Buying Guide

Check physical fit and model compatibility

Confirm the battery lists your laptop model or service part number to avoid fitment and connector mismatches

Compare capacity (Wh) not just cell count

Watt‑hours directly indicate usable energy — a higher Wh rating yields longer runtime for travel between charges

Prefer cells and protections over

Look for descriptions mentioning premium cells and built‑in protections (overcharge, short circuit) to improve safety on the road

Factor weight and airline rules

Higher‑capacity batteries weigh more and may be subject to airline watt‑hour limits, so verify Wh complies with carrier policies

Check warranty and return policy

A clear warranty and return window reduces risk if the replacement battery has early failure or compatibility issues
