showing these signs?
Battery capacity degrades naturally over charge cycles. When symptoms appear, a replacement restores full-day performance at a fraction of the cost of a new Mac.
A healthy MacBook battery lasts 8–12 h. When it barely makes it through a meeting, charge cycles have used up the cells — time to replace.
Mac shuts off at 30 % or higher — battery voltage drops suddenly under load. The OS can't keep up with the real capacity.
Check System Settings → Battery → Battery Health. 'Normal' means the battery works as it should; 'Service Recommended' means it holds noticeably less charge than when new. Apple says the Mac is still safe to use — replace it when the runtime gets in your way.
The trackpad feels raised, or the bottom case is lifting. Swollen Li-ion cells are a fire risk — stop using and book replacement immediately.

“Andrei responded very quickly and offered me a time on the same day, thoroughly cleaned the laptop and replaced the thermal paste. All for a good price, and now my laptop runs much better!”
“My gaming laptop was bit slow, so decided to call Andrei for cleaning internal parts and replacing thermal paste. The work was done neatly and I am happy with his excellent work. Also, We had some nice discussions during the work. I strongly recommend Andrei for any system related issues.”
“Very professional and good customer service. They cleaned my 4 years old gaming laptop completely and replaced the old liquid metal (which I didnt’t want to touch personally) and old thermal paste. Price was very reasonable and they used quality tools & thermal products. All was completed in about an hour in my home as they do home-runs. Definitely recommended service for your gaming product every three to four years.”

How do I know when the MacBook battery needs replacing?+
Open System Settings → Battery → Battery Health. If it says 'Service Recommended', or the cycle count is past 1000 (the limit Apple gives for MacBooks of the last fifteen years), it's time. Also: if your Mac shuts down unexpectedly above 20 %, or the runtime has dropped from 8–10 hours to 2–3, the battery is past its life. We check this for free before any work.
How long does MacBook battery replacement take?+
The cell is ordered for your exact model and arrives in 3–5 business days. The swap itself is about 1–1.5 hours at your place — we book 2 hours to be safe and won't rush if the old adhesive is stubborn.
Do you use genuine Apple batteries?+
We use cells that match Apple's original specifications for your exact model — same capacity, same connector, same BMS chip. These are not OEM Apple batteries (Apple doesn't sell those separately), but they register correctly in System Settings and carry our 1-year warranty.
Does opening the MacBook void the warranty?+
If your Mac is still under AppleCare+, opening it will void that specific coverage. Most MacBooks more than 1–2 years old are past warranty anyway. We give our own 1-year warranty on the replacement battery and labour.
What if the battery is swollen?+
Stop using the Mac immediately — swollen Li-ion cells can vent or ignite. Don't force the case. Contact us and we'll arrange an urgent visit. We handle swollen batteries with proper tools and dispose of the old cell safely.
Can you also clean the MacBook while you're here?+
Yes — we can combine battery replacement with a full cleaning (fan dust removal + thermal paste replacement, +€30). Many customers do both at once since the machine is already open.
A degraded battery
gets worse, not better.
Lithium cells don't recover. Each charge cycle the capacity drops a little more — waiting only shortens runtime and increases shutdown risk.
Apple designs a MacBook battery to keep up to 80 % of its original capacity at 1000 cycles. Past that it keeps losing capacity, and a charge that used to last the day stops lasting the afternoon.
A worn battery can drop out under load while the menu bar still shows charge left. The Mac turns off mid-call or mid-export, and you lose whatever wasn't saved.
Old cells can swell and push up the trackpad or bottom case. A swollen battery is a fire risk and makes the repair more complex (adhesive is harder to remove).
If the rest of the Mac is fine, the battery is the part that's worn out — and it costs from €149 to replace, not the price of a new laptop. The calculator above gives the exact price for your model.
