PRODUCT DESCRIPTION
APC Replacement Battery Cartridge #143, 120V 5Ah Lead-Acid Battery (APCRBC143) - 2 Years Local Warranty
Genuine APC Replacement Battery Cartridge #143
The APC Replacement Battery Cartridge #143 (APCRBC143) is Schneider Electric's own 120 V DC replacement cartridge, rated at 5 Ah and built from leak-proof sealed lead-acid cells. It ships as a complete assembly with the connectors already fitted. Buying the genuine APC part keeps the charging profile, the runtime calculation and the warranty position on your UPS exactly as the manufacturer intended, which a generic pack of nominally similar cells does not.
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 does not publish an operating temperature range for this particular part number, but the physics is the same across the range: a cartridge in an air-conditioned rack will outlast the same cartridge in a hot riser. 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.
Confirm the Fit Before You Order
This is the one cartridge in the APC range where we will not publish a compatibility table. Schneider no longer publishes a model list for APCRBC143 on any page we can cite — its own compatibility widget returns a count of matching products without naming them, and the model lists circulating on marketplace listings contradict each other on whether this part serves the low-voltage or the high-voltage Smart-UPS X builds. Rather than print a list that could send you the wrong 120 V battery, we would rather you sent us the model number from the rear label of your UPS, or checked it on Schneider's own selector tool linked below. We will confirm in writing before anything ships.
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
Schneider does not publish a compatible-model list for this cartridge. That is an unusual thing for a product page to say, so here is exactly what we found. The compatibility panel on Schneider's own APCRBC143 record renders a count of matching products — one external battery pack and four UPS models — without naming any of them. The model lists that circulate on marketplace listings split between the low-voltage and the high-voltage Smart-UPS X builds and cannot both be right. No Schneider document we could retrieve names a single UPS model for this part.
What we can tell you is what the cartridge is: a 120 V DC, 5 Ah lead-acid assembly. That places it with the 120 V battery bus used by the larger Smart-UPS X units and their external battery packs rather than the 48 V bus of the smaller models. If you are working on an SMX120BP or an SMX120RMBP2U pack, note that Schneider does not publish a cartridge part number on those records either — it is a question we are putting to the distributor, and we will answer it in writing for your specific unit.
How to confirm the fit. Read the model number from the label on the rear or side of the UPS and check it against Schneider's APC UPS Replacement Battery Cartridge Selector Tool, which selects by UPS model rather than by battery part number. Or send the model number to us and we will confirm it for you. If your UPS is a 2200 or 3000 VA Smart-UPS X rack model, the cartridge Schneider does name is APCRBC117.
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.

Ordering notes. Quote the part number APCRBC143 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 #143 (APCRBC143)
Which APC UPS models does the APCRBC143 fit?
We do not publish a list, because Schneider does not publish one. Its own compatibility panel for this part returns a count of matching products without naming them, and the lists circulating elsewhere contradict each other. The cartridge is a 120 V DC, 5 Ah assembly, which places it with the 120 V battery bus rather than the 48 V one. Send us the model number from the rear label of your UPS, or use Schneider's selector tool linked in the downloads section, and we will confirm the correct part in writing before anything ships.
Why is there no weight or dimension figure on this page?
Because we could not verify one against a Schneider source. Every other cartridge we list carries published figures taken from Schneider's own documentation; for this part number the only figures we found came from a single reseller mirror, and a 120 V lead-acid cartridge is much too heavy an item to guess at. Ask us before you arrange a courier and we will confirm the shipping weight with the distributor.
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 does not publish a service-life figure against this particular part number. Its general guidance for sealed lead-acid replacement cartridges is three to five years, and in Singapore the climate is the deciding factor: 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. Replace on age and on the UPS's own battery-fault warning rather than waiting for an outage to test it.
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 #143 (APCRBC143) sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the APCRBC143 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.
