Battery BTI A1705-BTI MacBook Retina 12

Keep supported MacBook Retina 12-inch systems working through the day with a replacement internal battery engineered for exact-fit compatibility. This BTI pack is designed for Apple MacBook notebooks including Retina 12 IN A1527 and A1534 early 2015 models, as well as the 12-inch Silver and Gold variants from the same generation. With 7.56 V DC output and 5,474 mAh capacity, it restores the runtime users expect from a portable system without forcing a full device replacement. Built with lithium polymer chemistry and a rechargeable design, this battery is suited for service teams replacing worn original packs in premium ultralight notebooks. The proprietary battery size supports the internal layout of the MacBook 12-inch platform, helping maintain the slim profile and factory integration of the system. For procurement teams and repair operations, the 18-month limited warranty adds confidence when standardizing on a replacement part that needs to perform reliably after installation. Choose this BTI battery when uptime, fit, and compatibility matter more than a low-cost generic substitute. It is a practical way to extend the service life of a MacBook that still has value in executive, field, or mobile workstation roles.
