MacBook Battery Replacement

Typical signs of a defective MacBook battery

• Swollen battery, case bulges, trackpad is hard to press or sticks
• Runtime under 2 hours (versus 6-8 originally)
• Battery no longer reaches 100% or the level drops fast
• MacBook shuts down without warning, even when charge is shown
• macOS notice "Battery, Service Recommended" or "Replace Soon"
• Device feels noticeably slow: when the battery is weak, macOS throttles the CPU

If the battery is swollen: power off immediately, disconnect power adapter, do not charge. A swollen battery can become dangerous, please come to us or another shop without delay.

On modern MacBooks the battery is glued in. Apple and many shops therefore replace the entire top case along with the keyboard and trackpad. We extract the battery individually from the chassis and replace only the cell. Your original keyboard, trackpad and lettering stay in place, and the price drops accordingly. We use high-cobalt cells made to our spec, which hold up better than the third-party batteries typically used elsewhere. 12-month warranty on the replacement.

Check your MacBook battery health yourself: Before having it replaced, check the battery capacity. On macOS Sonoma/Sequoia: Apple menu → About This Mac → More Info…, then at the bottom System Report… → Power. There you'll see the cycle count and battery condition ("Normal", "Service Recommended", or "Replace Soon"). Over 1,000 cycles or status "Service" are clear signals to replace. Reading these out is part of our free analysis. We additionally check SMC data, charge currents and voltage curves that Apple doesn't show you.
