The MacBook Pro 13-inch M2 / M1 / A2289 / A2159 Pure Cobalt OEM replacement battery is a premium-tier 58.2 Wh aftermarket cell that uses Pure Cobalt OEM cell chemistry (Lithium Cobalt Oxide / LCO) — the same chemistry Apple specifies for genuine MacBook batteries engineered to restore 4 MacBook variants to original-spec runtime. In particular, this means accurate macOS battery health reporting (not a misleading 100% on a degraded cell), a voltage discharge curve that matches Apple’s System Management Controller calibration, and the full 1000-cycle / 80% capacity lifespan rather than premature taper at 18 months that cheaper NMC aftermarket cells suffer. In addition, capacity, voltage, watt-hours, and physical dimensions all match Apple’s reference design, so the battery drops into the existing chassis with no shimming and no fit issues. Furthermore, NZ stock, the included screwdriver and adhesive kit, and a 6-month warranty round out the package.
Specifically, this MacBook battery brings five advantages that matter for a trade-grade laptop repair: Pure Cobalt OEM cell chemistry (LCO), accurate macOS battery health reporting, zero-cycle factory-fresh delivery, multi-model fit across the supported MacBook variants, and full NZ logistics with same-day dispatch from local stock. Importantly, the cell ships zero-cycle, which means it has not been charged or discharged before reaching you. As a result, you get the full design lifespan from day one.
| What you get | How it benefits you |
|---|---|
| Pure Cobalt OEM cell chemistry (58.2 Wh) | Specifically, Lithium Cobalt Oxide (LCO) cells from an OEM-tier supplier — the same chemistry Apple specifies. As a result, macOS reports accurate battery health, the voltage discharge curve matches Apple’s SMC calibration, and you get the full 1000-cycle / 80% capacity lifespan rather than premature taper at 18 months. |
| Adhesive and screwdrivers included | Specifically, the pack ships with battery adhesive strips and the Pentalobe P5 plus Torx tools required to open the MacBook bottom case and seat the new cell. As a result, technicians have everything required for the install in one part. |
| Zero-cycle, factory-fresh cell | Indeed, you get the full design lifespan from first charge. Moreover, there is no prior wear and no shelf degradation beyond standard storage. |
| Multi-model fit (4 MacBook variants) | In particular, MacBook Pro 13-inch A2159 (2019 Two Thunderbolt), A2289 (2020 Intel Two Thunderbolt), M1 A2338 (Late 2020), M2 A2338 (2022) all use this same cell. As a result, one part covers your repair stock for the whole group. |
| Supplier part number A2171 | Specifically, this matches the OEM-equivalent part identifier. As a result, trade technicians can confirm fit before ordering. |
| NZ stock, dispatch | Generally, weekday orders ship the same day. In addition, tracked overnight delivery is available nationwide. |
| 6-month manufacturing-defect warranty | Importantly, this is local NZ-backed warranty cover. Furthermore, it is handled directly by GA Tech NZ. |
First, this MacBook A2171 replacement battery fits MacBook Pro 13-inch A2159 (2019 Two Thunderbolt), A2289 (2020 Intel Two Thunderbolt), M1 A2338 (Late 2020), M2 A2338 (2022). The specific Apple model identifiers and EMC numbers covered are: A2159 (2019 EMC 3301), A2289 (2020 Intel EMC 3456), A2338 (M1 2020 EMC 3578, M2 2022 EMC 8162). Apple uses the supplier part number A2171 across these MacBook variants because they share the same chassis dimensions and cell layout.
For context, the A2171 cell rates at 58.2 Wh, 5103 mAh, 11.41 V nominal, and 12.95 V charging cutoff, matching the original Apple cell specification. As a result, this replacement battery restores native-feeling runtime after installation. In practice, customers commonly report that a tired MacBook jumps from a few hours of mixed-use battery life back to a full working day on a single charge after the swap.
In particular, this battery suits three groups of buyers. First, MacBook owners whose original cell has degraded below acceptable runtime and who want to keep using the device. Second, NZ repair shops and trade technicians who need a reliable, local-stocked MacBook battery for fast paid repair work. Third, experienced DIY repairers who already own the precision tools for MacBook disassembly. However, for first-time DIY repairers, GA Tech NZ strongly recommends professional fitting through the in-house repair service because MacBook cell removal requires careful isopropyl alcohol application and a damaged lithium cell is a fire risk.
Typically, a new Li-ion polymer cell retains 80 percent of its design capacity through roughly 1000 full charge cycles for a MacBook-class battery, which works out to three to five years of normal daily use. After that, capacity will begin to taper, and the next replacement window opens. Meanwhile, GA Tech NZ’s 6-month warranty covers manufacturing defects in the first 6 months from delivery, and the cell itself is built to deliver the full Li-ion design lifespan when charged within Apple’s voltage range.
MacBook Pro 13-inch A2159 (2019 Two Thunderbolt), A2289 (2020 Intel Two Thunderbolt), M1 A2338 (Late 2020), M2 A2338 (2022) all use the same physical battery cell with the A2171 supplier part number. Therefore, repair shops and trade technicians can stock one battery part to cover 4 common MacBook repair jobs. This reduces inventory complexity, simplifies parts ordering, and means a single battery in stock can serve any compatible customer MacBook that walks through the door.
Since 2017, GA Tech NZ has supplied spare parts and repair services across New Zealand. Because GA Tech NZ holds the MacBook Pro 13-inch M2 / M1 / A2289 / A2159 Pure Cobalt OEM battery in local stock, weekday orders are dispatched the same day with tracked overnight courier delivery nationwide.

Specifically, this MacBook A2171 replacement battery fits the following MacBook variants and their EMC revisions.
Before ordering, to confirm your MacBook model number, click the Apple menu > About This Mac. The A-XXXX identifier in the More Info / System Report view should match one of those listed above.
The MacBook battery sits beneath the bottom case, bonded to the chassis with strong cell adhesive, and connected via a flex cable to the logic board. Generally, a trained technician completes the full swap in 60 to 120 minutes including bottom case removal, cell adhesive softening, and reseal. For buyers unfamiliar with MacBook disassembly, GA Tech NZ strongly recommends in-house MacBook battery replacement.
First, the supplier holds standard CE Declaration of Conformity (EU Council EMC Directive 2014/30/EU) and FCC Supplier’s Declaration of Conformity (FCC Part 15 Subpart B / ANSI C63.4:2014) for this battery line. In addition, the supplier holds standard lithium-battery transport and safety documentation, including UN38.3 test reports, MSDS, 1.2M drop test, and air transport identification under CNAS-accredited testing. As a result, the battery line ships with the compliance paperwork required for safe NZ courier transit.
Specifically, Pure Cobalt OEM means the cathode is built from Lithium Cobalt Oxide (LiCoO2 or LCO) — pure cobalt rather than the cheaper Nickel-Manganese-Cobalt (NMC) ternary blends used in standard aftermarket cells. In particular, this matters for three reasons. First, LCO is the chemistry Apple specifies for genuine MacBook batteries, so the voltage discharge curve matches Apple’s System Management Controller calibration. As a result, macOS battery health reporting tracks the real capacity accurately rather than showing a misleading 100% on a degraded cell.
Second, LCO delivers higher specific energy density (around 150-200 Wh per kilogram), which means longer runtime per charge cycle. Third, when paired with Apple’s Battery Management System, LCO tracks the 1000-cycle / 80% capacity spec correctly, giving you the full three-to-five-year design lifespan rather than premature taper at 18 months that cheaper NMC aftermarket cells suffer. OEM Original signals these cells are sourced from the same factories that produce Apple’s genuine service replacement batteries.
Specifically, the MacBook A2171 replacement battery is rated at 58.2 Wh, 5103 mAh, 11.41 V nominal, and 12.95 V charging cutoff. As a result, these numbers match the original Apple cell specification, which is why runtime after installation tracks the factory experience closely.
Yes, indeed. Because the cell is zero-cycle and built to Apple’s original capacity specification, a tired MacBook typically returns to a full working day of mixed use after the swap. However, real-world runtime depends on screen brightness, WiFi signal strength, and CPU/GPU workload from background apps.
Generally, a new Li-ion polymer MacBook-class cell retains 80 percent of its design capacity through approximately 1000 full charge cycles. With normal daily use, that works out to roughly three to five years before the next noticeable degradation. Meanwhile, GA Tech NZ’s 6-month warranty covers any manufacturing defects in the first 6 months from delivery.
Specifically, this pack fits MacBook Pro 13-inch A2159 (2019 Two Thunderbolt), A2289 (2020 Intel Two Thunderbolt), M1 A2338 (Late 2020), M2 A2338 (2022). The full Apple A-number and EMC list is: A2159 (2019 EMC 3301), A2289 (2020 Intel EMC 3456), A2338 (M1 2020 EMC 3578, M2 2022 EMC 8162). Therefore, confirm your model number in About This Mac before ordering.
No. The A1989 / A2251 uses the standard-tier A1964 (58 Wh, different cell layout and chemistry) and the 14-inch M1 Pro A2442 uses A2519 (69.9 Wh). The A2171 Pure Cobalt OEM fits the A2159 (2019), A2289 (2020 Intel), and the M1/M2 A2338 13-inch models only.
Yes. The pack includes the battery adhesive strips needed to bond the new cells to the chassis, plus the Pentalobe P5 screwdriver for the bottom case and the Torx driver for the internal screws. Therefore, technicians have everything needed to open the MacBook, remove the old cell, and seat the new battery in one purchase.
Yes, indeed. In fact, GA Tech NZ offers in-house MacBook battery replacement. Generally, the full job takes 60 to 120 minutes in the workshop and includes a final test before handover. In addition, MacBook battery repair is more delicate than phone work because the cells are bonded with strong adhesive that requires isopropyl alcohol softening, so professional fitting significantly reduces the risk of cell puncture or chassis damage.
Generally, weekday orders placed before the dispatch cutoff are sent the same day with tracked overnight courier delivery nationwide. Urban delivery usually arrives the next business day, rural deliveries may take two business days or more.
First, GA Tech NZ provides a 6-month warranty against manufacturing defects on this MacBook Pro 13-inch M2 / M1 / A2289 / A2159 Pure Cobalt OEM replacement battery.
