APC Replacement Battery Cartridge #109
PRODUCT DESCRIPTION
APC Replacement Battery Cartridge #109, 24V 9Ah Lead-Acid Battery (APCRBC109) - 2 Years Local Warranty
Genuine APC Replacement Battery Cartridge #109
The APC Replacement Battery Cartridge #109 (APCRBC109) is Schneider Electric's own 24 V replacement cartridge, built from two 9 Ah battery blocks in series and supplied as a complete charcoal-coloured assembly with the connectors already fitted. At 5.58 kg it is roughly twice the mass of the single-block cartridges used by the smallest Back-UPS units, which is the quickest way to tell the two classes apart. Fitting the manufacturer's own cartridge returns the unit 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.
Confirm Your UPS Model Before You Order
Schneider has stopped publishing per-cartridge compatibility lists on the web for this part: its own compatibility panel returns a count of matching products without naming them, and the model lists that circulate on marketplace listings all trace back to a single source. Rather than reprint a list we cannot verify, we would rather you read the model number off the label on the rear of your UPS and checked it against Schneider's own selector tool, linked below, or simply sent it to us. The cartridge itself is fully specified on this page — it is the fitment claim, not the product, that we are being careful about.
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. Its compatibility panel for the APCRBC109 returns a count of matching products without naming them, and the model lists circulating elsewhere all derive from one marketplace listing rather than from independent sources. We are not going to reprint that as though it were verified, because a wrong cartridge on a 24 V unit is a returned part and a UPS left unprotected in the meantime.
What we can tell you with confidence is what the part is: a 24 V DC assembly of two 9 Ah battery blocks in series, 5.58 kg net. That places it with the mid-range Back-UPS units that run a 24 V string rather than the 12 V single-block machines. Note that Schneider's own marketing text for this part quotes "12V 9AH" — that is the rating of one block inside the assembly, not the cartridge rating, and the product data sheet says 24 V.
How to confirm the fit. Read the model number from the label on the rear 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. Schneider's own advice on that page is worth repeating: do not search using the part number of the battery currently in the unit. Or send us the model number and we will confirm in writing before anything ships.
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

Ordering notes. Quote the part number APCRBC109 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.

Frequently Asked Questions — APC Replacement Battery Cartridge #109 (APCRBC109)
Which APC UPS models does the APCRBC109 fit?
We do not publish a list, because Schneider does not publish one that we can verify. The cartridge is a 24 V, 9 Ah, two-block assembly, which places it with the mid-range Back-UPS units running a 24 V battery string. 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 do some listings say this cartridge is 12 V?
Schneider rates the complete cartridge at 24 V DC in its product data sheet, made up of two 9 Ah blocks in series. 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 5.58 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 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. Running near the temperature ceiling shown in the specifications above 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 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 #109 (APCRBC109) sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the APCRBC109 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.
