It features four sealed lead-acid batteries in a durable, flame-retardant enclosure, plugs directly into the UPS for automatic recharging, and is backed by a 2-year warranty—perfect for professionals demanding uninterrupted power during critical outages. ## Description Extend the runtime of your APC Back-UPS Pro 1500VA UPS with the BR24BPG External Battery Pack. Designed exclusively for compatible 1500VA Back-UPS Pro model BR1500G, this supplemental battery pack plugs directly into the rear panel of your UPS, adding four 9Ah, 24-volt batteries to the two 9Ah batteries already built into your unit. Adding the BR24BPG approximately triples your UPS's total runtime — for example, extending a 1500VA Back-UPS Pro from roughly 80 minutes to over 230 minutes at a 100W load — giving you significantly more time to work, game, or keep essential electronics running through longer power outages. The battery pack recharges automatically through your UPS's built-in charger, so there's no separate charging equipment to manage, and a heavy-duty, proprietary connector plugs securely into place for a stable, reliable connection. The vented, flame-retardant, leak-proof housing is engineered for durability and efficient thermal management, with styling that matches your Back-UPS Pro unit for a clean, consistent look. Sealed, maintenance-free lead-acid batteries are built for a 4–6 year expected battery life. Backed by a 2-year limited warranty from APC, the BR24BPG is the ideal way to add hours of extra backup power to your existing 1500VA Back-UPS Pro system — sold separately from the UPS unit itself. ## Features - Extended Runtime Capacity: This external battery pack adds an additional 1500VA to your APC model BR1500G UPS (sold separately), providing up to 5 times longer runtime for critical systems - Supplemental Battery Compatibility: This product is a supplemental battery that can only be used with APC model BR1500G (sold separately); THIS SUPPLEMENTAL BATTERY PACK DOES NOT WORK ON ITS OWN OR CHARGE ON ITS OWN - Convenient Recharging System: This external battery pack is recharged when plugged into APC UPS model BR1500G (sold separately) - Warranty Coverage: This BR24BPG APC battery backup supplement comes with a 3-year repair or replace warranty - Enhanced Power Protection: Extends the duration of time that you can protect your electronic devices from damage and disconnect due to unexpected blackouts, voltage fluctuations, and other power disruptions ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0047E5B90 | | Amperage | 24 A | | Battery Cell Type | Lead Acid | | Best Sellers Rank | #39 in Computer Uninterruptible Power Supply Units | | Brand | APC | | Built-In Media | Back-UPS Pro External Battery Pack (for 1500VA Back-UPS Pro models), User manual | | Color | Black | | Connector Type | IEC 320 C13 | | Customer Reviews | 4.7 4.7 out of 5 stars (473) | | Enclosure Material | Information Not Available | | Form Factor | Rack | | Frequency Range | 50/60 Hz (± 3 Hz) | | Global Trade Identification Number | 00731304268789 | | Item Dimensions | 19.5 x 16 x 9.5 inches | | Item Dimensions D x W x H | 19.5"D x 16"W x 9.5"H | | Item Highlight | Extended runtime battery pack exclusively for APC Back-UPS Pro model BR1500G.

Is it a simple beep and it over, or is it like a screeching banshee chasing its prey?** A: Our model produces a continuous high-pitched beep that wouldn't stop until forced shutdown by depressing the power button for several seconds (like a laptop). **Q: How long can the battery keep on a 800 watt machine when the power is off?** A: Just because you have an 800W supply does not mean you are using 800 watts. I have an 800 watt supply and it typically uses only 90-110W. However I never got close to the advertised run times even with a brand new battery. I got about 75-80% of the advertised run times even with a calibrated 30% load. Also the run time that the machine reports is also a bit optimistic. When it was new it was claiming around 60 minutes and was getting about 50 at best. Now that the battery is 3 years old, it only reports about 28 minutes and but only can hang on about 18 minutes. **Q: Description says surge protection is rated at 355 joules -- not much protection at that low rate. Is this correct? Thanks.** A: You are correct. APC's site lists it at 354 joules. That is pretty low compared to a good power strip at nearly 10 times that rating. If you live in an area with surge problems (i.e. lightning), then you could plug the UPS into a good power strip first ... or rely on APC's connected equipment protection warranty. **Q: If the input/output voltage for the addon battery pack is 12vdc, could a deep cycle be used by the unit in theory? The packs that power it are simply sealed wet cells anyway.** A: The original battery pack is rated at 9Ah. The external battery pack is about 18Ah. Meaning the charging circuit is designed to manage safely a 24 Volt 27 Ah battery set safely. The UPS has a fan which start when required, so I think you could go up to a couple of 12 Volt 35 Amp AGM type battery in series without any risk but after that size I think it's too much for this UPS model and will take too much time to fully recharge the batteries and perhaps overheat it. Also keep in mind if you hook a USB cable to feed UPS status info to a computer, the UPS will report a false reserve time and will force to shut down the computer well before it's discharged. ## Frequently Bought Together - APC External Battery Pack, BR24BPG, Supplemental Battery for UPS Model BR1500G (Sold Separately) - APC UPS Battery Replacement, APCRBC124, for APC UPS Models BR1500G, BX1500M, BR1300G, SMC1000-2U, SMC1000-2UC, BR1500GI, BX1500G, SMC1000-2U, SMC1000-2UC, and select others - SafeAMP UPS 9Ah, 24VDC VRLA Battery Replacement APCRBC124 Compatible with APC UPS Models BR1000G, BX1350M, BN1350G, BX1000G, BX1300G.… --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/1863260-apc-external-battery-for-extended-runtime-for-back-ups-pro](https://www.desertcart.fr/products/1863260-apc-external-battery-for-extended-runtime-for-back-ups-pro) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-09-20*
