Replacement battery for Toshiba Satellite

The Dr. Battery MPL16232P-25 is a 6 cell lithium-ion unit rated at 10.8V and 4400 mAh. It replaces original Toshiba part numbers PA5027U-1BRS, PA5121U-1BRS and the PABAS259 to PABAS263 series. Compatible models include Satellite A660, A665, C645D, C650, C650D, C655, C655D, L510, L515, M500, M505, M645, P745, P750, P755, P755D, P770, P770D, P775, P775D and U405. Buyers who need a different voltage or a higher capacity pack cannot use this unit.

Thermals noise and power draw

The battery uses professional grade cells built to OEM specification and includes a smart control chip that manages charging and discharge. Protections for short circuit, overheat and overload are integrated to maintain safe operation. Lower power consumption during use supports longer run time per charge. No active cooling or fan noise is involved because the pack is a passive component.

Bundled accessories and software impact

The package contains the battery only; no tools, cables or installation media are supplied. A one year warranty from the manufacturer covers defects in materials and workmanship. The supplier provides online guides and a YouTube channel for installation reference, but no proprietary software is included. Users who require a complete service kit or diagnostic software must obtain those separately.

Questions about this item

How do I install the Dr. Battery MPL16232P-25 in my Toshiba Satellite P855?

Power off the laptop, unplug the AC adapter, slide the release latch to remove the old pack, align the new battery with the bay, press firmly until it clicks, then recharge fully before first use.

What maintenance or replacement will this 6-cell 4400mAh battery need later?

The lithium-ion pack is sealed and maintenance-free; runtime will gradually decline over hundreds of charge cycles, so replace it when operating time no longer meets your needs.

What limit appears first during sustained use of this 10.8V 48Wh pack?

Thermal protection and the smart control chip will throttle or cut output if the pack overheats or draws excessive current, preventing damage during heavy loads.
