APC Replacement Battery Cartridge #157
PRODUCT DESCRIPTION
APC Replacement Battery Cartridge #157 for Smart-UPS SmartConnect 2U Rackmount (APCRBC157) - 2 Years Local Warranty
Genuine APC Replacement Battery Cartridge #157
The APC Replacement Battery Cartridge #157 (APCRBC157) is the manufacturer's own replacement pack for the SMC1500I-2UC and SMT1000RMI2UC, and for the other APC units that specify this cartridge number. It arrives as a complete sealed lead-acid assembly with the correct connectors already fitted and, where the design calls for one, the metal battery tray, rated by Schneider Electric at 7.0 Ah per battery block. 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 45 °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 — Check Your Part Number First
This cartridge is specified for the SMC1500I-2UC and SMT1000RMI2UC. Its near-twin, the APCRBC132, is the same physical size and weight but is specified for the SMT1000RMI2U, and Schneider states in writing that the two are not interchangeable: fit the wrong one and it will not secure properly on the battery retention screws. The difference is not the VA rating of the UPS but which build you have, so read the part number from the label on the rear of the unit rather than working from the capacity alone. 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 together with the matching UPS, rack PDU or network management card on a single purchase order. We can also arrange 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 models this cartridge is specified for. This is confirmed from the Schneider product data sheet for the SMC1500I-2UC, and from Schneider FAQ000236099 together with the current SMT1000RMI2UC data sheet, both of which assign APCRBC157 to the SmartConnect build of the SMT1000RM 2U.
| SMC1500I-2UC | APC Smart-UPS C 1500VA LCD RM 2U 230V with SmartConnect |
| SMT1000RMI2UC | APC Smart-UPS 1000VA LCD RM 2U 230V with SmartConnect |
Two points worth knowing. First, Schneider documentation dated 2019 specified APCRBC132 for the SMT1000RMI2UC; current documentation specifies APCRBC157, so an older manual or an out-of-date LCD reading may still name the 132. Second, the 132 and the 157 are the same size and weight but are NOT interchangeable — Schneider states that the wrong cartridge will not secure correctly on the battery retention screws. Check the part number on your unit, or send it to us and we will confirm.
Electrical fit. Schneider does not publish a cartridge-level nominal voltage for this part — see the note in the specification table above. Selection is therefore made by UPS model number rather than by matching a voltage figure, which is how APC intends it to be done in any case. The charger, the runtime calculation and the low-battery cut-off inside the UPS are all set for one specific pack, so the model number is the only reliable way to order.
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.

Matching UPS Models
If you are replacing the UPS rather than the battery, or adding a second unit, these are the models this cartridge is specified for:
| SMC1500I-2UC | APC Smart-UPS C 1500VA LCD RM 2U 230V with SmartConnect |
| SMT1000RMI2UC | APC Smart-UPS 1000VA LCD RM 2U 230V with SmartConnect |
Ordering notes. Quote the part number APCRBC157 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: check the net weight in the specifications above before arranging a courier, because several cartridges in this range are considerably heavier than they look. 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 #157 (APCRBC157)
Which APC UPS models does the APCRBC157 fit?
Schneider specifies it for the SMC1500I-2UC and SMT1000RMI2UC. This is confirmed from the Schneider product data sheet for the SMC1500I-2UC, and from Schneider FAQ000236099 together with the current SMT1000RMI2UC data sheet, both of which assign APCRBC157 to the SmartConnect build of the SMT1000RM 2U. Selection follows the UPS part number rather than its VA rating, because tower and rack builds of the same capacity take different cartridges. 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.
Is the APCRBC157 interchangeable with the APCRBC132?
No. The two cartridges are the same size and the same weight, which is exactly why they get confused, but Schneider states plainly that they are not interchangeable and that the wrong cartridge cannot be properly secured with the battery retention screws. The APCRBC132 is for the SMT1000RMI2U. One further trap: on units running older firmware the UPS display could name the wrong cartridge, and Schneider documentation published in 2019 gave different part numbers from the current documentation. Trust the part number on the unit, or ask us.
Why doesn't this page state a nominal voltage for the cartridge?
Because Schneider does not publish one for this part, and we will not invent it. Schneider publishes a 12 V 7.0 Ah figure against this part, but that describes one battery block: the cartridge is a 216 x 343 mm tray weighing 10 kg. Publishing that block figure as though it were the cartridge voltage is a common error on other listings, and it makes the pack look far smaller than it is. Order by UPS model number and the voltage question does not arise; if you need it confirmed for a technical submission, ask us and we will get it in writing from the distributor.
Can I fit the cartridge myself, and can it be done without shutting the UPS down?
The cartridge ships fully assembled with its connectors already fitted, so mechanically 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. Schneider rates the cartridge for operation up to the temperature shown in the specifications above; running near that ceiling 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 a battery recycling guide with the cartridge, and SourceIT can arrange collection of the exhausted pack for proper recycling when the replacement is delivered — tell us when you order so it is scheduled with the delivery.
Is this a genuine APC part, and what does the warranty cover?
Yes. Every APC Replacement Battery Cartridge #157 (APCRBC157) sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the APCRBC157 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.
