APC Replacement Battery Cartridge #105
PRODUCT DESCRIPTION
APC Replacement Battery Cartridge #105 for Smart-UPS XL, 48V Lead-Acid Battery (APCRBC105) - 2 Years Local Warranty
Genuine APC Replacement Battery Cartridge #105
The APC Replacement Battery Cartridge #105 (APCRBC105) is Schneider Electric's own 48 V replacement cartridge for the Smart-UPS XL extended-runtime battery system. Schneider's own installation document for the part is titled "Smart-UPS XL RBC Installation 48 V", and the 24.55 kg net weight tells you the rest: this is a full multi-block tray, 572 mm deep, and a two-person lift. It ships as a complete assembly with the connectors already fitted. Fitting the manufacturer's own cartridge returns the system to its designed backup capacity and keeps any argument about third-party packs and warranty cover off the table.
Why UPS Batteries Need Replacing in Singapore
Sealed lead-acid cells age faster in heat, and a comms cabinet or server room running warm will shorten a cartridge's working life well before its calendar age suggests. Schneider rates this cartridge for operation from 0 to 40 °C at up to 95% relative humidity, so a well-ventilated, air-conditioned rack is doing real work for your battery budget. The failure mode is the dangerous part: a UPS with a tired battery still shows a healthy front panel and still passes mains through, then drops the load the moment a PUB supply dip or a storm-season brownout actually arrives. If your unit has started reporting a battery fault, or has simply been in service for several years, replace the cartridge before you find out the hard way.
A 48V Smart-UPS XL Part, Not a Back-UPS Cartridge
This is one of the APC part numbers most often mis-bought, because Schneider's own marketing text for it reads "12V 9AH replaceable battery" — the rating of a single block inside the tray, not the cartridge. The cartridge is 48 V, it weighs 24.55 kg, and it belongs to the Smart-UPS XL extended-runtime family: Schneider confirms that the SUA48RMXLBP3U external battery pack takes two of them. If you are shopping for a small desk-side Back-UPS battery, this is emphatically not the part — look at the RBC2, RBC17 or APCRBC110 instead.
Local Singapore Stock, GST Invoice and Local Warranty
SourceIT holds APC replacement cartridges in Singapore, so a failed battery does not mean a multi-week import wait on a unit that is currently protecting nothing. Every order ships with a GST invoice for your accounts team and carries local Singapore warranty support, and we can quote the cartridge alongside the matching UPS, rack PDU or network management card on a single purchase order. We can also look at arranging collection of the exhausted cartridge for proper lead-acid recycling when the replacement is delivered — ask for that when you order.

Every figure above is taken from Schneider Electric's own published documentation for this exact part number. Where Schneider does not publish a value, the row says so rather than carrying a figure borrowed from a similar cartridge — APC ratings differ between parts that look identical.
Compatibility & Runtime
What Schneider confirms. The SUA48RMXLBP3U Smart-UPS XL 48 V external battery pack takes two APCRBC105 cartridges. Schneider states that quantity explicitly in the cartridge's own product data sheet and repeats it on its storefront record, and its installation document for the part is titled "Smart-UPS XL RBC Installation 48 V". That is the only fitment Schneider names in a document we can cite.
What we are not going to assert. The Smart-UPS XL host units usually quoted alongside this cartridge — the 2200 and 3000 VA SUA rack models — appear on a single reseller's compatibility list and nowhere in Schneider's own documentation that we could retrieve. They are plausible, and they may well be correct, but one source is not enough for a 24 kg part. Send us the model number from the rear label and we will confirm it with the distributor in writing before anything ships.
Electrical fit. Schneider's storefront record and two of its product data sheets rate this cartridge at 48 V DC. Its marketing description quotes 12 V 9 Ah, which is the rating of one block inside the tray: at 24.55 kg the assembly is plainly a multi-block string, and its installation guide is titled as a 48 V document. A UPS or battery pack will only accept the cartridge built for it.
Runtime after replacement. A new cartridge restores the runtime the UPS was rated for when new; it does not add runtime beyond that. How long that actually is depends entirely on how heavily the UPS is loaded — a unit at a quarter load runs for considerably longer than the same unit near its rated output. Schneider does not publish runtime figures against the cartridge itself, only against the UPS, so if you need a runtime target for a specific rack load, send us the load in watts and the UPS model and we will size it properly rather than quote a number that will not hold.
Installation. The cartridge is supplied fully assembled with its connectors already fitted, so replacement is a slide-out, slide-in operation rather than a wiring job. Schneider does not publish a statement about whether this particular cartridge may be changed with the UPS energised, so follow the installation guide that ships in the box for the correct sequence on your model, and treat the pack as live: these are high-current lead-acid assemblies and a shorted terminal is a genuine hazard. If you would rather not do it in-house, ask us and we will look at arranging it for you.
Package Contents & RBC Ordering Information
In the Box
The cartridge is supplied fully assembled with all required connectors pre-fitted. Schneider does not publish an itemised package contents list for this part number, so we do not invent one.
APC Smart-UPS On-Line and Smart-UPS XL Replacement Cartridges Stocked by SourceIT
| APCRBC105 (this listing) | Smart-UPS XL 48 V external battery pack SUA48RMXLBP3U, which takes two 48 V · 24.55 kg net |
| APCRBC140 | Smart-UPS On-Line SRT and SURT units on a 192 V battery bus 192 V, 5.1 Ah · 34.55 kg net |
Because this cartridge weighs 24.55 kg net and ships at 26.36 kg, it is a palletised or two-person delivery rather than a parcel, and a Smart-UPS XL battery pack takes two of them. Tell us the delivery address and floor when you order and we will arrange it properly.
Ordering notes. Quote the part number APCRBC105 on your purchase order — the cartridge number, not the UPS model, is what determines what ships. This cartridge is a lead-acid assembly and travels as such: net weights across the APC RBC range run from under 3 kg to over 30 kg, so check the physical specifications above before you arrange a courier. We can supply the cartridge on its own, or alongside a network management card, rack PDU or a replacement UPS on a single GST invoice.

Schneider Electric serves its PDF datasheets from a download host that redirects and does not reliably return the document you asked for, so we do not publish direct PDF links here — a link that hands you another model's datasheet is worse than no link at all. If you need the signed product data sheet, the installation guide or a written confirmation of fitment for your unit, email us the UPS model number and we will send the current document across.
Frequently Asked Questions — APC Replacement Battery Cartridge #105 (APCRBC105)
Which APC systems does the APCRBC105 fit?
Schneider confirms one fitment in a document we can cite: the SUA48RMXLBP3U Smart-UPS XL 48 V external battery pack, which takes two of these cartridges. The Smart-UPS XL rack host units are widely quoted alongside it but appear on only one reseller list, so we ask you to send us the model number from the rear label and we will confirm it with the distributor before anything ships.
Why do some listings say this cartridge is 12 V 9 Ah?
Schneider rates the complete cartridge at 48 V DC on its storefront record and in two of its product data sheets. You will see 12 V 9 Ah quoted for this part in some catalogue entries, including Schneider's own marketing metadata: that is the rating of one battery block inside the assembly, not of the cartridge. The net weight settles it — a 12 V block of this capacity weighs roughly 2.5 kg, and this cartridge weighs 24.55 kg, so it is a multi-block assembly. It matters because a charger set for one voltage will not correctly service a pack of another. Schneider's own installation document for this part is titled as a 48 V document, which settles it.
How do I make sure I am ordering the right cartridge?
Read the model number off the label on the rear or side of the UPS and select against that, never against the part number of the battery already inside it and never against the VA rating alone. Schneider says the same thing on its APC UPS Replacement Battery Cartridge Selector Tool: two units of identical capacity in tower and rack form take different cartridges, and a SmartConnect or network-card build often differs from the standard build of the same model. Send us the model number and we will confirm the correct cartridge in writing before you order.
Can I fit the cartridge myself?
Mechanically, yes. The cartridge ships fully assembled with its connectors already fitted, so it is a slide-out, slide-in job that needs no wiring and, on most models, no tools. Whether it can be changed with the UPS still running depends on the model, and Schneider does not publish that statement for this cartridge, so follow the installation guide in the box for the correct sequence rather than assuming either way. Treat the pack as live throughout — it is a high-current lead-acid assembly. If the unit is protecting something you would rather not gamble on, ask us about arranging the replacement.
How long should the cartridge last?
Schneider publishes an expected service life of three to five years for this cartridge. In practice Singapore's climate is the deciding factor: sealed lead-acid cells age markedly faster when they run warm, so a battery pack in an air-conditioned server room will comfortably reach the top of that range while one in a hot riser may not. On an extended-runtime system, replace all the cartridges in a pack together rather than mixing an old block with a new one.
What do I do with the old cartridge?
Do not put it in general waste. A UPS cartridge is a sealed lead-acid assembly and is regulated waste in Singapore. Schneider supplies battery recycling information with the cartridge, and SourceIT can look at arranging collection of the exhausted pack for proper recycling when the replacement is delivered — tell us when you order so it can be scheduled with the delivery.
Is this a genuine APC part, and what does the warranty cover?
Yes. Every APC Replacement Battery Cartridge #105 (APCRBC105) sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the APCRBC105 with a 2-year manufacturer warranty, stated as 2 years repair or replace. Schneider publishes this term worldwide with no regional variation, so the Singapore figure is the same 2 years quoted elsewhere — unlike some APC UPS families, where the European figure is higher and does not apply to a Singapore supply.
