The iPhone 14 Plus replacement battery is a high-quality 4325 mAh aftermarket cell engineered to restore your iPhone 14 Plus to original-spec runtime. In particular, capacity, voltage, watt-hours, and physical dimensions all match Apple’s reference design, so the battery drops into the existing chassis with no shimming, no fit issues, and no surprises at boot. In addition, NZ stock, professional-grade build, and a 6-month warranty round out the package.
This iPhone 14 Plus replacement battery brings four advantages that matter for a daily-driver repair: an original-spec 4325 mAh cell that restores factory-equivalent runtime, a Texas Instruments battery management IC for safe charging and discharge protection, an install workflow matched to the iPhone 14 Plus’s service profile, and full NZ logistics with same-day dispatch from local stock. The cell ships zero-cycle, which means it has not been charged or discharged before reaching you, so you get the full design lifespan from day one.
| What you get | How it benefits you |
|---|---|
| Original-spec 4325 mAh capacity | All-day runtime that tracks the factory cell, with no drop-off in standby time. |
| Texas Instruments battery management IC | Proven charging chemistry with overcharge, over-discharge, and short-circuit protection built into the pack. |
| Zero-cycle, factory-fresh cell | Full design lifespan from first charge. No prior wear, no shelf degradation beyond standard storage. |
| Battery adhesive pre-installed | Faster install, cleaner workspace, no separate adhesive strips to source or apply. |
| Battery Health percentage shows on iOS 18 and current iOS releases | Real percentage displays in Settings > Battery > Battery Health after install. Parts & Service History labels the cell as “Unverified” (informational only). |
| NZ stock, 2pm dispatch cutoff | Weekday orders placed before 2pm ship the same day with tracked overnight delivery nationwide. |
| 6-month manufacturing-defect warranty | Local NZ-backed warranty cover, handled directly by GA Tech NZ. |
| iOS reports | Why | What it means for you |
|---|---|---|
| Settings > Battery > Battery Health: displays a real percentage on iOS 18 and every later iOS release | Apple changed the display behaviour in iOS 18 to show the percentage for aftermarket cells | You can monitor battery health the same way you did with the factory cell. |
| Settings > General > About > Parts and Service History: “Unverified” | The cell does not carry Apple’s serialised identifier chip | Informational label only. Charging, runtime, and longevity are not affected. |
| Charging, runtime, and longevity | The cell operates on standard Li-ion chemistry matched to Apple’s design | Tracks the factory cell experience after correct installation. |
First, this iPhone 14 Plus replacement battery fits Apple iPhone 14 Plus (model numbers A2632, A2885, A2886, A2887, A2888). The 14 Plus uses its own cell, separate from the 14, 14 Pro, and 14 Pro Max. Once the battery is seated and connected, the cell uses standard Li-ion chemistry matched to Apple’s reference design, so the iPhone 14 Plus powers on, charges, and holds charge the same way it did with the factory cell.
For context, Apple’s original iPhone 14 Plus cell rates at 4325 mAh, 3.86 V nominal, 4.47 V charging cutoff, and 16.7 Wh. As a result, this replacement battery matches every one of those numbers, which is what makes the runtime feel native after installation. In practice, customers commonly report that a tired iPhone 14 Plus jumps from a few hours of standby back to a full day on a single charge, which is the result of swapping a worn cell back to fresh, factory-spec capacity.
In particular, this battery suits three groups of buyers. First, iPhone 14 Plus owners whose original cell has degraded below acceptable runtime and who want to keep using the device for another couple of years. Second, NZ repair shops and trade technicians who need a reliable, local-stocked iPhone 14 Plus battery for paid repair work. Third, experienced DIY repairers who already own the precision tools and have replaced a screen or battery before. However, for first-time DIY repairers, GA Tech NZ offers professional fitting through the in-house repair service to remove the risk of damaging surrounding flex cables.
Typically, a new Li-ion cell retains 80 percent of its design capacity through roughly 500 full charge cycles, which works out to two or three years of normal daily use. After 500 cycles, 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.
Since 2017, GA Tech NZ has supplied spare parts and repair services across New Zealand. Because GA Tech NZ holds the iPhone 14 Plus battery in local stock, weekday orders placed before 2pm ship the same day with tracked overnight courier delivery nationwide. Generally, urban delivery sits at $8 and rural at $13, with most orders landing the next business day. In addition, buyers who want a fitted result can book in-house iPhone 14 Plus battery replacement. Meanwhile, for complementary parts and tools, browse the iPhone parts and repair tools categories. Finally, to confirm Apple-published specifications for the iPhone 14 Plus, see the Apple iPhone 14 Plus technical specifications or the iPhone 14 Plus listing on GSMArena.

Specifically, this replacement battery fits the following Apple iPhone 14 Plus model numbers. The 14 Plus uses its own cell, separate from the 14, 14 Pro, and 14 Pro Max.
Before ordering, to confirm your iPhone 14 Plus model number, open Settings > General > About on your iPhone, then scroll down to Model Number. If the number starts with M or N, tap it once to reveal the A-number.
Generally, the iPhone 14 Plus battery sits beneath the display, secured by adhesive strips and connected via a flex cable to the logic board. Typically, a trained technician completes the full swap in 20 to 30 minutes. Therefore, GA Tech NZ offers in-house iPhone 14 Plus battery replacement for buyers unfamiliar with iPhone disassembly.
First, the supplier holds a CE Declaration of Conformity (NCT25007416XE1-1, EU Council EMC Directive 2014/30/EU) and an FCC Supplier’s Declaration of Conformity (NCT25007419XE1-1, FCC Part 15 Subpart B / ANSI C63.4:2014) for this battery line, with this iPhone model explicitly named in the multi-model coverage list, both issued by NCT Testing Technology under CNAS L8281 accreditation. 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, the iPhone 14 Plus replacement battery is rated at 4325 mAh, 3.86 V nominal, 4.47 V charging cutoff, and 16.7 Wh. As a result, these numbers match the original Apple cell specification exactly, 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 iPhone 14 Plus typically returns to all-day standby and full-day mixed use after the swap. However, real-world runtime depends on screen brightness, mobile signal strength, and background app activity.
Generally, a new Li-ion cell retains 80 percent of its design capacity through approximately 500 full charge cycles. With normal daily use, that works out to roughly two to three 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 iPhone 14 Plus A2632, A2885, A2886, A2887, A2888. The 14 Plus uses its own cell, separate from the 14, 14 Pro, and 14 Pro Max. Therefore, confirm your A-number in Settings > General > About before ordering.
First, on iOS 18 and every iOS release after (including the current iOS version iPhone 14 Plus runs), Settings > Battery > Battery Health displays a real percentage for this replacement battery. In Settings > General > About > Parts and Service History, the battery is labelled “Unverified” because the cell does not carry Apple’s serialised identifier. In particular, this label is informational only. By contrast, on older iOS versions (iOS 13 through 17), Apple hid the percentage behind a Service notice; in addition, Apple changed this behaviour in iOS 18. Ultimately, the battery itself charges, discharges, and powers the iPhone 14 Plus the same way as the factory cell, regardless of the label.
No. The iPhone 14 Plus uses its own 4325 mAh cell. The standard iPhone 14 carries a 3279 mAh cell and the 14 Pro Max uses a 4323 mAh cell in a different physical size, despite the close capacity number.
Yes, indeed. In fact, GA Tech NZ offers in-house iPhone 14 Plus battery replacement. Generally, the full job takes 20 to 30 minutes in the workshop and includes a final test before handover.
Generally, weekday orders placed before 2pm dispatch the same day with tracked overnight courier delivery nationwide. In addition, urban delivery is $8 and rural is $13. As a result, most orders arrive the next business day.
First, GA Tech NZ provides a 6-month warranty against manufacturing defects on this iPhone 14 Plus replacement battery. However, the warranty does not cover physical damage, installation errors, or water damage. In addition, GA Tech NZ accepts change-of-mind returns on unopened parts in new unused condition within 7 days of receipt under the GA Tech NZ terms and conditions.
