55 Wh 7.6 V 4-Cell Replacement Battery

This 55 Wh lithium-ion battery is built for Dell laptops that use the R1V85, 451-BBSX, 451-BBSY, 451-BBSU or R97YT part numbers. It supplies 7.6 V from four premium cells and carries CE and RoHS certification. The pack is sold new and includes a one-year replacement warranty against material or workmanship defects.

Suitable for owners of matching Dell notebooks

Buyers who cannot verify the exact part number on their original battery should not purchase this unit, as two different packs exist for the same laptop model and they are not interchangeable. Anyone requiring a different voltage, cell count or capacity must look for another product.

Simple user-replaceable installation

The battery fits into the existing compartment without tools beyond a small screwdriver. The most common issue is ordering the wrong variant because the laptop model accepts two incompatible packs; comparing the original part number and physical layout with the product photos prevents this mistake.
