Dr. Battery MPL08255P-01 6-cell 4400 mAh 10.8V laptop battery

Replacement for HP 3125 and EliteBook series

This 6-cell lithium-ion battery delivers 4400 mAh at 10.8V for HP 3125 Notebook, EliteBook 6930p, 8440p and 8440w Mobile models. It also fits Compaq 6530b, 6535b, 6730b and 6735b units plus HP 6500b, 6700b and Pavilion dm1 series laptops. The pack suits owners who need a direct swap for an ageing original.

Upgrades worn 6-cell packs rated at 48Wh

The unit replaces OEM part numbers including 646656-421, 646657-241, 646657-251, 646657-421, 646755-001, 646757-001 and A2Q96AA. It restores runtime when the original cell group no longer holds charge through a typical work session. Buyers whose machines require a 9-cell or higher-capacity block will not find that option here.

Simple bay swap with built-in protection

The battery seats in the standard compartment without tools; the smart control chip manages charging current and provides short-circuit, overheat and overload safeguards. Common issues arise when the original part number or voltage label is not verified against the compatibility list, leading to a physical or electrical mismatch.
