Dr. Battery MPL16209P-25 6 Cell 10.8V 4400mAh laptop battery

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.
