ZhanPeng Laptop Replacement Batteries — 81 Models Across Every Major Brand

A failing laptop battery doesn't just cut your runtime — it can throttle CPU and GPU boost clocks, trigger random shutdowns, and leave you tethered to a wall outlet. Our catalog covers 81 replacement batteries for Dell, HP, Lenovo, ASUS, Samsung, Toshiba, Panasonic, and more, each one matched to a specific part number rather than sold as a one-size-fits-all unit. Search by your battery's part number (printed on the original battery label) or your laptop's model name on the bottom chassis to find the exact fit.

Built Around the Part Number, Not Just the Brand

Laptop batteries are defined by their part number, cell configuration, and voltage platform — not just the brand on the lid. That's why our listings lead with the part code: a Dell Latitude 5480 needs a 93FTF (51Wh), while a Latitude 5400 takes a 4GVMP (68Wh), and the two are not interchangeable despite both being Latitudes. Each product page states the exact part numbers and compatible models so you can confirm the match before ordering.

Power Profiles for Four Different Use Cases

  • Business & professional: Replacements for Lenovo ThinkPad (e.g. X200 42T4649), Dell Latitude and Precision (93FTF, 9JRV0, X9FTM), and HP EliteBook — tuned for all-day runtime and stable voltage.
  • Rugged & field equipment: Higher-capacity packs for Panasonic Toughbook CF-30/31/53/54 (CF-VZSU0PW, CF-VZSU71U) and Getac, including 9-cell options for extended shifts away from power.
  • Gaming & performance: Higher-discharge cells for ASUS ROG Strix G15 (B31N1726) and Alienware Area-51m R2 (AA18250, 96Wh), built to hold boost clocks under sustained load.
  • Ultraportable & consumer: Compact packs for Samsung Galaxy Book (AA-PBKN4MR), ASUS VivoBook (B31N1842, B31N2015), and handheld PCs like the Lenovo Legion Go (L23M2PK0) and One-Netbook OnexPlayer.

Cells, Protection, and Testing

Every pack uses new lithium-ion or lithium-polymer cells and an integrated Battery Management System (BMS) that guards against overcharge, over-discharge, overheating, short circuits, and voltage surges. Capacities range from compact 42Wh ultraportable packs to 96Wh gaming and rugged units, with 6-cell and 9-cell configurations where the chassis allows. Batteries are designed to match the reference specifications of the original part — physical size, connector interface, and internal communication protocol — for a plug-and-play fit, and are built to meet international safety standards including CE, FCC, RoHS, and UN38.3 for lithium transport.

Compatibility Tips Before You Order

  • ASUS: Match the B31N/C31N part code, not just the VivoBook/ROG model name — several series share a chassis but use different cells.
  • Dell: Latitude and Precision lines reuse model numbers across generations; always confirm by part number (e.g. 4GVMP vs 93FTF).
  • Higher capacity: A higher-Wh pack (such as 9-cell vs 6-cell) gives longer runtime but may sit slightly raised from the base.
  • Unsure? Email a photo of your old battery label to support@laptopbatteriesadapters.com and we'll confirm the right match.

Frequently Asked Questions

How do I find the correct battery for my specific laptop?

The best way to find the right battery is by using your Battery Part Number. You can find this number on the label of your original battery. For example, look for "J60NH" for Dell or "01AV423" for Lenovo. You can also search by your laptop's specific model name and series found on the bottom of the chassis.

How can I maximize the lifespan of my new laptop battery?

To keep your battery healthy, avoid allowing the charge to drop to 0% on a regular basis. Most modern lithium batteries perform best when kept between 20% and 80%. Also, make sure your laptop has good ventilation. Excessive heat can damage the battery.

Will a replacement battery affect my laptop's performance?

A good replacement battery will enhance your experience. It provides stable power delivery. This helps your CPU and GPU keep their boost clock speeds. They won’t throttle due to a failing battery or low voltage.
