Your MacBook Pro's battery is no longer keeping pace with its performance. Instead of powering your workday, it’s forcing you to tether to a charger, shutting down unexpectedly, or dying hours before you're finished. When a machine built for mobile power becomes a desktop-only device, your workflow suffers.
If you’re looking for one of the best MacBook service centres for MacBook Pro A3403 battery replacement in Faridabad, Lappy Maker is the choice. We can arrange for a free pickup from your door, have it looked at by our certified technicians, and deliver it. You also get up to a 1-year warranty for peace of mind.
The A3403 is a 14-inch MacBook Pro with M4 Pro that was released in late 2024. Confirm your model first before proceeding with a battery replacement.
| MacBook Pro 16-inch (M4 Pro, 2024) — Battery Specifications | |
|---|---|
| Full Model Name | MacBook Pro 16-inch (M4 Pro, 2024) |
| Model Identifier | Mac16,7 |
| Battery Model | Confirmed at diagnosis |
| Cell Chemistry | Lithium-Polymer (Li-Po) |
| Capacity | 99.6 Wh |
| Voltage | 11.57V |
| Cell Count | 6-cell |
| Rated Charge Cycles | 1,000 |
| Estimated Battery Life | Up to 24 hours |
| Charging | MagSafe 3, 140W included |
To confirm your model: Apple Menu → About This Mac. If the chip shows M4 Pro, the model identifier is Mac16,7; it confirms A3403.
Worth knowing: The A3403 is exclusive to the 16-inch M4 Pro. Although externally identical to the M4 Max 16-inch (A3186, Mac16,5), these models require different battery part numbers.
Follow these steps to assess your battery health and determine if a replacement is necessary:
If you’re unable to work through your usual routine or the battery is acting inconsistently, watch for these signs:
Safety Note: A swollen battery is a safety issue. A 99.6Wh lithium-polymer pack that’s under pressure puts the logic board, trackpad assembly, and display hinge at real risk. If you suspect swelling, stop using it and reach out to Lappy Maker today
If there are multiple signs that the battery has degraded, these reasons could be one of the main causes:
Heat is the primary enemy of lithium-polymer batteries, especially in Faridabad’s 46°C summers. Because the A3403’s cooling system is optimized for the processor, the battery remains exposed to thermal stress, which accelerates cell degradation.
Demanding tasks like video rendering and large builds drain the battery rapidly, often hitting the 1,000-cycle limit in under three years.
Cheap or unverified power adapters often provide inconsistent voltage and poor current regulation. This instability can overheat the battery, damage sensitive control circuitry, and lead to long-term degradation.
Repeatedly draining your battery to empty stresses the cells, making it difficult to maintain a balanced charge. This imbalance leads to erratic battery readings and unexpected shutdowns.
The A3403 uses a large lithium-polymer battery pack secured with stretch-release adhesive strips. Battery replacement here is a more involved process than the 14-inch, and it needs to be done in the right order.
Our experienced technicians do a full software and hardware diagnostic before anything is opened. We check cycle count, charging circuit health, MagSafe port condition, and whether throttling is battery-linked or something else.
We physically verify the model identifier (A3403), EMC number (8895), and system identifier (Mac16,7) before selecting the replacement.
We select an OEM battery matched to the A3403's confirmed capacity (99.6Wh) and cell chemistry (Li-Polymer). We never use generic packs, as a non-spec replacement produces wrong health readings and disrupts charge management.
We remove the bottom cover and carefully shift the trackpad aside to access the battery adhesive. We release the strips at a precise, low angle for safety. After safely disconnecting the old battery, we install the new unit, refit the trackpad, and reassemble the chassis.
We do a full charge cycle after replacement and verify maximum capacity in macOS, charge speed at MagSafe, thermal behaviour and percentage stability.
We check battery health, trackpad, keyboard, display, all three Thunderbolt 5 ports, HDMI 2.1, SD card slot, MagSafe connector, headphone jack, and chassis alignment before it leaves the bench.

The A3403 is a recent machine, so parts availability at the time of booking is a big factor. Anything flagged during diagnosis beyond the battery gets communicated before work starts. At Lappy Maker, a MacBook Pro A3403 battery replacement price is around ₹10,999 - ₹22,500.
The A3403 (M4 Pro) and A3186 (M4 Max) share the same chassis and battery capacity. Here's a reference across the current and recent 16-inch MacBook Pro lineup:
| 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 prices are estimates. Final cost is confirmed after diagnosis. Includes battery, fitting, 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.
We charge up to 50% less than authorised Apple service centres, and that's not because we're skimping on parts or skipping steps. Same quality, lower price.
Every repair is handled by technicians who know Apple silicon machines. The A3403's trackpad-first disassembly, adhesive sequencing, SMC battery integration - this is familiar territory for our team.
We don't use generic or cheap aftermarket batteries. Every replacement is matched to your model's confirmed capacity, voltage, and cell chemistry so macOS reads it correctly and charge management works as it should.
If we can't fix your MacBook Pro A3403, you pay nothing. No diagnosis charge, no handling fee, no cost for pickup or return. Zero.
Every battery replacement comes with up to a 1-year warranty on the part and the fitting. You're not just getting the repair but also the assurance that it holds.
A degraded battery progressively throttles your M4 Pro’s performance, turning your powerful, mobile MacBook into a stationary, power-dependent device. Waiting to replace it only compounds these issues, as performance drops without lowering the eventual repair cost.
Swollen batteries are a major risk for the A3403’s large 99.6Wh cell. As it expands, it puts dangerous pressure on the logic board, trackpad, and display hinge. While a timely replacement is a predictable cost, ignoring it can lead to expensive multi-component damage that may render the device irreparable.
Follow these steps and ensure you follow them to effectively make your newly replaced battery last:

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, we provide free doorstep pickup and delivery across Faridabad. Our agent can come to your location, you sign off on internal components, and the machine is returned after the repair.
Estimates fall between ₹10,999-₹22,500. This includes an OEM battery, fitting, testing, and up to 1-year warranty.
The A3403 uses a 99.6Wh lithium-polymer battery. The specific part number is verified on-unit during diagnosis rather than being selected based on cross-model assumptions.
Go to Apple Menu → System Settings → Battery → click (i) next to Battery Health. For cycle count and full technical data, go to Apple Menu → About This Mac → System Report → Power.
Yes. All Lappy Maker battery replacements come with up to 1-year warranty covering the battery and the fitting.
Most repairs are completed the same day, subject to parts availability. The 16-inch chassis requires the trackpad to be removed before accessing the battery adhesive, so the process takes slightly longer than smaller MacBook models.
Yes. Battery replacement does not affect the SSD, so your files, apps, and settings remain unaffected. We recommend taking a current backup before any hardware repair.
If your A3403 is still covered by Apple's one-year limited warranty or AppleCare+, it is best to check with Apple first. We use OEM-quality parts and provide our own warranty of up to 1 year.
They share the same 99.6Wh battery capacity, but the A3186 is a different model number with a different system identifier (Mac16,5 vs Mac16,7).
