APC Replacement Battery Cartridge #22

General

Battery Specifications

Physical & Environmental

Do not read the per-block figure as the cartridge rating. Schneider's product page reads "12V 7.0AH" and its data sheet's battery-voltage field reads 24 V. The second is the cartridge. This is the only member of its tray family for which Schneider fills that field in, which is why this part is the reference point for the others. 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.

What the RBC22 fits

From Schneider's own installation guide, document SPD_ASTE-6Z8LGE_EN, whose catalogue title is "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

An important limitation, stated plainly: the guide covers four cartridges against four UPS models and does not say which cartridge goes with which UPS. Since the RBC22 is the 24 V, 7 Ah member and the smallest of the four, it is the one that belongs to the 700 to 750 VA end of the family, and APC's own retail listings name the RBC23 against the 1000 VA units and the RBC24 against the 1400 VA ones. That is a reasoned split, not a Schneider statement, so confirm your model with us before ordering.

230 V hosts for Singapore

The models Schneider names in the guide are 120 V and 100 V builds. The 230 V siblings of the same chassis do exist and are the realistic Singapore installed base:

• SU700RMI2U — APC Smart-UPS 700VA RM 2U 230V. Catalogued by Schneider; not named against this cartridge in a Schneider document.
• SUA750RMI2U — APC Smart-UPS 750 VA USB RM 2U 230 V, discontinued March 2023 and superseded by the SMT750RMI2UC. A proven distributor names the RBC22 for it; Schneider's own page says only that a replacement battery is available without naming it.

We present both as likely rather than confirmed. Send us the model number and we will put it to the distributor.

One model the RBC22 does NOT fit

Some distributor listings claim the RBC22 fits the SMT750RMI2U. It does not. Schneider's data sheet for the SmartConnect generation of that unit names APCRBC123 as its replacement battery. The SMT 750 VA 2U generation is an APCRBC123 host, and fitting an RBC22 there is a wasted order.

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.

The RBC22's own 5 kg is the lightest of the group and is the one figure that does distinguish it — but only if you have accurate scales and know what you are comparing against. RBC23 is 10 kg and RBC24 is 11.96 kg in the same case. Order by part number.

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, and runtime falls steeply as load rises. If you need materially longer, that is a UPS decision rather than a battery one.

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.

The 2U Smart-UPS rack cartridge family at SourceIT

• RBC22 (this listing) — 24 V, 7.0 Ah, 5 kg. Two blocks. The smallest of the family.
• RBC23 — 10 kg, four blocks, same tray.
• RBC24 — 11.96 kg, four blocks, same tray.
• RBC25 — 10.36 kg, four blocks, a different and wider tray.
• RBC43 — 48 V, 10 Ah, a 2U Smart-UPS rack tray.
• APCRBC123 — 24 V, 7.0 Ah, for the SmartConnect 2U generation. Note the SMT750RMI2U takes this, not the RBC22.
• RBC18 — 12 V, 9 Ah, for the 1U Smart-UPS SC and PowerStack units.

Send the model number from your UPS to sales@sourceit.com.sg and we will match it against Schneider's documentation before you order.

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.

Is the RBC22 12 V or 24 V?
24 V. Schneider states it in the battery-voltage field of its own product data sheet, and the 5 kg net weight confirms it as two 12 V 7 Ah blocks. The "12V 7.0AH" on Schneider's product page is the per-block rating. Publishing 12 V for this cartridge is a factual error and a common cause of returns.

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. As the 24 V 7 Ah member it belongs at the 700 to 750 VA end. For Singapore the realistic hosts are the 230 V siblings, SU700RMI2U and SUA750RMI2U, which we present as likely rather than confirmed. Send us your model number.

Does it fit the SMT750RMI2U?
No, despite what some listings say. Schneider's data sheet for the SmartConnect build of that unit names the APCRBC123 as its replacement battery. The SMT 750 VA 2U generation is an APCRBC123 host.

Can I change it without shutting the UPS down?
Yes, and unusually for this range Schneider says so directly. The installation guide covering the RBC22, RBC23, RBC24 and RBC24J states that you may leave the UPS and the protected equipment on for the procedure, and describes the tray as hot-swappable. The caveat is Schneider's own: while the battery is disconnected there is no backup, so do not do it during unstable supply.

How do I tell an RBC22 from an RBC23 or RBC24?
By the part number on the label, and realistically by nothing else. 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 respectively — and that only helps if you have scales and know what you are comparing against.

How long should it last?
Schneider publishes no expected service life for this part, so we will not quote one. Sustained heat is the main factor and Singapore supplies it, so a unit in a warm comms cabinet will need replacing sooner than one in a conditioned room. Test the UPS rather than assume.

Does it come with a local Singapore warranty?
Yes. Every APC RBC22 sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the RBC22 with a 2-year manufacturer warranty.
