APC Replacement Battery Cartridge #43
PRODUCT DESCRIPTION
APC Replacement Battery Cartridge #43 for Smart-UPS Line Interactive, 48V 10Ah Lead-Acid Battery (RBC43) - 2 Years Local Warranty
Genuine APC Replacement Battery Cartridge #43
The APC Replacement Battery Cartridge #43 (RBC43) is the manufacturer's own replacement pack for the SMT2200RMI2UC and SMT3000RMI2UC, and for the other APC units that specify this cartridge number. It arrives as a complete sealed lead-acid assembly with the correct connectors already fitted and, where the design calls for one, the metal battery tray, rated by Schneider Electric at 48 V DC, 10 Ah. Fitting the genuine cartridge returns the unit to its designed backup capacity, and it keeps the question of whether a third-party pack affects your UPS warranty cover off the table entirely.
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.
Exact-Fit Cartridge for the SMT2200RMI2UC and SMT3000RMI2UC
APC cartridge selection follows the chassis, not the VA rating: two Smart-UPS units of identical capacity in tower and rack form take different cartridges, and a SmartConnect build often differs from the standard build of the same model. This part is the one Schneider names for the model shown above. Read the part number from the label on the rear of the UPS rather than working from the capacity alone, and send it to us if you would like it checked before you order.
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 together with the matching UPS, rack PDU or network management card on a single purchase order. We can also arrange 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
UPS models this cartridge is specified for. This is confirmed from the Schneider product data sheets for the SMT2200RMI2UC and SMT3000RMI2UC, both of which name RBC43 as their replacement battery.
| SMT2200RMI2UC | APC Smart-UPS 2200VA LCD RM 2U 230V with SmartConnect |
| SMT3000RMI2UC | APC Smart-UPS 3000VA LCD RM 2U 230V with SmartConnect |
RBC43 is the long-running 2U rack cartridge for this capacity band and is also listed for the legacy SUA2200RM2U, SUA2200RMI2U, SUA3000RM2U, SUA3000RMI2U and SUA3000RMT2U Smart-UPS units and for the SUM1500RMXL2U, SUM1500RMXLI2U, SUM3000RMXL2U, SUM3000RMXLI2U and SUM48RMXLBP2U Smart-UPS RM XL models. It is a rack cartridge throughout — the matching tower models take a different part. Send us the model number from the rear label and we will confirm before you order.
Electrical fit. Schneider rates this cartridge at 48 V DC, 10 Ah. A UPS will only accept the cartridge built for it: the charger, the runtime calculation and the low-battery cut-off are all set for a specific pack, so a cartridge of the wrong voltage or capacity will either be rejected, mis-report runtime, or shorten its own life on the wrong charge profile.
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.

Matching UPS Models
If you are replacing the UPS rather than the battery, or adding a second unit, these are the models this cartridge is specified for:
| SMT2200RMI2UC | APC Smart-UPS 2200VA LCD RM 2U 230V with SmartConnect |
| SMT3000RMI2UC | APC Smart-UPS 3000VA LCD RM 2U 230V with SmartConnect |
Ordering notes. Quote the part number RBC43 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: check the net weight in the specifications above before arranging a courier, because several cartridges in this range are considerably heavier than they look. 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.
Datasheet & Downloads
- Schneider Electric product page for RBC43 — official product identity, environmental data and document library
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 #43 (RBC43)
Which APC UPS models does the RBC43 fit?
Schneider specifies it for the SMT2200RMI2UC and SMT3000RMI2UC. This is confirmed from the Schneider product data sheets for the SMT2200RMI2UC and SMT3000RMI2UC, both of which name RBC43 as their replacement battery. Selection follows the UPS part number rather than its VA rating, because tower and rack builds of the same capacity take different cartridges. If your model is not named here, send us the part number from the rear label and we will confirm the correct cartridge in writing before you order.
What voltage and capacity is the RBC43?
Schneider rates it at 48 V DC, 10 Ah. That is the cartridge-level rating, not the rating of one battery block inside it — a distinction worth watching, because several listings elsewhere quote the block figure and make the pack look half its actual size.
Can I fit the cartridge myself, and can it be done without shutting the UPS down?
The cartridge ships fully assembled with its connectors already fitted, so mechanically 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 3 to 5 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 unit in an air-conditioned rack will comfortably reach the top of that range while one in a hot riser or an unventilated cabinet may not. Schneider rates the cartridge for operation up to the temperature shown in the specifications above; running near that ceiling is exactly what shortens battery life.
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 a battery recycling guide with the cartridge, and SourceIT can arrange collection of the exhausted pack for proper recycling when the replacement is delivered — tell us when you order so it is scheduled with the delivery.
Is this a genuine APC part, and what does the warranty cover?
Yes. Every APC Replacement Battery Cartridge #43 (RBC43) sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the RBC43 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.
