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 this A2389 battery work for both M1 and Intel MacBook Air?
Yes! The A2389 battery is cross-compatible. It fits the Early 2020 MacBook Air (A2179, Intel Core) and the Late 2020 MacBook Air (A2337, M1 Chip). It uses the same connector and form factor.
Q2: Is the 55Wh capacity safe for my MacBook Air?
Absolutely. The 55Wh capacity is achieved through higher density cell technology within the same physical dimensions. The voltage (11.4V) remains identical to the original, ensuring perfect safety and compatibility while offering longer runtime.
Q3: What is the minimum order quantity (MOQ) for wholesale?
We are flexible. For new partners, our MOQ starts at 5 pieces for testing purposes. We strongly recommend our ‘Starter Pack’ of 20 units to get the best shipping rate per unit.
Q4: How do I replace the A2389 battery?
The A2389 battery is secured with adhesive pull-tabs and screws. However, the trackpad cable runs over the battery, so care must be taken. We can provide removal tools upon request.
