Electrical Specifications
The pack uses six lithium-ion cells rated at 10.8V and 4400 mAh, delivering 48 Wh of energy. A built-in smart control chip manages charging to reduce power consumption and extend discharge time. Integrated protections guard against short circuit, overheating and overload conditions during normal operation. The battery is supplied new and carries a one-year manufacturer warranty from Dr. Battery, established in 2006.
Sustained Use Behaviour
Under continuous load the smart chip regulates output to maintain stable voltage while the protection circuits prevent thermal runaway. The 48 Wh capacity supports extended mobile sessions away from mains power. Users needing longer runtime per charge or a higher cell count should consider alternative batteries with greater capacity.

Questions about this item
How do I install the MPL03238P-19 battery in my Asus X75VD?
Power off the laptop, unplug the AC adapter, slide the release latch on the bottom case, remove the old pack, insert the new 6-cell unit until it clicks, then reconnect power and charge fully before first use.
What maintenance will the 4400 mAh lithium-ion pack need over time?
No routine maintenance is required; keep the contacts clean, avoid leaving the battery at full charge during long storage, and recharge it every few months if the laptop is unused.
What limit appears first during sustained heavy load on this 10.8 V pack?
Voltage sag under high current draw reduces run-time before the over-current protection activates, so continuous gaming or rendering sessions will drain the 48 Wh capacity faster than light use.
