APC Replacement Battery Cartridge #161
PRODUCT DESCRIPTION
APC Replacement Battery Cartridge #161 (APCRBC161) - 2 Years Local Warranty
The 24 V Cartridge for the Back-UPS Pro BR1200SI
The APCRBC161 is APC's factory replacement battery tray for the Back-UPS Pro BR1200SI, the 230 V 1200 VA tower we sell for Singapore desks and small server cupboards. Schneider Electric's own Back-UPS replacement-battery reference for the 230 V market names the pairing directly, which makes this one of the few Back-UPS cartridges with a confirmed local host rather than a North American one.
24 V, 9 Ah — Confirmed, Not Inferred
Schneider's product data sheet for this cartridge states a nominal 24 V and 9 Ah outright, and its official product name carries the same figures. The 5.13 kg net weight is exactly two 12 V 9 Ah blocks in series, so for once the marketed rating, the data sheet and the physics all agree. That makes the APCRBC161 the reference point for its whole enclosure family — several neighbouring cartridges share this tray and publish a misleading per-block figure instead.
Back-UPS Pro Batteries in a Singapore Climate
Singapore runs a 230 V / 50 Hz supply that is among the most reliable in the region, but the PUB grid still sees voltage dips during the monsoon storm season, and year-round humidity of 80% and above is hard on sealed lead-acid chemistry. A UPS battery in a Singapore comms cabinet or server room commonly reaches the end of its useful life sooner than the same battery would in a temperate climate, which is why a scheduled cartridge replacement matters more here than the calendar alone suggests.
A Back-UPS or Back-UPS Pro in a Singapore home office, retail counter or reception desk usually sits in ambient room air rather than a cooled cabinet, and it spends nearly all its life on float charge waiting for an event that may come twice a year. That combination — warm, humid, rarely cycled — is precisely the one that ages sealed lead-acid quietly, so the first sign of trouble is often the UPS failing its self-test rather than any change you would notice day to day.
Assembled and Ready to Fit
The cartridge arrives complete, with its two blocks and internal link made up and its connectors fitted, so the exchange is a slide-out, slide-in operation. Supplied on a GST invoice with local Singapore warranty.

Compatibility & Runtime
Confirmed fitment for the 230 V market — the one that matters in Singapore.
- BR1200SI — APC Back-UPS Pro 1200 VA, 720 W, tower, 230 V. Named in Schneider Electric's Back-UPS replacement-battery reference for Europe and the 230 V market, as a user-replaceable battery.
Also confirmed, for 120 V equipment. Schneider's reference for the USA and Canada additionally names the BN1500M2, BN1500M2-CA and BR1350MS. These are not sold in Singapore, but they are listed here because installed-base equipment does travel.
What we will not tell you. Reseller lists for this part commonly add the BP1050, BR1350MS-TW and BR1500M2-LM. Not one is supported by a Schneider document we could verify, so none appears here.
This tray is shared — the part number is the only reliable identifier. The APCRBC160, 161, 162 and 163 all use the same 302 x 66 x 109 mm enclosure and the same carton. They differ only in the cells inside and therefore in weight. Measuring the old cartridge will not tell you which one you have; read the label.
A correction to what this page used to say. The previous copy gave 12 V, 7.2 Ah and approximately 2.7 kg. The correct figures are 24 V, 9 Ah and 5.13 kg — the old weight was understated by nearly half.
Can I change it myself? The APCRBC161 ships fully assembled with its connectors fitted, so the physical exchange is a slide-out, slide-in operation and no tools are needed. Schneider Electric does not publish a statement for this part about whether it may be changed while the equipment is energised, so we do not make that claim. The installation guide packed in the box is the authority on whether the unit must be shut down first — read it before you start, and if you would rather not do it yourself we can arrange for it to be done.

A word on weight. APC replacement battery cartridges range from about 2.5 kg for a single-block Back-UPS part to over 30 kg for a large Smart-UPS On-Line tray. The net weight in the specification table above is the figure to use when you plan handling, lift assistance and courier booking. A great many published weights for these parts, in reseller catalogues and in APC's own syndicated feed data, are badly out and usually far too low. Treat a weight you find elsewhere with suspicion, and if you need a certified figure for freight or for a lifting assessment, ask us.

Why there are no direct PDF links here. Schneider Electric's public download host redirects between domains and has repeatedly returned a different cartridge's document than the one requested. Rather than publish a link that may hand you the wrong specification, we link the Schneider landing pages above, which are stable and always resolve to the correct document. If you need the PDF itself for a tender, a service contract or an audit file, email sales@sourceit.com.sg and we will send the current revision for your exact part number.
Frequently Asked Questions — APCRBC161
I have a Back-UPS Pro BR1200SI. Is this the right cartridge?
Yes. Schneider Electric's Back-UPS replacement-battery reference for the 230 V market names the APCRBC161 for the BR1200SI as a user-replaceable battery. That is the strongest kind of confirmation available for a cartridge, and it applies to the exact 230 V model sold here rather than a North American equivalent.
Is the 24 V figure confirmed, or worked out?
Confirmed. Schneider's product data sheet for this cartridge states 24 V and 9 Ah as specification rows, and its official product name carries the same figures. The 5.13 kg net weight is exactly two 12 V 9 Ah blocks. This is one of the few cartridges in the range where everything Schneider publishes agrees.
How do I know this is the right cartridge for my UPS?
Match the part number, not the shape. Several APC cartridges share an identical tray and identical external dimensions while carrying different cells, different voltages and different retention hardware, so measuring the old one tells you very little. Open the UPS battery compartment and read the label on the cartridge you are removing, or check your UPS model's documentation for the APC replacement battery part number it names. If the part number on your old cartridge reads APCRBC161, this is the one. If you are unsure, send us your UPS model and serial number and we will confirm it in writing before you order.
How is it different from the APCRBC160, 162 and 163?
Only in the cells. All four use the same 302 x 66 x 109 mm enclosure and the same carton. The 162 is 6.5 Ah at 4.04 kg, the 160 is 7.2 Ah at 4.45 kg, this one is 9 Ah at 5.13 kg and the 163 is 9.4 Ah at 5.85 kg. They are not interchangeable and they cannot be told apart by measuring — go by the part number on the label.
Can I fit the higher-capacity APCRBC163 instead to get more runtime?
No. The cartridge is matched to the UPS charger, and fitting a part your UPS does not specify risks the unit and the warranty even where it physically slots in. If you need more runtime than the BR1200SI provides, the answer is a larger UPS rather than a larger cartridge — we can size one against your actual load.
How long will the new cartridge last?
APC does not publish a service-life figure for every cartridge, and where it does the figure is a range rather than a promise, because sealed lead-acid life is driven by ambient temperature and by how often the battery is actually discharged. As a working rule for Singapore, a cartridge in an air-conditioned server room will outlast one in a warm riser or an unconditioned comms cabinet, and every sustained rise in operating temperature shortens the life meaningfully. Plan a replacement cycle rather than waiting for the UPS to report a failed battery during an outage.
What do I do with the old cartridge?
Sealed lead-acid batteries must not go into general waste in Singapore. The cartridge is recyclable through the licensed waste-handling channels, and the box your replacement arrives in is designed to take the exhausted unit back out. Tell us when you order and we can arrange collection of the old cartridge with the delivery of the new one.
Does it come with a Singapore warranty and a GST invoice?
Yes. Every APCRBC161 cartridge sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the APCRBC161 with a 2-year manufacturer warranty.
