A MacBook Pro 16-inch M4 Pro is not a machine you expect to babysit. Yet, here you are constantly watching the percentage fall faster than it should, getting cut off mid-task or simply never unplugging. When a laptop that’s built for all-day performance stops functioning without a power cable nearby, something has gone wrong with the battery.
For MacBook Pro A3403 battery replacement in Ghaziabad, Lappy Maker arranges free doorstep pickup from anywhere in the city. Our certified technicians carry out the repairs at our Nehru Place or Gurgaon service centre and deliver it back to you - with an assured warranty of up to 1 year.
The A3403 is the 16-inch MacBook Pro with M4 Pro. It was released in late 2024. Be sure to confirm this before a replacement is placed.

To confirm your specific model, you can check ‘About This Mac’ under the Apple Menu. If the chip name says M4 Pro with model identifier Mac 16,7, it confirms A3403.
Apple has made it extremely easy to check the status of battery health on most of their devices.
If your 16-inch MacBook M4 Pro can no longer get through a routine workday or has abnormal battery behaviour, these are the specific signs that point to a problem with the battery:
Safety Hazard: The A3403 carries a 99.6 Wh Li-Po pack. When under physical pressure, the logic board, trackpad assembly, display hinge, etc. are at serious risk. If you notice any sign of swelling, stop using the machine immediately and contact Lappy Maker .
When several symptoms appear together, one or more of these underlying causes is typically behind them.
Li-Po batteries' biggest enemy is heat. Ghaziabad’s summers can easily push ambient temperatures well above 40°C. While the A3403’s active cooling helps the processor a bit, the battery still remains exposed to thermal stress, which can accelerate cell degradation.
The M4 Pro is very good at handling demanding tasks such as video rendering, large compilations, intensive creative work, and so on. But running it hard daily accumulates charge cycles faster than lighter use would.
Using cheap or unverified adapters can deliver inconsistent voltage and poor current regulation. This instability forces the battery management system to compensate continuously, which causes degradation.
Regularly draining the battery to near zero stresses the cells, which makes it harder to maintain a balanced charge across them. This can cause erratic readings and shutdowns that occur well above zero percent.
Replacing the battery on the MacBook Pro A3403 requires precision and an experienced hand to access the battery with the correct sequence.
Our team runs a complete software and hardware diagnostic before we open anything. We check the cycle count, charging circuit health, MagSafe port condition, etc and confirm whether other symptoms are battery-linked.
We then physically verify the model identifier (A3403), EMC number (8895), and system identifier (Mac16,7) before selecting a replacement. This is to prevent a wrong part fit with the A3186, which shares the same chassis.
An OEM battery that’s matched to the A3403’s confirmed capacity (99.6Wh) is selected. We do not use a generic or different spec as the replacement, which can cause inaccurate health readings and disrupt charge management.
The base cover is removed and the trackpad carefully repositioned to access the adhesive strips, which are released at a precise low angle. The old battery is safely disconnected, the new unit installed, the trackpad refitted, and the chassis reassembled in the correct sequence.
After a successful installation, we will verify maximum capacity in macOS, confirm the condition reads Normal, check charge speed with MagSafe and monitor thermal behaviour under load, and watch for any percentage instability.
Battery health, trackpad, keyboard, display, all three Thunderbolt 5 ports, HDMI 2.1, SD card slot, MagSafe connector, headphone jack, and chassis alignment are all checked before the machine leaves the bench.

The A3403 is a recent model, and parts availability at the time of booking is a meaningful factor in both price and turnaround. Anything identified during diagnosis beyond the battery is communicated before work begins. MacBook Pro A3403 battery replacement in Ghaziabad is estimated at ₹10,999 - ₹22,500.
Estimated Cost — A3403 & Related 16-inch MacBook Pro Models
| Model | Chip | Year | Battery | Est. Replacement Cost |
|---|---|---|---|---|
| A3403 | M4 Pro | 2024 | 99.6Wh | ₹10,999 – ₹22,500 |
| A3186 | M4 Max | 2024 | 99.6Wh | ₹10,999 – ₹22,500 |
| A2991 | M3 Pro / M3 Max | 2023 | 99.6Wh | ₹10,999 – ₹20,500 |
All figures are starting estimates. Final cost is confirmed in writing after diagnosis and includes the battery, fitting, full testing, and up to a 1-year warranty.
When considering a service centre for a battery replacement, choosing a reliable service provider ensures both safety and long-term performance.
Lappy Maker has our own trained technicians, allowing us to charge much less than other authorised Apple service centres. Quality spares at lower cost with no shortcuts in the process.
Every repair is handled by technicians trained specifically on Apple silicon machines. The A3403's trackpad-first disassembly, adhesive sequencing, and SMC battery integration are well within their scope.
We don't use generic aftermarket batteries. Every replacement is matched to your model's confirmed capacity, voltage, and cell chemistry so macOS reads it correctly and charge management behaves as it should.
If we can't fix your MacBook Pro A3403, you pay nothing — no diagnostic charge, no handling fee, no pickup or delivery cost.
Every eligible battery replacement comes with up to a 1-year warranty on the part and the fitting. The repair comes with the assurance that it holds.
A degraded battery in the A3403 progressively throttles the M4 Pro chip to match what the cells can safely supply. A machine built for serious, sustained performance starts behaving like something considerably more ordinary. Runtime keeps shrinking, shutdowns become more frequent, and eventually the laptop only works when plugged in.
The swelling risk is more serious on the 16-inch than smaller models. A 99.6Wh lithium-polymer cell expanding under pressure puts the logic board, trackpad assembly, and display hinge under sustained stress. What starts as a predictable, fixed battery replacement can escalate into multi-component damage that may not be fully reversible. Getting ahead of it is always the lower-cost path.
Taking steps to preserve your MacBook’s battery health is critical for the long-term proper functioning of the device

It was a wonderful experience getting my MacBook screen repair at Lappy maker. They are very professional when it comes to service. I was pleasantly surprised by their thorough knowledge of the product. They are honest and eager to help out. And I am happy I found an excellent place to get my Apple MacBook fixed at a competitive price and with quality work. I wish them all the best in their endeavors.
Awesome experience, genuine Mac repair service, really helpful staff , they are so ground to earth and polite when they speak and discuss the issue. They will explain everything and even the price is genuine. Overall I really recommend to anyone who wants to repair the MacBook - 5 star rated
We were struggling to MacBook issue, after visiting other repairing store but luckly found Lappy Maker. Now our Mac is completely fine! Thanks!
My Macbook Air was having frequent screen issue. I called these guys up and the engineer was at my place immediately. Took 3 days to figure out the problem of a power circuit which needed to get redone.I was sceptical initially as the costing was coming too much which was very close to the value of laptop. However Mr. Santosh who was the engineer repairing the MacBook had a great attitude of never giving up. My Laptop is working fine again and hopefully it would remain like this for some time. I'm happy with the entire experience and pricing. Would recommend to consult them for all mac laptop related problems.
Yes. Lappy Maker provides free doorstep pickup and delivery across Ghaziabad. Our agent comes to your location, handles the component sign-off before anything is opened, and returns the repaired machine once the work is complete.
The estimate falls between ₹10,999 and ₹22,500, covering the OEM battery, fitting, testing, and up to a 1-year warranty. The confirmed price is provided in writing after diagnosis, before any work starts.
The A3403 uses a 99.6Wh lithium-polymer battery. The specific part number is verified on-unit at diagnosis — we don't select replacements based on cross-model assumptions, since Apple's part numbers for recent models can differ from predecessors with similar capacities.
Apple Menu → System Settings → Battery → click (i) next to Battery Health. For cycle count and the full technical breakdown: Apple Menu → About This Mac → System Report → Power.
Yes. All eligible Lappy Maker battery replacements come with up to a 1-year warranty covering both the replacement part and the fitting.
Most replacements are completed the same day, subject to parts availability. The 16-inch chassis requires the trackpad to be repositioned before the battery adhesive can be accessed, so the process takes slightly longer than on smaller MacBook models.
Yes. Battery replacement doesn't touch the SSD or any stored data. Your files, applications, and settings remain unaffected throughout. A current backup before any hardware work is still good practice.
If your A3403 is still within Apple's one-year limited warranty or covered by AppleCare+, verify that first. For machines outside that coverage, independent repair doesn't introduce risks beyond the repair itself. We use OEM-quality parts and back the work with our own up to 1-year warranty.
Both models share a 99.6Wh capacity, but the A3186 carries a different model number and system identifier (Mac16,5 vs Mac16,7). We verify the part number on-unit before any replacement is selected.
