Questions about this item
Does this 8-cell 14.4V pack fit a Pavilion dv7-3128ca without any extra hardware?
It replaces the original 464058-121 and 464059-001 batteries used in that model, so the laptop itself is the only thing required.
Will the 4400mAh capacity still charge correctly through the older dv7-1100 charging circuit?
The built-in smart control chip manages charge current and voltage to stay within the original 14.4V specification, so the legacy circuit handles it normally.
How can I confirm the battery is delivering the rated 63Wh after the first few cycles?
Run a full charge, then check the OS battery report or BIOS health screen; it should show design capacity near 63Wh and a cycle count that increments with each full discharge.
