Replacement battery for Toshiba Satellite

The Dr. Battery MPL16209P-T01 is a new six-cell lithium-ion pack rated at 10.8 V and 4400 mAh. It replaces the original PA3634U-1BAS and PABAS228 modules across a wide range of Satellite and Satellite Pro models including the A660, A665, C650, C655, P755 and P775 families. Owners of those laptops can restore factory runtime without adapters or modifications.

Built-in protection chip changes daily use

A smart control circuit manages charging current, reduces idle draw and extends discharge time compared with unprotected cells. The same circuitry provides short-circuit, overheat and overload safeguards so the pack shuts down safely if a fault occurs. Buyers who need hot-swap capability or external charge indicators will not find those features here.

Six-cell 48 Wh capacity sets the practical limit

The 48 Wh energy rating defines maximum runtime per charge and cannot be increased by firmware or settings. Systems that originally shipped with higher-capacity nine-cell packs will see shorter battery life with this unit. Users who require all-day operation away from mains power should verify the original specification before ordering.

Questions about this item

How many cells will eventually need replacing in this 6 Cell Lithium-Ion pack?

The pack contains six lithium-ion cells; when run-time drops below your needs the whole 6 Cell unit is swapped as one item.

What is the first limit reached during continuous discharge at the rated 4400 mAh capacity?

The 48 Wh energy rating sets the total run-time ceiling; once that charge is spent the voltage falls below the 10.8 V nominal level.

Does the built-in smart control chip add noticeable heat or fan noise during all-day operation?

The chip manages charging and protection internally; the battery itself has no moving parts and produces no audible noise.
