APC Replacement Battery Cartridge #118
PRODUCT DESCRIPTION
APC Replacement Battery Cartridge #118 (APCRBC118) - 2 Years Local Warranty
The 120 V Cartridge for the Smart-UPS X External Battery Pack
The APCRBC118 is the genuine APC replacement battery tray for the Smart-UPS X external battery pack — not for the Smart-UPS X unit itself. That distinction is the single most useful thing on this page, because the cartridge that goes inside the UPS and the cartridge that goes inside its extended-runtime pack are electrically identical and mechanically different, and they are routinely confused. Schneider Electric's own marketplace listing for the SMX120RMBP2U names APCRBC118 as its replacement battery, two cartridges per pack.
A Real 120 V Cartridge, Not a 12 V One
Schneider's product page markets this part as "12V 5.0AH". Its product data sheet states 120 V, ten battery blocks per string, and the net weight of 22.27 kg confirms it: ten blocks, not one. The 12 V figure is the rating of a single block inside the tray. The pack it serves, the SMX120RMBP2U, independently publishes a 120 V battery voltage and ten blocks per string. We publish the cartridge figure, because that is the one that matters when you are checking what you are about to install.
Extended Runtime for Singapore Server Rooms
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.
Smart-UPS X external battery packs exist to carry a load through the length of a real outage rather than a clean shutdown, which is exactly the case for a comms cabinet feeding site access control, CCTV or a small virtualisation host. That value evaporates the moment the pack's own batteries age out — the UPS will still transfer, but the extended runtime you paid for is no longer there. Replacing the pack's cartridges restores it.
A Two-Person Item
At 22.27 kg net and 584 mm deep, this is one of the heavier cartridges in the APC range and a genuine two-person lift at rack height. A Smart-UPS X external battery pack takes two of them, so budget for roughly 45 kg of battery when you plan the job and the delivery. Supplied on a GST invoice with local Singapore warranty.

Compatibility & Runtime
Confirmed fitment.
- SMX120RMBP2U — APC Smart-UPS X external battery pack, rack/tower 2U, 120 V DC, with rail kit. Schneider Electric's marketplace listing for this pack names APCRBC118 as its replacement battery and states two cartridges per pack. This is the strongest possible source: official, and read in the UPS-to-cartridge direction.
- Smart-UPS X-Series 2000-3000 VA external battery packs generally — Schneider's installation guide for the Smart-UPS X 2000-3000 VA range covers cartridges 117 and 118 together, and identifies 118 as the external-battery-pack cartridge.
The 117 / 118 split, drawn the way Schneider draws it. APCRBC117 is the cartridge for the Smart-UPS X 2200 VA and 3000 VA UPS itself. APCRBC118 is the cartridge for the external battery pack that extends it. Both are 120 V ten-block trays with the same electrical rating; the trays are not the same and the two are not interchangeable. If you are replacing the batteries inside an SMX2200RMHV2U or SMX3000RMHV2U you want APCRBC117, not this part.
An unresolved point worth knowing before you order. Schneider's marketplace names APCRBC118 for the 2U rackmount pack SMX120RMBP2U, but names APCRBC143 for the 4U rack/tower pack SMX120BP — even though both packs publish the same 120 V, the same ten blocks per string and the same two cartridges each. We have not been able to resolve which of the two cartridges Schneider intends for which pack, or whether one supersedes the other, and we are not going to guess. If your pack is the SMX120BP rather than the SMX120RMBP2U, send us the serial number and we will confirm the part with the distributor before you order.
Can I change it myself? The APCRBC118 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.

Frequently Asked Questions — APCRBC118
Is the APCRBC118 a 12 V cartridge or a 120 V cartridge?
120 V. Schneider's product page markets it as "12V 5.0AH", which is the rating of one battery block inside the tray; Schneider's own product data sheet for the same part states 120 V with ten blocks per string, and the 22.27 kg net weight confirms ten blocks rather than one. The pack it goes into publishes a 120 V battery bus. Treat the 12 V figure as a per-block number and ignore it when ordering.
What is the difference between APCRBC117 and APCRBC118?
APCRBC117 goes inside the Smart-UPS X 2200 VA or 3000 VA UPS. APCRBC118 goes inside the external battery pack that extends its runtime. They carry the same electrical rating and different trays, so they are not interchangeable. Schneider's installation guide for the Smart-UPS X 2000-3000 VA range covers both and draws the line exactly that way.
How many cartridges does one external battery pack take?
Two. Schneider's record for the SMX120RMBP2U states a replacement battery quantity of two. Replace both at the same time and with cartridges of the same age — mixing a new tray with an aged one in the same pack shortens the life of the new one.
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 APCRBC118, 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.
Can one person carry it?
Not comfortably. Net weight is 22.27 kg with a 584 mm tray depth, and a full pack takes two of them. Plan a two-person lift and clear floor space beside the rack before you start.
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 APCRBC118 cartridge sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the APCRBC118 with a 2-year manufacturer warranty.
