Thermals noise and power in daily use
The 10.8 V, 4400 mAh lithium-ion chemistry delivers 48 Wh of energy through an integrated smart control chip that manages charging current and discharge rate. Built-in protection circuits guard against short circuit, overheat and overload conditions during normal operation. No active cooling or fan is present, so the pack runs silently and adds no audible noise to the system. Power draw follows the laptop’s own management profile without extra overhead.
Build quality connectors and daily handling
The black casing houses six cells in a form factor that fits the original battery bay using the stock latch and connector. A one-year manufacturer warranty covers defects in materials and workmanship. Users should verify their original battery model and output voltage before installation to avoid fitment issues. The pack is not suitable for devices requiring a different cell count, voltage or physical shape.

Questions about this item
How do I install the MPL08217P-07 battery in my Compaq Presario CQ60 and what step is often missed?
Slide the pack into the bay until the latch clicks, then charge it fully before first use; many users skip the initial full charge cycle.
What maintenance will this 6-cell 4400 mAh lithium-ion pack need later?
No routine maintenance is required; the pack will eventually lose capacity and should be replaced when run time drops below your needs.
What limit appears first during sustained use of this 10.8 V battery?
The 4400 mAh capacity determines how long the laptop runs before the pack must be recharged.
