Important Compatibility Note
The models and part numbers listed above are for reference only.
Some laptops use different batteries even within the same series, so matching by model name alone is not always enough.
To avoid ordering the wrong battery, it is recommended to confirm compatibility with us before purchase.
This ensures you receive the correct hp laptop battery original replacement for your exact laptop.
We also allow return or exchange within 7 days (subject to policy) if the battery does not match, but checking first helps you save time and avoid delays.
