Swollen battery — act fast
Stop using a swollen-battery MacBook
If the trackpad is lifting or the case is bulging: power off, do not charge, do not press the trackpad down, and bring it to us (or book free pickup). Swollen lithium batteries are replaced as a priority — continued charging can worsen the swelling.
Frequently asked questions
How much does MacBook battery replacement cost in Singapore?
MacBook battery replacement depends on the model — MacBook Air batteries cost less than MacBook Pro batteries, and Retina/Pro models use glued-in packs that take longer to service. Diagnosis is free and we confirm the exact price for your model before work begins.
How do I know my MacBook battery needs replacement?
Signs: battery health below 80% (check → About This Mac → System Report → Power), sudden shutdowns, the case bulging or trackpad lifting (swollen battery — stop using it and bring it in), 'Service Battery' warning, or needing the charger constantly.
How long does MacBook battery replacement take?
Typically 1–2 hours at our workshop if the battery is in stock; some Pro models require more careful opening. We confirm the turnaround at diagnosis.
Is a swollen MacBook battery dangerous?
Yes — a swollen lithium battery can damage the trackpad and chassis and should not be ignored or punctured. Power the MacBook off, do not charge it, and bring it in promptly. We replace swollen batteries as a priority.
Do you use original batteries?
We fit genuine-grade (OEM) batteries with cycle counts and safety circuitry matching Apple specifications, backed by our parts-and-labour warranty. The grade and warranty are stated on your invoice.
Can I check my MacBook battery health myself?
Yes: hold the Option key and click the Apple menu → System Information → Power, or → About This Mac → System Report → Power. 'Condition' shows Normal / Replace Soon / Service Battery, and cycle count is listed below.
