5 Signs Your MacBook Battery Needs Replacing – and Where to Get It Done

Your MacBook is built for performance—but like all lithium-ion devices, its battery won’t last forever. Over time, you may start noticing slower performance, shorter battery life, or even swelling. Knowing when to replace your battery is essential to keep your device running safely and efficiently. 

In this guide, we’ll highlight 5 signs your MacBook battery needs replacing, and recommend where to get fast, reliable MacBook battery replacement in Melbourne. 

1. Your MacBook Runs Out of Power Too Quickly 

If your fully charged MacBook used to last 8–10 hours but now barely makes it through 2 or 3, your battery may be on its last legs. Sudden shutdowns or rapid battery drain are common signs of aging cells. 

💡 Tip: Check your Mac’s battery cycle count in System Report > Power. Most MacBook batteries are rated for around 1,000 charge cycles. 

2. Battery Health Warning Appears 

macOS includes a built-in battery health monitoring tool. If you see one of these warnings: 

…it’s time to take action. These alerts mean the system has detected reduced battery capacity or safety concerns.

3. Your MacBook Swells or Feels Warped 

A swollen battery is a serious safety issue. It can warp your MacBook’s casing, cause trackpad issues, or even damage the screen. If you notice the base lifting, keyboard bulging, or touchpad failing to click—power off the device immediately. 

🚫 Do not attempt to puncture or remove a swollen battery on your own. Always seek professional help.
