When your MacBook says "Service Recommended", macOS has measured that the battery can no longer hold a useful charge compared with when it was new. You do not have to replace it today, and the Mac is safe to use plugged in, but if it shuts down early or runs out within an hour, replace it now.
Key takeaways
- "Service Recommended" is a status shown in battery settings. It means reduced capacity, not an immediate safety emergency.
- Check Maximum Capacity and Cycle Count. Many recent Mac notebooks are designed to hold about 80 percent of original capacity at 1000 cycles, but check Apple's current specification for your model.
- Replace now if the Mac shuts off unexpectedly, the case or trackpad is bulging, or the battery is swelling. Stop using it and get it inspected.
- Replace later is reasonable if you mostly work plugged in, the machine is stable, and you can tolerate short runtime.
- Prices vary widely by model and provider. See the estimate table, and always compare a quote with the age and value of the Mac.
What "Service Recommended" actually tells you
Every rechargeable battery wears out. Each full charge and discharge is a cycle, and over hundreds of cycles the chemistry slowly loses capacity. macOS tracks this and reports a condition. On current versions you will see Normal when the battery is healthy and Service Recommended when its capacity has dropped enough that Apple considers it worth servicing. Older versions of macOS used labels such as Replace Soon, Replace Now and Service Battery, which meant much the same thing at different levels of urgency.
The message does not predict a failure date. A battery marked Service Recommended can run for months, but it will not behave like a new one. Expect shorter runtime, and sometimes the Mac slowing down or shutting off when the percentage still looks healthy.
How to check your battery health properly
- Open the battery settings. On recent macOS, go to the Apple menu, System Settings, then Battery, and look for the Battery Health information button (often shown as a small "i" icon). It shows the condition and the Maximum Capacity percentage. On older macOS versions, hold Option and click the battery icon in the menu bar to see the condition.
- Read the detailed report. Hold Option, click the Apple menu and choose System Information. Under Hardware, select Power. Note the Cycle Count, Condition and, where listed, Full Charge Capacity. The exact fields vary by macOS version, so treat what you see as a guide.
- Compare against the design limit. Apple publishes a rated cycle count for each Mac notebook model. Check Apple's current support page for your model and compare it with your own count.
- Run Apple Diagnostics. On Apple silicon, shut down and hold the power button until startup options appear, then press Command and D. On Intel Macs, restart and hold D. Diagnostics reports reference codes you can look up on Apple's site. It may flag the battery, but it is not an exhaustive test.
- Do a real-world runtime test. Charge to 100 percent, unplug, play a normal workload and watch how long it lasts and whether the percentage drops in sudden jumps.
Replace now or wait? A simple decision guide
Replace as soon as you can if
- The Mac shuts down at 20 to 40 percent or restarts when you unplug it.
- The battery drains in under an hour of light use.
- The trackpad is raised, the case is lifting, or the lid does not sit flat. A swollen battery is a safety hazard. Stop charging it and have it checked promptly.
- The Mac feels unusually hot while charging. See also our guide to MacBook overheating to separate battery heat from software load.
- You travel with the Mac, and an unreliable battery would cost you work.
It is reasonable to wait if
- The Mac stays on a desk, plugged in most of the day.
- Runtime is shorter but predictable, and it never shuts down unexpectedly.
- The machine is old and you plan to replace the whole computer in the next year.
- You want to budget for the repair or bundle it with another service.
Waiting has a limit. Keeping a worn battery for years can increase the chance of swelling, particularly if the Mac is kept hot or at 100 percent charge for long periods.
Free steps that can extend a tired battery
These steps do not restore capacity, but they can stretch the runtime you have left.
- Find the power hogs. Open Activity Monitor, choose the Energy tab and sort by Energy Impact. Quit or replace apps that sit near the top. Browsers with many tabs, video calling apps and cloud sync tools are frequent offenders.
- Lower screen brightness and turn on Low Power Mode where your Mac supports it (in the Battery settings on recent macOS).
- Keep the Mac cool. Heat is the main enemy of lithium batteries. Do not leave it on a bed or in a hot car.
- Use optimised battery charging. This feature, found in Battery settings, learns your routine and delays charging past 80 percent. It slows ageing but does not repair a worn cell.
- Update macOS. Battery reporting can be corrected by updates. If an update is stuck, our guide on fixing a stuck macOS update explains what to do.
Be wary of advice to "calibrate" a modern MacBook battery by fully draining it repeatedly. It does not restore lost capacity and repeated deep discharges are not recommended.
Model-specific notes
Apple silicon MacBook Air and Pro (M1 and later)
These machines are efficient, so a worn battery often still lasts a full working day, which can hide the problem for a long time. Apple silicon models with a Service Recommended message are normally fine to keep using, but check for swelling. Battery replacement on recent models usually involves removing the battery from the chassis, which on some designs is held with adhesive and strips. This is a job for a technician with the right tools, not a casual home repair.
Intel MacBook Pro, 2016 to 2019
The battery in these models is glued into the top case in the same assembly as the keyboard and trackpad on many versions. Replacement is therefore more involved and more expensive than on older machines. A swollen battery can push up the trackpad or distort the case. If you notice a trackpad that no longer clicks cleanly, or a gap along the case, treat it as a battery problem first.
Older Intel models (2015 and earlier)
Many older MacBooks used a more modular battery. Third-party parts are widely available, but quality varies. Cheap cells can swell and may fail safety standards. If you choose a third-party battery, use a reputable supplier with a warranty.
Mac notebooks that show "Service Recommended" soon after purchase
If the Mac is young and under warranty or covered by a consumer law guarantee, contact the seller or Apple. A battery that falls below expected capacity within the warranty period may be covered. Check the warranty terms for your country.
What does a MacBook battery replacement cost?
Prices depend on the model, whether the battery is glued in, the supplier and your location. Apple, authorised providers and independent repairers all charge differently, and labour is a large part of the price for models where the battery sits under the keyboard.

A quick value check: if the battery quote is above roughly a third of what the Mac would sell for, think about whether the machine is otherwise worth keeping. For a four-year-old Apple silicon laptop that still performs well, a new battery is usually good value. For a Mac that is also slow, has a failing screen or cannot take the latest macOS, the money may be better put towards a replacement.
Safety: what to do if the battery is swollen
- Stop charging the Mac and shut it down.
- Do not press on the trackpad or case, and do not try to puncture or squeeze the battery.
- Keep it away from heat and flammable surfaces, and do not leave it charging unattended.
- Back up data first if the Mac still starts, then arrange a professional replacement.
- Dispose of the old battery through an electronics recycler. Do not put it in household rubbish.
Signs include a trackpad that no longer sits flush, a lid that will not close properly, a case that bulges at the bottom, or a distinctive chemical smell.
When to call a professional
Book a repair if any of the following is true:
- The Mac shuts down suddenly, even with a charge showing.
- The case, trackpad or keyboard looks lifted or deformed.
- Battery Health says Service Recommended and you rely on the Mac away from a power outlet.
- The Mac does not charge, or the charging icon behaves oddly after you tried another charger and cable. This can be a charging port or board problem rather than the battery. Our Mac repair service can diagnose it.
- You are not comfortable opening the machine. Adhesive, delicate cables and sharp tools are a real risk on modern MacBooks.
If you are unsure whether the problem is the battery or the software, we can check remotely first. See our remote Mac support for Canada and remote computer repair for the USA pages.
Not sure what is wrong? Get a diagnosis first.
Our certified tech can connect remotely, check your software, drivers and backups, and tell you honestly whether the problem needs a hands-on repair.
Frequently asked questions
Is it safe to keep using a MacBook that says Service Recommended?
Usually yes, if the battery is not swollen and the Mac behaves normally. The warning is about reduced capacity. Stop using it and get it inspected if you see swelling, heat or sudden shutdowns.
How many cycles does a MacBook battery last?
Apple publishes a rated cycle count per model, and many recent Mac notebooks are designed to retain about 80 percent of capacity at 1000 cycles. Check Apple's current figure for your model, as ratings differ by age and model.
Can I run my MacBook plugged in all the time?
Modern MacBooks manage this reasonably well, and optimised battery charging reduces wear. Heat is the bigger risk. Keep the Mac cool and avoid leaving it at 100 percent in a hot place for long periods.
Does replacing the battery make my MacBook faster?
It restores runtime and removes battery-related throttling or shutdowns. It will not fix slowness caused by a full disk, too little memory or old software. For that, see our guide on speeding up a MacBook.
Should I buy the cheapest replacement battery online?
It is risky. Poor quality cells can swell, hold little charge or fail early. Choose a reputable repairer or supplier that offers a warranty, and avoid unmarked batteries.
