Replacement battery for Tecra Z40-A series

This lithium-ion battery replaces the original PA5149U-1BRS unit in Toshiba Tecra Z40-A models. It supplies 3.8 Ah of capacity in a black housing. The part is built for owners of compatible Z40-A notebooks who need a new power source.

Simple swap with correct alignment

Installation requires removing the bottom cover and disconnecting the old pack before fitting the replacement. The connector keying prevents reverse insertion. Problems usually arise when the battery latch is not fully engaged or when the BIOS is not reset after the swap.

3.8 Ah capacity matches original spec

The 3.8 Ah rating determines whether this unit matches the runtime of the factory battery. Buyers who need a higher capacity for longer unplugged use will not find it here.

Questions about this item

How can I confirm the DS-CS-TOZ400NB is working after installing it in my Tecra Z40-A-10K?

Power on the laptop and verify the battery icon shows charging; the operating system should report a 3.8 Ah capacity and hold charge through normal use.

What comes in the box with the DS-CS-TOZ400NB and what must I buy separately?

The package contains the replacement Li-ion battery only; no tools, screws or AC adapter are included, so have a suitable screwdriver ready for the swap.
