FAQ for Laptop Batteries
A: We can typically design packs ranging from 40Wh to near the 100Wh IATA flight limit, depending on the available internal volume and the thinness of the chassis.
A: Yes, we design our battery packs and select cells that are fully compatible with modern fast-charging standards like USB-C Power Delivery, ensuring rapid and safe charging.
A: Due to the complexity of pack design, tooling, and certification, our MOQ for a new custom laptop battery typically starts at 20,000 to 50,000 units.
A: Safety is our highest priority. We use an intelligent Battery Management System (BMS) that constantly monitors the voltage, current, and temperature of each cell block. It provides cell balancing and multiple layers of protection against faults, in addition to using cells that are individually certified.
A: Our standard is to engineer packs that retain over 80% capacity after 800 charge cycles. For commercial and premium models, we can design for 1000+ cycles.
A: Yes, creating complex, non-rectangular battery packs to maximize capacity is a core competency and a key service we provide to leading laptop brands.
A: After prototype approval and design freeze, the lead time to ramp up for mass production, including tooling and final certifications, is typically 10-14 weeks.
A: Absolutely. We integrate smart BMS solutions that communicate with the host system via standard protocols like SMBus, providing accurate battery status, health, and charging information to the operating system.
A: We manage all necessary certifications for global sale, including IEC 62133, UL 2054 (for the pack), CE, and UN38.3 for transportation.
A: Please provide a 3D model of the available battery space, target capacity (Wh) or runtime, target voltage (e.g., 11.1V, 15.2V), charging/discharging power requirements, and your estimated production volume.
