Questions about this item
How do I install the Dr. Battery MPL08218P-19 in my HP HDX 18 or Pavilion dv7, and what step is often missed?
Power off the laptop, unplug the AC adapter, slide the old pack out, insert the new 8-cell unit until the latch clicks, then charge fully before first use; the step often missed is completing that initial full charge.
What maintenance or replacement will the 4400 mAh 14.4 V pack need later?
No routine maintenance is required; the lithium-ion cells will gradually lose capacity over time and the pack should be replaced when run-time no longer meets your needs.
What limit appears first during sustained use of this 63 Wh battery?
The capacity limit is reached first; after many charge cycles the 4400 mAh rating will decline, reducing the available run-time per charge.
