APC Replacement Battery Cartridge #115
PRODUCT DESCRIPTION
APC Replacement Battery Cartridge #115 for Smart-UPS X, 48V Lead-Acid Battery (APCRBC115) - 2 Years Local Warranty
Genuine APC Replacement Battery Cartridge #115
The APC Replacement Battery Cartridge #115 (APCRBC115) is Schneider Electric's own replacement pack for the Smart-UPS X 1500VA 2U rack models, and the cartridge fitted two at a time inside the SMX48RMBP2U external battery pack. It arrives as a complete sealed lead-acid assembly with the correct connectors already fitted, rated by Schneider at 48 V DC across four 9 Ah battery blocks per string. At 10.82 kg it is a substantially bigger assembly than the single-block cartridges used by entry-level Back-UPS units, which is worth knowing before you arrange a courier. 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 Smart-UPS X 1500VA Rack Models
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 network-card build can differ from the standard build of the same model. Within the Smart-UPS X range the cartridge follows the chassis and the battery bus together: the 750 and 1000 VA models take the APCRBC116, the 1500 VA rack models take this cartridge, and the 2200 and 3000 VA models step up from a 48 V string to a 120 V one on the APCRBC117. 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 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
UPS and battery pack models this cartridge is specified for.
| SMX1500RMI2U | APC Smart-UPS X 1500VA Rack/Tower LCD 230V |
| SMX1500RMI2UNC | APC Smart-UPS X 1500VA Rack/Tower LCD 230V with network management card |
| SMX48RMBP2U | APC Smart-UPS X External Battery Pack 48V — each pack takes two APCRBC115 cartridges |
Schneider's own product record names APCRBC115 for the SmartConnect build SMX1500RM2UC, which is a 120 V model not sold in Singapore, and confirms that the SMX48RMBP2U battery pack holds two of these cartridges. The Smart-UPS X operation manual that covers the 230 V range (SMX750I, SMX750INC, SMX1000I, SMX1500RMI2U and SMX1500RMI2UNC) names APCRBC115 and APCRBC116 together without splitting them model by model; the 1500 VA assignment above follows Schneider's 120 V product records and the published reseller compatibility lists, which agree with each other. If your unit is a 750 VA or 1000 VA Smart-UPS X, the cartridge you want is APCRBC116.
Electrical fit. Schneider rates this cartridge at 48 V DC, built from four battery blocks of 9 Ah in series. 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.

Frequently Asked Questions — APC Replacement Battery Cartridge #115 (APCRBC115)
Which APC UPS models does the APCRBC115 fit?
Schneider specifies it for the Smart-UPS X 1500VA 2U rack models — SMX1500RMI2U and SMX1500RMI2UNC in the 230 V range sold here — and it is also the cartridge inside the SMX48RMBP2U external battery pack, which takes two. Selection follows the UPS part number rather than its VA rating. 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 is the APCRBC115?
Schneider rates the complete cartridge at 48 V DC, made up of four 9 Ah battery blocks in series. You will see 12 V 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 10.82 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.
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 #115 (APCRBC115) sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the APCRBC115 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.
