Replacement battery for Toshiba Satellite models

This 6-cell lithium-ion pack delivers 4400 mAh at 10.8 V for the listed Toshiba Satellite A660, C645D, C650, C655, L510, L515, M500, M505, M645, P745, P750, P755, P770, P775 and U405 series. It suits owners who need a direct replacement for part numbers PA3816U, PA3817U, PA3818U or PA3819U. Buyers whose laptop uses a different voltage or connector will not be able to use this unit.

Thermals and power in normal use

The built-in smart control chip manages charging current to reduce heat during recharge and limits discharge temperature under load. Overheat, short-circuit and overload protections shut the pack down before cells reach unsafe levels. Normal operation stays within the 48 Wh design envelope without requiring extra cooling.

What the bundled items change

No external accessories or software discs are included in the package. The only functional addition is the integrated protection circuitry that enables quicker charging, lower self-discharge and the safety cut-offs described above. Users relying on Toshiba power-management utilities will see no change in software behaviour.

Questions about this item

How do I install the MPL16230P-25 battery in my Toshiba Satellite L750, and what step do people often miss?

Power off the laptop, unplug the AC adapter, slide the release latch, remove the old pack, insert the new 10.8 V 4400 mAh unit until it clicks, then charge fully before first use.

What maintenance or replacement will the 6-cell lithium-ion pack need over time?

No routine upkeep is required; when run-time becomes too short — typically after several hundred charge cycles — replace the battery with another compatible 10.8 V pack.

What limit appears first during sustained use of this 48 Wh battery?

The 4400 mAh capacity determines how long the laptop runs before the pack must be recharged; thermal protection may also activate under heavy load.
