HP 14.8V 2200mAh 4-Cell Li-Ion Battery

This replacement battery fits HP laptops using part numbers 805045-851, 805292-001, HSTNN-DB7A, HSTNN-Q98C, HSTNN-Q96C and P3G13AA. It uses lithium-ion chemistry at 14.8 volts with a 2200 milliampere-hour capacity across four cells. The unit is new and carries CE and RoHS certification for safety and environmental compliance.

Replacing Worn Original HP Batteries

The battery replaces an original HP pack that no longer holds sufficient charge for mobile work. The jump is worth it when the laptop shuts down unexpectedly or runtime drops below useful levels for meetings or travel. It is not for buyers who need a higher-capacity pack than 2200mAh or a different voltage than 14.8V for their specific model.

Sustained Daily Discharge Cycles

Under sustained load the lithium-ion cells deliver steady voltage through typical office, streaming and browsing sessions. The four-cell design maintains consistent output over repeated charge and discharge cycles rather than fading quickly after a short burst. Rigorous testing targets long-term reliability so the pack supports everyday usage across its service life.

Questions about this item

Will this 14.8V 2200mAh 4-cell battery fit my HP laptop that uses part number 805045-851?

Yes, the pack is built to match the 14.8V 2200mAh 4-cell specification and lists 805045-851 among its compatible part numbers.

What is the correct way to install this battery and what step do people often miss?

Power off the laptop, unplug the AC adapter, slide the release latch, swap the old pack for the new one, then charge it to 100% before first use — skipping that full initial charge is the common mistake.

How long before this lithium-ion pack needs replacing?

Expect several years of daily use; when run time falls well below the original 2200mAh rating, a new 4-cell pack restores full capacity.
