Replacement battery for Satellite M30 and M35

This Axiom lithium-ion pack replaces the original PA3331U-1BAS and PA3331U-1BRS cells in Toshiba Satellite M30 and M35 notebooks. It is built to OEM specifications using lithium-ion chemistry and carries RoHS environmental certification. The pack weighs approximately 14.50 oz and is supplied new.

Direct swap with proprietary form factor

The battery uses a proprietary size that matches the factory compartment exactly, so installation is a simple slide-and-lock action with no tools required. Because the shape is model-specific, it will not fit other Satellite series or non-Toshiba notebooks. Verify the part number on your old pack before ordering to avoid a mismatch.

Restores mobile runtime for supported models

The cell delivers 100% OEM-compatible capacity for the M30 and M35 platforms, letting you work unplugged for the same duration as the original battery. It does not add extra capacity beyond the factory specification and cannot be used in laptops outside the listed compatibility list. Rechargeable lithium-ion chemistry supports repeated charge cycles.
