's documentation before you buy.

Schneider Electric does not publish a UL listing or a CE marking for this cartridge, and we do not claim either. What Schneider does publish is a REACh declaration and a RoHS position, and those are reproduced in the specification table exactly as written.

The blank voltage row, in short. Schneider's data-sheet template does carry a battery-voltage field, and on the sibling RBC22 it is filled in as 24 V. On the RBC23 it is left empty. The 10 kg net weight against the RBC22's 5 kg in an identical tray establishes four blocks rather than two, but four blocks can be wired as 48 V in series or as 24 V in two parallel pairs, and nothing Schneider publishes distinguishes the two. Match the cartridge by part number against your UPS, never by comparing voltage or physical size. The reasoning is set out in full further up the page.

The 0 to 45 °C operating range is as Schneider prints it, and it differs from the 0 to 40 °C published for the RBC22 and RBC24 in the same tray. We reproduce it as printed. Schneider publishes no charge time for a replacement cartridge. Recharge time is a property of the UPS that charges it, not of the battery tray, so look it up on your UPS model, not here.

Compatibility & Runtime

What the RBC23 fits

From Schneider's own installation guide, document SPD_ASTE-6Z8LGE_EN, catalogued as "Replacement Batteries: Smart-UPS 2 U, 700 VA, 1000 VA, 1400 VA". The guide covers the RBC22, RBC23, RBC24 and RBC24J against these hosts:

SU700RM2U — 120 V
SU1000RM2U — 120 V
SU1400RM2U — 120 V
SU1400RMJ2U — 100 V, Japan

The guide does not split the four cartridges across the four UPS models. APC's own retail listings name the RBC23 for the SUA1000RM2U, which puts it at the 1000 VA end of the family, and that is consistent with it holding twice the blocks of the 700 VA class RBC22. We present that as a reasoned reading rather than a Schneider statement.

230 V hosts for Singapore

Schneider's named models are 120 V and 100 V builds. The same 2U chassis was sold in 230 V "I"-suffix form — SU700RMI2U and SUA750RMI2U are both catalogued by Schneider — and those are the realistic Singapore installed base. No Schneider document ties them to a specific cartridge in this group, so send us your model number and we will confirm with the distributor rather than have you order on an assumption.

Several APC cartridges share this exact tray. Only the part number tells them apart.

Schneider publishes the same 83 x 216 x 343 mm case and the same 152 x 368 x 495 mm carton across cartridges of genuinely different capacity, and it reuses the same net weights too: 10.00 kg appears on more than one part in this case, and so does 11.96 kg. Measuring a cartridge, weighing it, or comparing it against a photograph cannot reliably tell you which one you are holding.

In this tray, RBC22 is 5 kg, the RBC23 is 10 kg and RBC24 is 11.96 kg. Schneider also publishes the same 83 x 216 x 343 mm case for several current-generation APCRBC cartridges, including some at exactly 10.00 kg, so the scale will not always settle it either. Read the label on the cartridge you are removing.

Changing the cartridge

This is one of the few APC cartridges where Schneider states the answer directly. The installation guide that covers the RBC22, RBC23, RBC24 and RBC24J says in its own words: "You may leave the UPS and the protected equipment on for the following procedure", and describes the design as an easy to replace hot-swappable battery tray, adding that battery replacement is a safe procedure isolated from electrical hazards. Schneider's general Smart-UPS hot-swap FAQ says the same for the range.

The caveat Schneider attaches is worth carrying over rather than burying: while the battery is disconnected, the UPS has no backup available. If the supply is unstable — a storm afternoon, or works in the building — wait. The guide in the box remains the authority on the procedure for your unit.

Runtime

A fresh cartridge restores the runtime the UPS was rated for at your load; it does not extend it. Runtime falls steeply as load rises, so measure the actual load rather than working from the UPS nameplate.

Sealed lead-acid cartridges must not go into general waste in Singapore. Bring the exhausted cartridge back to us with the replacement and we can arrange collection through a licensed recycler, or dispose of it through your own NEA-licensed collector.

Datasheet & Downloads

Every link below is a Schneider Electric page we have opened and confirmed resolves.

We deliberately do not publish direct PDF links for this part. Schneider's file-download host redirects across domains and has repeatedly returned a different model's document than the one requested, so a direct link is not safe to rely on. Every link above is a Schneider Electric landing page that we have opened and checked. If you would like the PDF itself, email sales@sourceit.com.sg with your UPS model and we will send the current revision together with a GST-invoiced quotation.

Frequently Asked Questions — APC RBC23

What voltage is the RBC23?
Schneider does not publish one for the assembled cartridge, and we will not invent it. What is established is that the tray holds four 12 V blocks — its 10 kg weight is exactly double that of the two-block RBC22 in an identical case. Four blocks can be wired as 48 V in series or 24 V in two parallel pairs, and Schneider leaves the field that would tell us apart empty on this part. Match it by part number, not by voltage.

Which UPS models does it fit?
Schneider's installation guide covers the 2U rackmount Smart-UPS 700, 1000 and 1400 VA family: SU700RM2U, SU1000RM2U, SU1400RM2U and SU1400RMJ2U. APC's own retail listings name the RBC23 for the SUA1000RM2U specifically. The 230 V siblings of that chassis, SU700RMI2U and SUA750RMI2U, are the realistic Singapore hosts but are not named against a specific cartridge by Schneider. Send us your model number.

How do I tell it apart from an RBC22 or RBC24?
By the label. All three share the same 83 x 216 x 343 mm case and the same carton. Weight is the only physical difference — 5 kg, 10 kg and 11.96 kg — and several current-generation APCRBC cartridges use the same case at similar weights, so even scales will not always settle it.

Can I change it with the UPS running?
Yes. Schneider's installation guide covering the RBC22, RBC23, RBC24 and RBC24J states you may leave the UPS and the protected equipment on for the procedure and describes the tray as hot-swappable. Its caveat applies: while the battery is disconnected the UPS has no backup, so choose a settled moment rather than a storm afternoon.

Why is the operating temperature 45 degrees when the RBC22 says 40?
Because that is what Schneider prints for each part, and we reproduce published figures rather than harmonise them. It is a small inconsistency in Schneider's own data across a family that shares a tray. In practice, neither figure is a target — sustained heat shortens sealed lead-acid life well before you reach either number.

How long should it last?
Schneider publishes no expected service life for this part. In Singapore, position matters more than the calendar: a 2U unit at the bottom of a warm cabinet, taking the exhaust of everything above it, will age faster than the same unit in a conditioned room.

Does it come with a local Singapore warranty?
Yes. Every APC RBC23 sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the RBC23 with a 2-year manufacturer warranty.
