Features & Advantages
🚀 Engineering Features
⚡ True 52.6Wh Capacity for M2 Efficiency
The M2 chip is powerful yet efficient, but it relies on stable voltage. Our A2669 battery delivers a consistent 11.54V output with a rated capacity of 52.6Wh (4558mAh). We strictly adhere to the original specification to ensure the device meets the expected “all-day battery life” without overheating or throttling under load.
🧬 Decoded TI BMS Architecture
Avoid post-repair headaches. We utilize a fully decoded Texas Instruments (TI) Battery Management System chip. This ensures the MacBook immediately recognizes the new battery health status as “Normal” (100%), bypassing common firmware locks found in lower-quality aftermarket parts.
🛡️ Automotive-Grade Li-Polymer Cells
To fit the ultra-thin A2681 chassis, we use high-density Cobalt-Oxide Polymer cells. These cells undergo rigorous grading to ensure consistent internal resistance. They are designed to withstand 800+ charge cycles while maintaining 80% capacity, offering your customers long-term reliability.
🔧 Technician-Centric Design
Time efficiency is critical for repair shops. Every A2669 unit comes with OEM-style stretch-release adhesive strips pre-applied. This mirrors the factory assembly, allowing for a clean, secure installation that sits perfectly flush inside the unibody casing, preventing trackpad interference.

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.

FAQ
Q1: Does the A2669 battery fit the older M1 MacBook Air (A2337)?
No, it does not. The M2 MacBook Air (A2681) features a completely redesigned chassis. The A2669 battery has a different shape and connector compared to the A2389 battery used in the M1 Air. They are not interchangeable.
Q2: Does this battery require BMS board transplantation?
No. Our A2669 battery comes with a fully integrated, high-quality BMS board. It is a direct plug-and-play solution. You do not need to perform spot welding or move the original BMS from the old battery.
Q3: What is the MOQ for wholesale orders?
We support flexible procurement. For repair shops, our MOQ starts at just 5 units. For distributors seeking volume discounts, we offer tiered pricing for 50+ and 100+ unit orders.
Q4: Is the installation adhesive included?
Yes, every A2669 battery ships with pre-installed stretch-release adhesive strips, identical to the OEM specification. This ensures a secure fit and simplifies the installation process.
Q5: Is it safe to ship internationally?
Yes. Our batteries are fully certified with UN38.3 and MSDS reports. We have established logistics channels to ship dangerous goods (Class 9) via Air or Sea to the USA, Europe, and Asia safely.
Q6: How do you ensure battery health reporting?
We use premium TI Gauge chips that are decoded to communicate with the M2 logic board. This allows macOS to correctly read the cycle count and battery health percentage without third-party tools.
