Features & Advantages
🚀 Engineering Excellence
⚡ Precision Power for Apple Silicon
The M2 and M3 chips are marvels of efficiency, and they require a battery that can keep up. Our A2797 unit delivers a consistent 11.55V output with a nominal capacity of 66.5Wh. This matches the strict power delivery requirements of the Liquid Retina display and 8-core CPU, ensuring no throttling or unexpected shutdowns.
🧬 Decoded BMS Architecture
Modern MacBooks are sensitive to non-original parts. Our engineering team utilizes a fully decoded Battery Management System (BMS) that seamlessly handshakes with the logic board. This means instant plug-and-play functionality, accurate “Time to Empty” calculations, and standard charging speeds via MagSafe 3.
🛡️ Automotive-Grade Safety Standards
Safety is non-negotiable. We employ Automotive-Grade Li-Polymer cells that undergo rigorous thermal shock and puncture tests. Combined with multiple circuit protections (Over-charge, Over-heat, Short-circuit), our batteries are built to exceed global safety standards like IEC62133 and UL.
🔧 Streamlined Repair Workflow
Time is money for technicians. Each A2797 battery features laser-cut adhesive films pre-installed on the back. This mirrors the original assembly method, allowing for a clean, secure, and fast installation process without the need for messy third-party tapes.

Our Quality Commitment: How We Manufacture Your Laptop Batteries
At Balder Power, transparency in our manufacturing process is the foundation of our partnership with you. We adhere to rigorous industrial standards to ensure that every battery you receive is stable, safe, and high-performing.
Every single cell entering our production line must pass through strict capacity grading. We utilize high-precision grading cabinets to measure the actual capacity, internal resistance, and voltage of each cell. By grouping only perfectly matched Grade A cells, we prevent premature degradation and ensure an extended cycle life for the final battery pack.
We utilize advanced high-speed automated assembly lines to weld individual lithium cells into unified packs (e.g., 3-cell or 6-cell configurations). Laser-controlled precision welding ensures ultra-low internal resistance and uniform connectivity across all nickel tabs, providing significantly higher structural integrity and current stability than traditional manual welding.
The Battery Management System (BMS) is the brain of the battery. Our protection boards are manufactured on fully automated SMT (Surface Mount Technology) lines. This automation eliminates human error, ensuring that every safety component—from overcharge protection to short-circuit safeguards—is soldered with microscopic precision for consistent electronic stability.
Superior final assembly is critical for efficient current conduction. Our expert technicians utilize professional pulse spot-welding equipment to join the completed cell packs with the BMS boards. This process ensures low-resistance connections that can easily handle the high-wattage demands of modern laptops while remaining structurally sound under thermal stress.
Quality is found in the details. Every battery undergoes a meticulous visual inspection after assembly. Beyond checking for aesthetic defects, we use precision calipers to verify that the housing matches 1:1 OEM dimensions, ensuring a perfect fit in the laptop bay without being too tight or too loose.
Every finished battery must undergo at least two full charge-and-discharge cycles on our aging racks. During this process, we monitor voltage curves and temperature changes in real-time. Only batteries that demonstrate flawless performance under high-intensity stress tests are approved for the next stage.
Every single cell entering our production line must pass through strict capacity grading. We utilize high-precision grading cabinets to measure the actual capacity, internal resistance, and voltage of each cell. By grouping only perfectly matched Grade A cells, we prevent premature degradation and ensure an extended cycle life for the final battery pack.
The final step is specialized packaging designed for global logistics. Each battery is sealed in an Anti-Static (ESD) bag and placed within custom-fitted, shock-absorbent lining. Our packaging meets international standards for Class 9 Dangerous Goods, ensuring safe arrival and a premium unboxing experience for your retail customers.
