Laptop Batteries – Reliable Replacement Packs for Everyday Use
Find quality replacement batteries for laptops across major brands (Dell, HP, Lenovo, Asus, Acer, MSI and more). Each product page lists the exact part numbers (P/N), voltage group, capacity (Wh), and compatible laptop models to help you buy with confidence.

Why choose our batteries

Clear specifications: labeled capacity (Wh), voltage (V), cell configuration and connector for a precise fit.
Compatibility-first content: product pages include OEM P/N cross-references (e.g., HT03XL, LK03XL, WDX0R, 6GTPY) and model lists.
Quality focus: batches tested for charging behavior and protection (over-charge/over-discharge/over-current/temperature).
Support: quick pre-sales compatibility checks and after-sales guidance for installation and calibration.

How to choose the right laptop battery

Match by Part Number (P/N): open your laptop (if possible) and note the code on the old pack (e.g., HT03XL, WDX0R). Search the same P/N on this category or use our model filters.
Confirm voltage group: keep within the same family (e.g., 11.1/11.4 V vs 14.4/15.2 V). Do not mix voltage families.
Pick capacity (Wh): higher Wh = longer runtime. Some laptops offer standard and high-capacity options; check if a larger pack requires removing a 2.5″ HDD bay or different base cover.
Check connector & fit: verify the plug orientation, cable route, and screw posts match the original.
Review the compatibility list: make sure your full model string (series + suffix) appears or is covered by the family list.

Quick compatibility checklist

Exact P/N on your old battery (or service manual) matches the listing.
Voltage group is identical (11.1/11.4 V family or 14.4/15.2 V family).
Capacity (Wh) meets your runtime goal; physical fit confirmed for higher-Wh options.
Connector type/position and mounting holes align with your chassis.

Installation & first-use tips

Power off, unplug AC, and work on a non-conductive surface; avoid metal tools on contacts.
Seat the battery connector straight; do not pull on wires. Re-use all mounting screws.
First charge: 100% and rest 30–60 min → use to ~10–20% → charge to 100% (one calibration cycle helps the gauge learn the new pack).
Windows users: generate a Battery Report to verify capacity:
powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"

Business & bulk orders
IT teams, schools and resellers can request tiered pricing for 10/20/50+ units, with batch consistency and documentation (UN38.3 summary/MSDS) on request. Tell us your target P/Ns, models, quantities and required delivery window.

FAQ

Are aftermarket laptop batteries as good as the originals?
Reputable replacements match OEM capacity and protections. The key is correct voltage family, connector fit, and honest Wh labeling.

How long will a new battery last?
Typical runtime depends on your laptop’s power draw; lifespan is commonly ~2–4 years (≈ 300–500 cycles) with sensible temperatures and charging habits.

Will I lose data when I change the battery?
No. Your files and OS live on the SSD/HDD, not the battery. Always shut down first to avoid losing unsaved work.

What if my old battery is swollen?
Power down and replace immediately. Do not puncture or compress a swollen pack; recycle via e-waste channels.
