That aging 2015 MacBook Pro with the legendary MagSafe 2 port, glowing logo, and comfortable keyboard still runs your daily apps, but the battery warning in the menu bar is now a permanent fixture. The cycle count has passed 1,000, the trackpad clicks feel sluggish because the swollen battery is pressing up from underneath, and you’re tethered to the charger just to finish a single work session. Unlike modern soldered-in batteries, the 2015 models use a user-replaceable connector — so a fresh cell genuinely restores the portability and performance you bought the laptop for.
I’m Min — the co-founder and writer behind Gadgets Feed. Over many hours of research comparing capacity ratings, cell grades, voltage tolerances, and real-world cycle lives across the third-party replacement ecosystem, I’ve parsed which batteries actually match Apple’s original Ah spec and which ones swell after three months.
Making the right call on a 2015 macbook pro battery replacement means weighing capacity against safety certifications, checking whether the included toolkit actually fits the pentalobe and tri-wing screws on your exact model year, and confirming the battery is recognized by macOS without error prompts.
How To Choose The Best 2015 MacBook Pro Battery Replacement
Choosing the wrong battery for your 2015 MacBook Pro can lead to trackpad failure, random shutdowns, or a battery that macOS refuses to recognize. The 2015 Retina models use two distinct battery form factors — the 13-inch A1502/A1582 and the 15-inch A1398/A1618 — each with different voltage and capacity specs. A few key checks separate a seamless restoration from a frustrating return.
Match Your Model Number and Voltage
The 13-inch 2015 MacBook Pro (A1502) uses an 11.42V battery with a nominal capacity of 74.9Wh, while the 15-inch version (A1398) requires an 11.36V battery rated at 99.5Wh. Installing the wrong voltage can trigger kernel panics or a “Service Battery” warning. Always verify your model identifier (MacBookPro12,1 for 13-inch, MacBookPro11,4 or 11,5 for 15-inch) in “About This Mac” before purchasing.
Grade A Cells and Swelling Resistance
The lithium-ion cells inside these replacements vary in quality. Grade A cells undergo tighter manufacturing tolerances, meaning they are less likely to swell after 200-300 cycles. Swelling not only deforms the unibody chassis but also presses against the trackpad cable, ruining click feel. Look for explicit “Grade A” labeling and safety certifications (CE, FCC, RoHS) to ensure the battery includes overcharge, over-discharge, and short-circuit protection.
Included Tools and Installation Complexity
The 2015 MacBook Pro battery is glued into the upper case with aggressive adhesive strips. A good replacement kit includes P5 pentalobe and T5 Torx screwdrivers, plastic spudgers, and sometimes chemical adhesive remover. Without the correct tools, you risk stripping the tiny screws or damaging the logic board during removal. Kits that provide a printed manual or QR code linking to a video tutorial reduce the chance of bending the flex cables.

In-Depth Reviews
1. iFixit A1398 A1618 Battery for MacBook Pro 15″ Retina (Mid 2015) – Repair Kit
The iFixit A1618 kit is the gold standard for 2015 MacBook Pro 15-inch battery replacements because iFixit includes every consumable — pentalobe and Torx screwdrivers, spudgers, tweezers, solvent, safety glasses, and fresh adhesive strips — in a single box. The battery itself is rated at 8800mAh and 99Wh, matching the OEM capacity for the A1398 Mid 2015 model, so macOS reports the correct cycle count and health percentage from the first boot. Unlike generic third-party packs that sometimes ship with mismatched flex cables, iFixit’s unit is identical to the Apple service part in connector position and thickness.
Installation requires patience because the old adhesive is notoriously aggressive; the included solvent helps soften the glue, but users still report spending 20-30 minutes working the old cells free without bending the logic board. The kit’s printed manual is minimal, and the QR code linking to a YouTube tutorial is less helpful when the laptop itself is dead. After three charge cycles, the battery reports around 8584mAh actual capacity, which is 99.8% of the rated spec — excellent real-world retention.
This isn’t the cheapest option, but the reliability premium and the fact that iFixit backs it with a one-year warranty against swelling and capacity degradation make it the safest long-term choice for a 15-inch machine you plan to use daily. If you want absolute peace of mind and are comfortable with a moderately complex DIY job, this kit delivers a result as close to a genuine Apple repair as any third-party part can.
Why it’s great
- Complete kit includes every tool and adhesive needed
- Matches OEM capacity exactly (99Wh / 8800mAh)
- One-year warranty against defects and swelling
Good to know
- No paper manual — video guide requires a second device
- Adhesive removal is time-consuming without extra solvent
2. GingePro Battery Replacement for MacBook Pro 15-inch A1398 (Late 2013, Mid 2014, Mid 2015) A1494/A1618
The GingePro A1494/A1618 replacement is aimed at 15-inch MacBook Pro owners who want a reliable cell at a mid-premium price point, just below the iFixit kit. Rated at 8700mAh and 98Wh with a nominal 11.26V output, it covers the Late 2013, Mid 2014, and Mid 2015 A1398 models — broad compatibility if you verify your machine’s model year via the serial number. Users report that random shutdowns and the “Service Battery” warning disappear immediately after installation, and the battery holds 5-6 hours on light productivity workflows like writing and web browsing.
The included toolkit covers P5 pentalobe and T5 Torx bits, but the adhesive removal process benefits from a drop of isopropyl alcohol to loosen the old cells. One reviewer noted that lifting the trackpad ribbon cable before pulling the adhesive prevents accidental damage to the haptic feedback sensor. The battery sits flush against the upper case without bulging, and macOS recognizes it without any error prompts on first boot.
Some units show a slight cosmetic gap near the screw hole alignment — the rubber bumpers on the cells are slightly taller than OEM, but this does not affect performance or safety. The 12-month replacement warranty is comparable to other premium third-party options, and customer support is responsive according to buyer feedback. This is a strong mid-premium choice if the iFixit kit is out of stock or you need compatibility with multiple 15-inch model years.
Why it’s great
- Restores 5-6 hours of real-world battery life
- macOS fully recognizes health and cycle count
- Broad year compatibility (Late 2013 to Mid 2015)
Good to know
- Screw hole alignment may be slightly off on some units
- Adhesive removal requires careful technique or solvent
3. NDWQGFS A1582 Battery for MacBook Pro 13 Inch Retina (Early 2015, Mid 2014, Late 2013) A1502 A1493
The NDWQGFS A1582 battery is one of the best mid-range options for the 13-inch 2015 MacBook Pro (A1502), delivering 6559mAh at 11.42V — virtually identical to the original Apple spec. The cells are Grade A certified with CE/FCC/RoHS marks, and the built-in protection circuit guards against overcharge, short-circuit, and overheating. macOS reports the battery health and cycle count correctly without error prompts, and users consistently get 8-10 hours on mixed workloads of browsing, office apps, and video playback.
The kit includes P5 pentalobe and T5 Torx screwdrivers, plus plastic opening tools that make the 15-minute installation claim realistic for anyone who has watched a single MacBook battery guide. The adhesive strips are pre-cut and align well with the battery wells in the upper case, reducing the risk of the battery shifting during placement. One reviewer experienced a swollen battery on the first unit, but the seller immediately sent a replacement with good customer service — a reminder to test the unit immediately upon arrival.
Rated for 500+ recharge cycles, this battery should last 2-3 years under normal daily use. The 12-month warranty and 30-day money-back guarantee provide solid buyer protection at this price tier. For 13-inch owners looking for a drop-in replacement that works out of the box without fiddling, this is the most practical and cost-effective choice.
Why it’s great
- Matches OEM capacity and voltage exactly
- Full toolkit included with no extra purchases needed
- 8-10 hour real-world battery life
Good to know
- Rare defect reports; test immediately and use warranty
- Not compatible with 15-inch A1398 models
4. ASUNCELL A1502 A1582 Laptop Battery for MacBook Pro 13 inch Retina (Early 2015, Mid 2014, Late 2013)
The ASUNCELL A1582 is a direct competitor to the NDWQGFS battery for the 13-inch Retina MacBook Pro, offering the same 74.9Wh capacity at 11.42V but with a slightly different cell layout (6-cell configuration). Users report that macOS recognizes the battery immediately on MacBookPro12,1 machines, displaying the correct watt-hour rating without “Service Battery” warnings. The rated operational time of 1.5-3 hours is conservative — real-world mixed usage actually yields closer to 4-5 hours, which is a strong improvement over a worn-out original.
The installation kit includes P5 pentalobe screwdrivers and plastic pry tools, though the T5 Torx driver is absent in some packages, so you may need your own for the battery connector bracket. The adhesive strips are pre-applied and provide good grip without being overly aggressive, making removal easier if you ever need to replace this battery again. One reviewer noted that the battery fit was snug in the A1502 chassis with no bulging or trackpad interference.
ASUNCELL backs this with a one-year warranty and 24/7 email support, and the battery carries UL/CE/FCC/RoHS certifications. The main trade-off compared to the NDWQGFS is slightly shorter reported runtime in heavy gaming or video editing scenarios. For basic office work, web browsing, and streaming, this is a perfectly adequate and reliable mid-range option that won’t break the budget.
Why it’s great
- macOS recognized immediately with no error prompts
- Snug fit without trackpad interference
- UL/CE/FCC/RoHS safety certifications
Good to know
- Rated runtime is conservative; real-world closer to 4-5 hours
- Some kits missing T5 Torx bit for bracket screws
5. NDWQGFS A1398 A1618 Laptop Battery Replacement for MacBook Pro 15 inch Retina Late 2013 Mid 2014 Mid 2015 Early 2015
This NDWQGFS battery targets the 15-inch A1398 MacBook Pro, delivering 8755mAh at 11.36V for a total of 99.5Wh — essentially matching the OEM spec. It covers Late 2013 (EMC 2674), Mid 2014 (EMC 2745), and Mid 2015 (EMC 2909/2910) models, but it is explicitly not compatible with the Mid 2012 or Early 2013 A1398 machines. The Grade A cells include smart protection against overcharge, over-discharge, and short circuits, which is critical for a high-wattage battery that generates more heat during heavy loads.
Installation mirrors the 13-inch NDWQGFS kit: included P5 pentalobe and T5 Torx drivers, plus plastic spudgers. The adhesive is strong, and reviewers recommend using a plastic card or iOpener to separate the old cells without puncturing the pouch. One reviewer noted that the first battery arrived with a slight bulge that caused the trackpad to stick, but the seller dispatched a replacement same-day with no hassle — good customer service but a reminder to inspect the battery immediately on delivery.
Real-world runtime is around 3-3.5 hours of mixed use, which is typical for a refurbished 15-inch battery on a machine with a discrete GPU. The 12-month replacement warranty and 30-day money-back guarantee match the 13-inch version. If you want the same proven value proposition as the 13-inch NDWQGFS but in a 15-inch form factor, this is the affordable pick.
Why it’s great
- Almost identical capacity to OEM 99.5Wh spec
- Full safety protections against overcharge and short circuit
- Includes correct pentalobe and Torx tools
Good to know
- Inspect immediately; some units arrive with slight bulge
- 3-3.5 hour runtime is average for 15-inch discrete GPU machines
6. SeaPlant A1502 Battery Replacement for MacBook Pro 13-inch A1502 (Early 2015, Mid 2014, Late 2013) A1493/A1582
The SeaPlant A1502 battery stands out because it pushes the capacity slightly beyond the OEM spec — 7000mAh at 11.34V for a total of 79.4Wh, compared to Apple’s original 6559mAh / 74.9Wh. That extra 6% capacity translates to roughly 30-45 minutes more runtime on a single charge, which is noticeable when you’re in back-to-back meetings or a long flight. The battery is built with the latest high-capacity cell technology and includes overcharge, overload, short-circuit, and temperature variation protection.
Installation is straightforward with the included pentalobe and Torx tools, but some users report that the screw hole alignment is off by about 3mm on one corner — leaving that screw out or carefully slotting the hole with a drill bit resolves the issue. The battery ships with roughly 32% charge, and reviewers testing full-screen YouTube at max brightness got 1 hour 48 minutes, which aligns with the rated capacity under heavy load. In normal mixed use, reviewers report getting a full workday of productivity.
The main drawbacks are slight cosmetic differences from the OEM finish and the fact that some users experienced a gradual capacity loss when the MacBook was left in an improper sleep state. The seller, SeaPlant, has a reputation for proactive customer service — offering refunds if the product is faulty. If you want the maximum possible runtime from a 13-inch replacement and are willing to tolerate a minor alignment quirk, this is the high-capacity champion.
Why it’s great
- Above-OEM capacity (79.4Wh vs stock 74.9Wh)
- Extended runtime for productivity and media
- Responsive customer support from SeaPlant
Good to know
- Screw hole alignment may be slightly off on some units
- Capacity can degrade if sleep settings are misconfigured
7. ASUNCELL A1398 Laptop Battery Replacement, EMC 2745 2881 2909 2910, fits A1494 A1618
The ASUNCELL A1618 is the entry-level gateway to reviving a 15-inch 2015 MacBook Pro, offering the same 8755mAh at 11.36V as the NDWQGFS version but at a slightly lower cost. It covers the A1398 Late 2013, Mid 2014, and Mid 2015 models, and like all batteries in this class, requires you to verify your specific model number via “About This Mac” before ordering — the Mid 2012 and Early 2013 A1398 use a different battery shape. The Grade A lithium-polymer cells are UL/CE/FCC/RoHS certified and include overheat, short circuit, and overload protection.
Installation is identical to other 15-inch kits: remove the lower case, disconnect the old battery, carefully peel the adhesive strips, and drop in the new pack. Users report that macOS recognizes the battery immediately, and the cycle count resets to zero. One reviewer noted that after months of use, the battery held a charge well — dropping to 77% after one hour of gaming over GeForce NOW, then lasting over 4 hours of HD video streaming. That’s solid real-world performance for a 15-inch machine with a discrete GPU.
The kit includes pentalobe and Torx screwdrivers, though the construction quality of the tools is basic — a magnetized driver would be an upgrade. The battery itself is lightweight at 300 grams, reducing overall laptop weight compared to older swollen cells. The one-year warranty covers defects, but the seller’s responsiveness to warranty claims is less documented than iFixit’s. For a budget-conscious 15-inch repair that still delivers grade-A cells and full safety certifications, this is the right starting point.
Why it’s great
- Grade A lithium-polymer cells with full safety certifications
- macOS recognized immediately with correct cycle count
- Lightweight construction (300g)
Good to know
- Basic screwdriver tools could be better quality
- Warranty support responsiveness is less proven than premium brands
