This 11.1 V 5200 mAh lithium-ion pack replaces the original PA3635U-1BRM unit in Toshiba Satellite M305-S4848 M305-S4910 and L515-S4010 models. It uses six premium A-grade cells and a built-in protection circuit board to deliver stable power without memory effect. Certified to CE and RoHS standards, the battery is manufactured from eco-friendly materials free of lead and mercury. Each unit is tested before shipment and backed by a one-year warranty.

For owners of the listed Satellite notebooks

The pack fits only 10.8 V or 11.1 V systems that accept the PA3635U-1BRM form factor, so it will not work in laptops requiring a different voltage, connector or cell count. Buyers who need a higher-capacity design, a different physical shape or compatibility with other Toshiba series should look for a model that matches those exact specifications.

Includes battery only

No charger, tools, software or additional accessories are bundled with this replacement cell. The package supplies the battery itself, ready to install after an initial overnight charge and three full charge-discharge cycles to reach maximum capacity.
