Compatible models

This replacement battery fits Toshiba Satellite models C55D-B5219, C55D-B5310, C55D-B5319 and C55-B5300. It is designed as a direct substitute for the original PA5186U-1BRS pack. The lithium-ion chemistry delivers reliable mobile power for everyday computing tasks. Users with other laptop series will need a different battery.

Capacity and voltage

The pack provides a 2200 mAh capacity at a nominal 14.8 V, matching the electrical requirements of the supported devices. It is also rated to fit 14.4 V systems, giving flexibility across the listed models. Runtime will vary with workload, screen brightness and power settings. Heavy workloads will drain the charge faster than light office use.

Build and certification

The battery uses four premium-quality lithium-ion cells housed in a form factor that matches the original dimensions. It carries CE and RoHS certification, confirming compliance with European safety and environmental standards. A one-year replacement warranty covers defects in materials or workmanship. No tools beyond a standard latch release are required for installation.

Questions about this item

Will the 14.8V 2200mAh 4-cell battery fit my older Satellite C55-B5300 without modification?

The battery is designed for 14.4V or 14.8V systems and lists the C55-B5300 among compatible models, so it installs directly in place of the original pack.

How can I confirm the new PA5186U-1BRS battery is charging correctly after installation?

Insert the pack, connect the AC adapter and verify the charging LED illuminates; the OS battery meter should then show increasing capacity toward 100%.

Does the box include a charger or tools, or must I buy them separately?

Only the 4-cell lithium-ion battery is supplied; the laptop's existing AC adapter and any screwdrivers needed for the battery bay are not included.
