Buying Guide

Match voltage and connector

Confirm the replacement battery lists the exact nominal voltage and connector type for your vacuum model to avoid incompatibility or damage

Check capacity (mAh) for runtime

Higher milliamp-hour (mAh) ratings generally deliver longer run time; compare the listed mAh (for example 6200–7000mAh or manufacturer spec) to your original battery

Verify model compatibility

Look for explicit compatibility with your vacuum series (examples include Dyson V7/V11/V15, Roborock S5–S7, Wyze/Xiaomi robot lines, Shark AI) to ensure physical fit and software acceptance

Prefer known chemistry and cell quality

Choose lithium-ion replacements with clear specs and reputable cell sourcing to reduce risk of premature failure or swelling

Compare user ratings and reviews

Use aggregated user scores and feedback about fit, runtime, and longevity to assess real-world performance beyond raw specs
