Selecting a Third-Party Battery for Your 13-Inch MacBook Pro 2019-2020
Replacing the integrated battery in Apple's 13-inch MacBook Pro models from 2019 and 2020 requires a precise match to the original A2171 battery design. This specific aftermarket replacement must maintain the slim profile and connector compatibility of Apple's original while delivering reliable power cycles. Buyers should verify their exact MacBook Pro model number (like EMC 3301 or MXK52) against the product's compatibility list before purchase.
Key Considerations Before Buying
- Compatibility is paramount: This battery is designed for specific 13-inch MacBook Pro models with Touch Bar from 2019 and 2020, including the M1 transition year; using it in an incompatible model can cause fitment or charging issues.
- Installation complexity: Replacing an integrated MacBook Pro battery involves careful prying of adhesive strips and handling delicate ribbon cables, which differs significantly from user-replaceable battery designs.
- Performance expectations: Third-party batteries like this one may not match the original Apple battery's exact cycle count or macOS battery health reporting accuracy, which is a common trade-off for cost savings.
What Our Analysts Recommend
Look for listings that explicitly mention inclusion of the necessary pentalobe screwdrivers and spudgers for safe case opening, as this indicates the seller understands the installation process. High-quality replacements will often detail the cell chemistry (typically lithium-polymer) and include fresh adhesive strips for securing the new battery to the chassis, which is critical for preventing rattling.
Batteries Market Context
Market Overview
The market for MacBook Pro replacement batteries is segmented between OEM parts, high-grade third-party equivalents like this A2171 model, and lower-cost alternatives that may compromise on cell quality or protective circuitry. For 2019-2020 models, demand is driven by devices exiting AppleCare coverage and needing affordable out-of-warranty service.
Common Issues
Common problems include batteries that fail to charge to 100%, cause false 'Service Recommended' warnings in macOS, or have slightly different physical dimensions that make installation difficult. Inconsistent performance in sleep mode or rapid capacity degradation after a few months are also frequently reported in this category.
Quality Indicators
Quality indicators include clear documentation of the protection circuit board (PCB) being a new, high-temperature resistant design, not a salvaged unit. Premium listings specify the battery's measured capacity in mAh (typically around 5100mAh for this model) and warranty terms that cover at least 12 months, acknowledging the product's lifecycle.
Review Authenticity Insights
Grade B Interpretation
A Grade B authenticity rating with a 10% estimated fake review rate suggests the majority of feedback is genuine, but shoppers should remain cautious of outlier reviews. This grade is common for specialized replacement parts where experiences vary based on user skill and specific device condition.
Trust Recommendation
Focus on reviews that detail the installation process, initial battery health percentage shown in macOS, and performance after several weeks of use. Be skeptical of reviews that don't mention the specific MacBook Pro model they installed it in or that claim performance identical to a brand-new Apple battery.
Tips for Reading Reviews
Prioritize reviews that mention the included tools, the condition of the adhesive, and any issues with the battery connector. For this product, reviews discussing the M1 model (EMC 3578) experience are particularly valuable, as power management can differ from Intel-based models.
Expert Perspective
With an adjusted rating of 3.5/5, this battery sits in the mid-range of third-party replacements, indicating functional compatibility but potential variability in user experience. The specificity of its model compatibility (covering the A2159, A2289, and A2338 designations) is a strong point, reducing the risk of ordering the wrong part. The rating suggests that when installation is successful, it performs adequately, but outcomes are highly dependent on installer skill and the recipient device's exact condition. The authenticity analysis confirms most reviewers are providing real, nuanced experiences.
Purchase Considerations
Weigh the significant cost savings against Apple's official battery service, considering your technical comfort with the intricate disassembly process. This purchase is most justifiable for users with specific, older MacBook Pro models listed who are comfortable with DIY repairs and accept the possibility of slightly reduced battery health reporting accuracy.
Comparing Alternatives
Shoppers should compare this listing's price, included tools, and warranty against other A2171-compatible batteries, paying close attention to photos of the connector and PCB.
