Product Description
Affordable Alternative to APC Original Batteries
When your APC Back-UPS starts beeping with a "replace battery" warning or no longer holds a charge, you don't need to buy an expensive OEM battery cartridge or replace the entire UPS. This RBC2-compatible replacement battery from WSP delivers the same 12V 7Ah capacity as the original APC battery at a fraction of the cost. It's a direct fit for 35+ APC Back-UPS models, restoring full battery backup runtime and protecting your equipment from power outages and surges just like the day you bought your UPS.
Compatible with Popular APC Back-UPS Models
This replacement battery works with the following APC Back-UPS models that originally shipped with the RBC2 battery cartridge:
BE Series (Back-UPS ES/BE): BE400-LM, BE500-IN, BE500R, BE500R-AS, BE500R-CN, BE500U, BE500U-CN, BE500Y-IN, BE525-AS, BE525-RS, BE550-AZ, BE550-CP, BE550-FR, BE550-GR, BE550-IT, BE550-KR, BE550-LM, BE550-RS, BE550-SP, BE550-UK, BE600-BR, BE600-LM, BE600D-BR, BE700-LM, BE700G3
BK Series (Back-UPS BK): BK200, BK200B, BK250B, BK280B, BK300C, BK300I, BK300MI, BK300MICM, BK300MICW, BK300X116
BH Series: BH500INET, BH500NET
To verify compatibility, check the label on your UPS (usually on the back or bottom) for the model number, or open the battery compartment and look for "RBC2" marked on the existing battery. If your model isn't listed but the battery compartment says RBC2, this replacement will work.
Same Specifications as Original APC Battery
This sealed lead acid battery matches the electrical and physical specifications of the original APC RBC2:
- Voltage: 12 Volts
- Capacity: 7 Amp-hours (Ah) at 20-hour rate
- Chemistry: Sealed Lead Acid (SLA) / Valve-Regulated Lead Acid (VRLA)
- Dimensions: 5.94" L x 2.56" W x 3.94" H (151mm x 65mm x 100mm)
- Terminal Type: F1 (Faston .187" tabs)
- Weight: Approximately 4.8 lbs (2.2 kg)
Because it uses the same sealed lead acid technology as the original, the battery is maintenance-free (no water refilling required) and safe for indoor use in home offices, data closets, or anywhere your UPS is located. The spill-proof design means it can be installed in any orientation without leaking.
Easy Installation
Replacing your UPS battery is straightforward and typically takes 5-10 minutes. Most APC Back-UPS models have a front or side panel that slides or pops off to access the battery compartment. Simply disconnect the old battery's wire harness, slide it out, install the new battery, reconnect the harness, and close the compartment. No tools are usually required beyond what's needed to open the UPS cover (often just a thumbscrew or no fasteners at all).
After installation, plug in your UPS and let it charge for at least 4-8 hours before relying on it for battery backup. The UPS may beep or show a "replace battery" warning initially, but this should clear once the new battery is fully charged and the UPS completes its self-test. Consult your UPS manual if the warning persists after 24 hours of charging.
When to Replace Your UPS Battery
UPS batteries typically last 3-5 years depending on usage, temperature, and how often they're discharged. Signs that your battery needs replacement include:
- UPS beeping continuously or showing a "replace battery" indicator
- Significantly reduced runtime during power outages compared to when new
- UPS failing to switch to battery power during outages
- Battery age exceeding 3-5 years, even if no obvious symptoms
Replacing the battery proactively every 3-4 years ensures your equipment stays protected. It's far less expensive than replacing computers, networking equipment, or data lost due to unexpected shutdowns.
2-Year Warranty
This replacement battery includes an 2-year manufacturer warranty covering defects in materials and workmanship. If the battery fails to hold a charge or exhibits manufacturing defects within the warranty period, we'll replace it at no charge. The warranty does not cover damage from misuse, physical damage, or batteries that have simply reached end-of-life due to normal aging.
Frequently Asked Questions
Is this battery as good as the original APC RBC2?
Yes. This battery uses the same sealed lead acid chemistry, voltage, and capacity as the original APC RBC2. 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 RBC2 battery?
Check your UPS model number against the compatibility list above. If your model is listed, it uses the RBC2. You can also open your UPS battery compartment and look at the existing battery — if it's marked "RBC2" or measures approximately 5.94" x 2.56" x 3.94", this replacement will fit. When in doubt, take a photo of your current battery (including any labels) and contact us for verification before ordering.
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. Install it in your UPS, plug in the UPS, and let it charge for 4-8 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.
