Product Description
Revitalize the Classic: Premium A1245 Battery Replacement for First-Gen MacBook Air
The original MacBook Air (A1237/A1304) revolutionized the laptop industry. However, finding a reliable power source for these vintage machines is a challenge. Most market options are “dead stock” (batteries manufactured years ago that have lost chemical activity).
At Balder Power, we solve this supply chain issue. As a specialized Wholesale A1245 Battery manufacturer, we produce this model in fresh batches to support professional repair shops, IT refurbishers, and eBay/Amazon sellers. Our A1245 Battery Replacement is not old inventory; it is newly manufactured using modern Li-Polymer technology to ensure peak performance.
Why Freshness Matters for A1245? Lithium polymer batteries degrade over time even when not in use. Our “Fresh-Cycle” production guarantees that the MacBook Air 13 A1237 Battery you receive has low internal resistance and can hold a charge just like the original did in 2008.
Compatibility Note: This battery features the specific connector and form factor for the MacBook Air 13-inch (Early 2008, Late 2008, and Mid 2009) versions. It is the lifeline for keeping these classic collectible machines functional.

Features & Advantages
🔋 High Density 5200mAh Capacity Don’t let your customers down with weak batteries. Our 37Wh / 5200mAh capacity provides extended runtimes, perfect for web browsing and document editing on legacy MacBook Air models.
🌡️ Precision Thermal Management The A1237/A1304 chassis is notoriously tight with limited airflow. Our battery integrates high-grade thermal sensors that communicate with the MacBook’s SMC (System Management Controller) to regulate temperature and prevent swelling—a common issue with low-quality clones.
🛠️ Perfect OEM Fitment Installation of the MacBook Air A1304 Battery requires precision. Our molds are 1:1 replicas of the original Apple design, ensuring the screw holes align perfectly and the ZIF connector seats securely without stressing the delicate flex cable.
💼 B2B Wholesale Support We understand the needs of the trade. Whether you need 5 units for a repair shop or 500 units for a refurbishment project, Balder Power offers tiered pricing, neutral packaging options, and rapid shipping via certified dangerous goods channels.

FAQ
Q1: How can I tell if I need the A1245 battery or the newer A1405/A1377? The A1245 is only for the original MacBook Air design with the fold-down port door (Years 2008-2009). If your MacBook Air has ports directly on the side (2010 onwards), you do not need this battery. Check the bottom case for model “A1237” or “A1304”.
Q2: Are these batteries “New Old Stock” or newly manufactured? Balder Power supplies Newly Manufactured batteries. We understand that Li-Polymer degrades over time. We run specific production lines for legacy models like the A1245 to ensure distributors receive fresh cells with full capacity, not aged stock from 2015.
Q3: Does the A1245 replacement battery come with screwdrivers? For wholesale bulk orders (industrial packaging), tools are not included to optimize shipping volume. However, for retail-ready packaging orders, we can include the necessary Phillips #00 and Pentalobe drivers upon request.
Q4: What is the warranty rate for these older model batteries? Thanks to our Grade A+ cell selection and modern BMS technology, our defect rate is below 1%. We offer a full 12-month warranty for our B2B partners, providing free replacements for any manufacturing defects.
Q5: Can you ship A1245 batteries to Europe or the USA? Yes. We are a fully certified exporter. Our batteries comply with UN38.3 and are packed according to PI965 regulations. We handle the dangerous goods declaration for air and sea freight to ensure smooth customs clearance.
Q6: Is it difficult to replace the A1237/A1304 battery? It is moderately easy but requires care. The bottom case screws must be removed, and the connector is delicate. We recommend this be performed by professional technicians. We can provide a digital installation guide for your customers.
