Direct replacement for IdeaPad S-series netbooks

This 11.1 V lithium pack delivers 2600 mAh capacity and matches the original dimensions of 202.5 x 24.96 x 28.14 mm.

Upgrade from a depleted or swollen original cell

When the factory battery no longer holds a charge or shows physical swelling, this certified unit restores full runtime without modifying the chassis. The jump is worth it if the laptop otherwise meets your needs and the original part numbers 42T4682, 45K1275 or 51J0399 match your service tag. ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm safety compliance.

Drops into the existing battery bay

The pack weighs 334.0 g and uses the same connector layout as the OEM design, so no adapters or cables are required. It frees you from relying on AC power for portable use and eliminates the fire risk of a failing cell. Buyers who need a higher-capacity format or a different voltage should look elsewhere.
