Product Description
Keep Your Equipment Protected. Don't Let a Dead Battery Be the Reason It Isn't.
A UPS is only as good as the battery inside it. When that battery fails, your computers, network equipment, and connected devices are exposed — one power surge or outage away from data loss, hardware damage, or an unplanned shutdown at the worst possible moment. The RBC4 Replacement Battery gets your APC UPS back to full protection quickly, with a battery built to match your system's original specs.
A True Drop-In Replacement
This battery is engineered as a direct replacement for the APC RBC4. At 12 volts and 12Ah, it matches the voltage and capacity of your UPS's original battery precisely. The physical dimensions — 5.90" long × 3.70" wide × 3.90" tall — ensure it fits correctly inside the enclosure without forcing, shimming, or modification. Reconnect the terminals and you're done.
Sealed Lead Acid — Reliable, Maintenance-Free
Like the original APC battery it replaces, this is a sealed lead acid (SLA) battery. That means no maintenance, no need to check fluid levels, no special ventilation requirements. Once it's installed, it does its job quietly in the background until you need it — which is exactly what you want from a UPS battery.
Backed by an 2-Year Warranty
We stand behind this battery with an 2-year warranty — more coverage than you'll find on most third-party replacements. If there's a defect, you're covered. That kind of warranty on a replacement battery matters, because your UPS exists to protect equipment that's worth far more than the battery itself.

Frequently Asked Questions
Is this battery as good as the original APC RBC4?
Yes. This battery uses the same sealed lead acid chemistry, voltage, and capacity as the original APC RBC4. It's manufactured by WSP to the same specifications and will restore your UPS to full runtime capacity. The main difference is price — third-party replacement batteries cost significantly less than APC's branded cartridges while delivering equivalent performance. We back this with an 2-year warranty.
How do I know if my UPS uses an RBC4 battery?
Check your UPS model number against the compatibility list above. If your model is listed, it uses the RBC4. You can also open your UPS battery compartment and look at the existing battery — if it's marked "RBC4" or measures approximately 5.90" x 3.70" x 3.90", this replacement will fit. When in doubt, take a photo of your current battery (including any labels) and contact us for verification before ordering.
How much runtime will I get with this battery?
Runtime depends on the load connected to your UPS. A fully charged 12Ah battery in a 650VA UPS powering a desktop computer and monitor (approximately 200-300W load) typically provides 10-20 minutes of backup time. Lighter loads (just a modem and router, for example) can run for an hour or more. Heavier loads (multiple computers, servers, or high-power equipment) will drain the battery faster. Check your UPS manual or the APC website for runtime charts specific to your model and typical load scenarios.
Will this void my UPS warranty?
No. In the United States, the Magnuson-Moss Warranty Act prevents manufacturers from voiding warranties simply because you used a third-party replacement part. Using a compatible replacement battery will not void your APC UPS warranty. However, if you have an active warranty on your UPS and it's experiencing battery issues, you may want to contact APC first — they may replace the battery under warranty at no charge.
How long will this replacement battery last?
Under typical conditions (moderate room temperature, occasional discharge cycles), sealed lead acid UPS batteries last 3-5 years. Factors that shorten battery life include high temperatures (above 77°F/25°C), frequent deep discharges, and letting the battery sit uncharged for extended periods. To maximize lifespan, keep your UPS in a cool, well-ventilated area and plug it in continuously so the battery stays charged.
Do I need to charge the battery before installing it?
The battery ships with a partial charge but should be fully charged before relying on it for backup power. Install it in your UPS, plug in the UPS, and let it charge for 8-12 hours (or overnight) before using it for battery backup. The UPS will charge the battery automatically once connected. Some UPS models may beep or show warnings until the battery is sufficiently charged and passes the self-test.
Can I recycle my old UPS battery?
Yes, and you should. Lead-acid batteries are highly recyclable and should never go in household trash. Most battery retailers (including auto parts stores, hardware stores, and battery specialty shops) accept used SLA batteries for recycling, often at no charge. Some municipalities also have hazardous waste collection programs that accept batteries. Check with your local recycling center or waste management authority for options in your area.
What if the replacement battery doesn't fit or work?
If you've verified your model number is on the compatibility list and the battery doesn't fit or function properly, contact us immediately. We'll work with you to resolve the issue, whether that means sending a replacement or processing a return. Common issues include incorrect model identification (some APC models look similar but use different battery sizes) or receiving a defective battery, both of which we can address quickly.
