Buying Guide

Confirm model compatibility

Match the battery to your exact iPhone model (e.g., iPhone 12 Pro Max, 13 Pro, 13 Pro Max) to ensure connector and dimension compatibility

Compare battery capacity

Higher mAh (for example, 12,000–18,800 mAh in our set) indicates greater charge potential but check physical fit and manufacturer guidance

Look for included repair tools

Batteries that come with a repair tool kit simplify DIY replacement and reduce the need to buy separate screwdrivers and pry tools

Check brand reputation and reviews

Prioritize vendors with consistent star ratings and substantial review volume to gauge real-world reliability and return experiences

Assess warranty and safety features

Choose batteries from sellers that mention safety protections and a clear warranty or return policy to mitigate risks with lithium-ion replacements
