Genuine B31N1726 High-Performance Battery | OEM Power for ASUS TUF Gaming & FX/FA Series Laptops
Power Your Fights – The Official Energy Core for Gaming Durability
Fuel your gaming marathons with the endurance your rig deserves. This Genuine B31N1726 High-Performance Battery is the official ASUS power component, engineered for the rugged TUF Gaming and FX/FA series laptops, including the FX80/FX86, FX504 variants (FX504G/GD/GE/GM), FX505 models (FX505DT/DV/DU), and modern FA506IU (A15), FA706II (A17). Delivering a robust 48Wh at a stable 11.4V, this battery provides the essential power buffer needed to sustain your system during critical gaming sessions, sudden outages, or when you need to untether for mobility, ensuring your gameplay remains uninterrupted.
Your TUF laptop is built to endure; its power source should be equally resilient. Third-party batteries risk disrupting the precise balance of ASUS’s power delivery and thermal management, potentially causing unexpected FPS drops, system instability during GPU-intensive scenes, or charging failures. Our genuine battery ensures seamless integration with ASUS Armoury Crate for power profile control, supports stable performance across all operating modes, and provides accurate battery health data. It’s the smart, reliable investment for gamers who value consistent performance and system longevity.
Why This Genuine ASUS Gaming Battery is the Tactical Choice
-
Guaranteed Stability Under Gaming Loads: The precise 11.4V output is calibrated to support the laptop's power-hungry NVIDIA GeForce GTX/RTX or AMD Radeon graphics and multi-core processors. This prevents voltage sag that can lead to sudden performance throttling or crashes during intense gaming moments, ensuring your frame rates stay stable when it matters most.
-
Essential Mobility for Gaming & Productivity: The 48Wh capacity offers a practical balance, providing crucial unplugged runtime for finishing matches, moving between setups, or handling tasks away from an outlet. It’s the reliable backup that ensures your gaming and work aren't abruptly cut short.
-
Protect Your System's Integrity & Cooling Performance: Designed to ASUS's exact thermal and electrical specifications, this battery helps maintain the laptop's intended cooling efficiency and power delivery. Using non-genuine parts can interfere with fan curves managed by Armoury Crate and potentially lead to overheating. It also preserves your device's warranty coverage and resale value.
