  • 5200 mAh capacity powers longer sessions between charges

Compatible Laptop Models

This replacement battery fits Toshiba Satellite T135-S1309, T135-S1310, M305-S4822 and T135D-S1324 laptops. It is built for owners of those specific models who need a new power source. Buyers with different Satellite series or other brands cannot use this unit.

Installation Notes

The battery uses a standard six-cell lithium-ion pack that slots into the laptop's existing bay. No tools or soldering are required for the swap. The only common issue is forgetting to charge the new pack overnight and run three full cycles before expecting maximum capacity.

Voltage And Capacity Limits

The pack operates at either 10.8 V or 11.1 V and delivers 5200 mAh from its premium cells. It will not work with laptops that require a different voltage range. Runtime scales with the host system's power draw, so heavy workloads reduce usable time.

Questions about this item

How can I verify the 5200mAh capacity is performing correctly after installing the battery?

Charge the new battery overnight, then complete three full charge and discharge cycles; the operating system should then report a design capacity close to 5200mAh.

What comes with the battery and is any extra hardware needed for installation?

The package contains the 6-cell lithium-ion battery only; no additional cables, adapters or tools are required for fitting it into the compatible Satellite models.

My laptop is a T135-S1310 — should I choose the 10.8V or 11.1V version?

This single replacement fits both 10.8V and 11.1V systems, so no separate version selection is necessary for the T135-S1310.
