Replacement Battery for Toshiba Satellite Series

This 6-cell lithium-ion pack replaces original Toshiba batteries across the Satellite A660, A665, C645D, C650, C650D, C655, C655D, L510, L515, M500, M505, M645, P745, P750, P755, P755D, P770, P770D, P775, P775D and U405 lines as well as Satellite Pro C650, C650D, C660 and C660 models. It delivers 10.8V and 4400 mAh capacity for users who need a direct-fit power source without modifying their chassis.

Built-in Smart Chip with Protection Circuits

The integrated control chip manages charging current to reduce heat build-up and extend discharge time between charges. It also provides short-circuit, overheat and overload safeguards that protect both the battery and the laptop during daily use. No extra software or drivers are required; the pack communicates with the notebook’s existing power management.

Black 6-Cell Housing Matches OEM Form Factor

The black enclosure mirrors the original battery’s shape so it locks into the existing bay without adapters or shims. Six lithium-ion cells rated at 48 Wh keep the weight distribution familiar, and the 10.8V output aligns with the laptop’s stock voltage rail. Buyers who need a higher-capacity 9-cell design or a different voltage should look elsewhere.

Questions about this item

How many charge cycles will the 6-cell 10.8V 4400 mAh pack last before it needs replacing?

The battery uses professional-grade lithium-ion cells built to OEM specification and includes a smart control chip that manages charging to extend overall service life.

What limits runtime first when the 4400 mAh battery runs continuously — thermal throttling or capacity?

Runtime is limited by the 4400 mAh / 48 Wh capacity; the built-in protections guard against short circuit, overheat and overload but do not increase the stored energy.

Does the 6-cell 10.8V pack get hot or noisy during all-day use?

The pack has no moving parts so it is silent; the smart control chip and overheat protection keep temperature in check during extended operation.
