Cameron Sino is a well-respected global manufacturer known for producing batteries for everything from medical equipment to laptops. Their A1322 replacement for the 13-inch Mid 2012 MacBook Pro is favored for its stability and consistent voltage output.
Unlike cheaper knock-offs that might cause the trackpad to bulge or the system to shut down unexpectedly, Cameron Sino batteries use high-grade cells that maintain their health over hundreds of charge cycles. They are an excellent middle-ground option for those seeking professional-grade reliability without the premium price tag of boutique brands.
NinjaBatt has gained significant traction on e-commerce platforms for delivering high-performance batteries at competitive prices. Their "Pro" series for the A1278 (13-inch) and A1286 (15-inch) models features superior Samsung or LG cells, which offer better longevity than standard generic cells.
These batteries often boast integrated smart control chips that communicate effectively with macOS to provide accurate battery health percentages and time-remaining estimates, a feature often lacking in lower-quality replacements.
Xtend batteries are designed with a focus on longevity. For the Mid 2012 user who keeps their laptop plugged in often, Xtend's advanced circuitry helps prevent overcharging and heat buildup, which are the primary killers of lithium-ion batteries.
They offer a solid warranty period and are widely compatible with both the Mid 2012 non-Retina and the Early 2013 iterations that share the same chassis design. Their capacity ratings are strictly verified to ensure you get the runtime promised on the box.
For budget-conscious students or users reviving a secondary machine, Egoway offers a cost-effective solution. While they may not have the brand heritage of NewerTech, Egoway batteries provide a safe and functional replacement for a dead OEM battery.
They are FCC, CE, and RoHS certified, ensuring they meet safety standards regarding materials and electrical emissions. For a 2012 laptop that serves as a backup or media server in 2026, Egoway provides excellent value for money.
Choosing the wrong battery is a common mistake. The Mid 2012 year saw two distinct designs. Use this guide to ensure you buy the correct part:
Model ID: MacBookPro9,2
Battery Model: A1322
Features: User-removable bottom case with standard screws; battery held in by tri-wing screws.
Model ID: MacBookPro9,1
Battery Model: A1382
Features: Similar to the 13-inch, accessible via standard screws.
Model ID: MacBookPro10,1
Battery Model: A1417
Features: The battery is glued into the top case. This requires a much more complex repair process involving adhesive remover.

Absolutely. The 2012 MacBook Pro is highly upgradeable. With a new battery, a solid-state drive (SSD), and 16GB of RAM, it remains a capable machine for web browsing, document editing, and media consumption, far outperforming cheap modern Chromebooks.
After installation, charge the battery to 100% and leave it plugged in for at least 2 hours. Then, unplug and use the laptop until it shuts down automatically due to low battery. Leave it off for at least 5 hours, then charge it back to 100% uninterrupted. This helps the system accurately read the battery's capacity.
This is a classic sign of a swollen battery. In the Unibody MacBook Pros, the battery sits directly underneath the trackpad. If the old battery swells, it pushes up against the trackpad mechanism. Replacing the battery usually fixes this issue immediately.
No. The A1322 is specifically for the thick Unibody 13-inch model. The Retina models use entirely different, thinner batteries that are often glued in. Always check your model identifier (e.g., MacBookPro9,2) before purchasing.
