Descripción del Producto
The Apple Watch Ultra 2 (2023) is a different category of device from the standard Apple Watch lineup — 49mm titanium case, rated to 100m water resistance (EN 13319 diving standard), dual-frequency GPS (L1 + L5), 86dB emergency siren, and a 60-hour battery life in Low Power Mode. The battery reflects this: P/N A2956, rated at 564mAh / 3.86V — the largest cell Apple has put in a Watch, nearly double the capacity of the standard Series 9.
The repair profile for Ultra 2 is also different. The titanium case is machined to tighter tolerances than aluminum, and the Action Button adds a second mechanical interface point to manage during disassembly. The display adhesive is the same heat-activated system as standard Watch models, but the case geometry leaves less margin for tool slippage. Repair shops doing Ultra 2 battery work are typically specialist technicians, not general Apple repair techs — and the battery they source needs to be exactly to spec, because a comeback on a $799+ device is a significant cost event.

Características y ventajas
✅ 🔋 564mAh — Largest Apple Watch Cell, Precision-Matched to Titanium Enclosure
At 564mAh, this is the highest-capacity battery Apple uses in any Watch. The titanium case machined to EN 13319 dive standards has tighter internal clearances than aluminum Watch cases — dimensional tolerance at ±0.1mm is not optional. A cell even 0.2mm over spec prevents the display from re-seating and compromises the 100m water resistance seal. Our cells are individually dimensioned and verified before shipment.
✅ 🛰️ Dual-Frequency GPS and Siren Load — Stable High-Current Delivery Required
Ultra 2’s L1+L5 dual-frequency GPS and 86dB emergency siren are peak-current draws that standard Watch batteries are not rated for. The A2956 cell is specified to handle the Ultra’s peak current profile without voltage collapse — a sub-grade cell will cause GPS dropout during route navigation or siren activation failure under load. These are not abstract concerns for the Ultra’s target user base, which includes trail runners, mountaineers, and divers.
✅ 👆 Double Tap and Action Button — Both Mechanical and Sensor Interfaces Preserved
Ultra 2 adds the Action Button as a second hardware interface beyond the Digital Crown. Neither the Action Button nor Double Tap gesture requires battery-side hardware — both are preserved with any correctly installed replacement. The battery connector must seat correctly to avoid Action Button or crown responsiveness issues post-reassembly, which is a technician procedure variable, not a battery spec variable.
✅ 🏭 OEM Options for Specialist Repair Distributors
Custom labeling and retail packaging from 200 pcs. The Ultra 2 repair segment is smaller in volume than standard Watch series but higher in per-repair value — shops doing Ultra 2 work charge a premium, and the battery cost is a smaller percentage of total job revenue. For distributors targeting the premium smartwatch repair channel, A2956 is a high-margin SKU with limited supplier competition compared to standard Watch batteries.

Preguntas frecuentes
Q1: Is the Apple Watch Ultra 2 battery the same as the Ultra 1st Gen?
A: No. Apple Watch Ultra (2022, A2684) uses battery P/N A2652 at 542mAh. Ultra 2 (2023, A2986/A2987/A2988) uses A2956 at 564mAh. The voltage profiles and PCM specs differ. Despite identical 49mm titanium case dimensions and appearance, the two batteries are not interchangeable. Distributors stocking both generations must carry separate SKUs.
Q2: Does the Ultra 2 battery support the full 60-hour Low Power Mode runtime after replacement?
A: Yes — when the replacement cell delivers rated 564mAh capacity. Apple’s published 60-hour Low Power Mode runtime is based on this capacity at the S9 chip’s efficiency level. A sub-capacity cell (common in commodity aftermarket batteries) will fall proportionally short. Our cells are individually capacity-tested before shipment. Standard use with AOD on is rated at 36 hours; workout tracking with GPS reduces this to approximately 12 hours.
Q3: Does the titanium case make Ultra 2 battery replacement harder than standard Watch models?
A: Yes, in two specific ways. First, the titanium enclosure has tighter machined tolerances than aluminum — an out-of-spec cell will not seat correctly, and forcing it risks damaging the case lip. Second, the 100m water resistance rating (EN 13319) requires more thorough adhesive re-sealing after opening than the standard Watch’s 50m rating. The actual battery installation procedure is similar, but pre-repair verification of cell dimensions and post-repair gasket work are more critical on Ultra 2 than on any other Watch model.
Q4: Will dual-frequency GPS (L1+L5) function correctly after battery replacement?
A: Yes, when the battery delivers stable current under GPS load. L1+L5 dual-frequency GPS draws more current than single-frequency GPS — the Ultra’s battery is specified with a higher peak current rating than standard Watch cells to handle this. A generic or sub-grade replacement cell with high internal resistance will cause voltage sag during active GPS tracking, resulting in signal dropout or reduced fix accuracy. Our A2956 cells are rated to the Ultra’s peak current profile.
Q5: What is the correct disassembly temperature for Ultra 2, and does the Action Button complicate the process?
A: Display adhesive softening: 70–80°C for 60–90 seconds, same as standard Watch models. The Action Button does not directly complicate battery access — it sits on the case side and does not need to be removed for battery replacement. However, the button’s flex cable routes near the battery compartment and must be moved carefully during installation to avoid connector damage. The crown seal also requires re-application of adhesive after reassembly to maintain the 100m water resistance rating.
Q6: Is the Ultra 2 battery a viable SKU for repair distributors given the lower volume compared to standard Watch series?
A: Yes, for the right distributor. Ultra 2 repair volume is lower than S9 in unit count, but the per-repair revenue is significantly higher — Ultra 2 retails at $799–$999, and repair shops charge accordingly. The battery cost is a smaller share of the total job value, which means margin per unit is better. Supplier competition on this SKU is thinner than on standard Watch batteries. Distributors already serving premium Apple repair shops will find A2956 a natural catalog addition with better per-unit economics than high-volume commodity Watch battery SKUs.
