MacBook Battery Replacement
Whether your MacBook Air or Pro shows "Service Recommended," dies by lunchtime, or has a battery swelling under the trackpad, we replace it safely with a genuine-grade cell — and we check the charging circuit first, because a battery that won't charge is often the board, not the cell.
MacBook batteries are glued into the top case on most models, and on some Retina MacBook Pros the cells sit directly over the trackpad. We've spent 11 years doing board-level and microsoldering work, so we remove swollen or bonded cells with solvent and patience instead of brute force — and we test the actual charging path before we hand it back.
When you need a battery replacement
- System Settings (or System Information) shows "Service Recommended" or "Service Battery" — capacity has dropped below 80 percent or cycles are spent
- The battery is swelling — the bottom case bulges, the laptop rocks on the desk, or the cells are lifting the trackpad from underneath
- It dies fast — full charge to dead in an hour or two, far short of what the machine used to hold
- It won't charge at all, or charges to a point and stops — which can be the cell or the charging circuit on the logic board
- It shuts down the moment you unplug, running fine only on the adapter
- The trackpad clicks oddly, feels stiff, or won't click — a classic sign of a swollen cell pressing up against it
Honest by default
Every device starts with a $65 diagnostic and a written report — exact cost and timeline before we touch it. The fee applies toward your repair.
Cost depends on the model, whether the battery is a modular pack or glued into the top case, and whether you want a genuine-grade or a cheaper cell — we'll always recommend the genuine-grade option and explain the trade-off. Our $65 written diagnostic is the starting point and applies toward your repair. If the issue turns out to be the charging circuit rather than the cell, the diagnostic tells you that before you spend on a battery that wouldn't have fixed it.
Our battery replacement process
Safe removal of swollen or glued cells
We open the top case carefully and release the adhesive with the correct solvents — slow and methodical, never prying a pressurized cell. On Retina Pros where the battery is bonded over the trackpad, that care is the difference between a clean swap and a punctured cell or a damaged trackpad.
Genuine-grade replacement cell
We fit a quality genuine-grade battery, not a bargain pack. We'll tell you honestly what we're using and why — cheap cells under-deliver on capacity and age fast, and on a machine you rely on, that's a false economy.
SMC and charging-circuit check
Before we call it a battery, we verify the charging path — SMC behavior, the charging IC and its feedback components, port and power negotiation. If your old battery wouldn't charge, we confirm the board can actually charge the new one, so you don't pay for a cell that the logic board can't feed.
Calibration and load test
We let the new cell settle, confirm macOS reads correct capacity and condition, run it through charge and discharge, and check that battery health management and cycle reporting are clean before you pick it up.
What does "Service Recommended" mean on my MacBook battery?
It means macOS has measured your battery's capacity below roughly 80 percent of original, or it has reached its cycle limit. The Mac still runs, but you'll get noticeably less time per charge. It's macOS telling you the cell is worn — replacement restores full runtime.
Is a swollen MacBook battery dangerous?
Yes. A swollen cell is under pressure and can fail thermally if punctured or kept in use. Stop using the laptop, don't press on the bulge, and keep it away from heat. Bring it in — we remove swollen cells safely. Don't try to pry it out yourself.
Why is MacBook battery replacement harder than other laptops?
On most MacBooks the battery is glued into the top case with industrial adhesive, and on some Retina Pros it sits right over the trackpad. It has to come out with solvent and patience, not force. Done wrong, you puncture a cell or wreck the trackpad — which is why this is board-level shop work.
My MacBook won't charge — is it the battery or the logic board?
Either. A worn cell can refuse a charge, but so can a fault in the charging circuit — the charging IC, feedback resistors, or power negotiation on the board. We check the charging path before fitting a battery, so you don't buy a cell the board can't actually charge.
How long does a MacBook battery replacement take?
It depends on the model and how the cell is bonded — glued top-case batteries take longer than modular packs because removal can't be rushed. We give you a realistic timeframe with your diagnostic, and tracked mail-in service is available across all 50 states.
What warranty comes with the new battery?
Genuine-grade and OLED-class work carries a 1-year warranty; aftermarket parts carry 1 month. We'll tell you which grade your repair uses before we start, so there are no surprises.
Why WeFixed for MacBook batteries
Most shops mail MacBook battery work out — we do it in-house in our Clarendon lab. Eleven years of board-level and microsoldering work means we handle the hard parts ourselves: easing glued and swollen cells out of the top case without nicking the trackpad, and checking the charging circuit so a "won't charge" fault doesn't get misdiagnosed as a dead battery. We use genuine-grade cells, we're honest about grade and cost up front, and we never sell your data.
