Sooner or later every MacBook battery becomes a consumable. Budget roughly $129–$249 at Apple, depending on the model (check Apple's estimate for yours) — or read on for how to make that day arrive much later.
Apple's battery service for MacBook Air is typically at the lower end of the range, MacBook Pro models at the higher end — roughly $129–$249 in the US; regional prices vary (Japan: about ¥20,000–¥43,000). Always confirm with Apple's “Get an Estimate” page for your exact model, as prices change.
Under the one-year limited warranty or AppleCare+, Apple replaces batteries that hold less than 80% of original capacity at no charge. If your capacity is flirting with 80% and coverage is about to lapse, get it checked before it expires — see how to check capacity.
Independent shops are often cheaper; quality varies with the cell supplier. DIY kits exist but modern MacBook batteries are glued in, and mistakes are costly. For recent models, official service is usually worth the premium.
Battery wear is driven by time at high charge, heat, and cycles. Cutting the biggest factor — parking at 100% — can meaningfully stretch the years until the 80%-capacity threshold. An 80% charge limit costs nothing to run and works while you sleep: set it up here.
Battery Autopilot automates the whole prevention stack — 80% guard with self-healing, cooler operation via measured power savings, and a full charge only right before departure — for less per year than a tenth of a battery service. The “+minutes extended” readout shows it working every day.

For runtime, yes — you're back to full capacity. It won't speed up the CPU, but it removes the shutdowns and anxiety of a worn cell.
Only if you expect to hit sub-80% capacity within the coverage window — heavy daily cyclers and hot environments, mainly. For most people, prevention is the better investment.
