Compatible HP laptop battery

This 2-Power LA04 battery replaces original HP cells for Pavilion 14, Pavilion 15, 248, 340 and 350 series notebooks. It matches part numbers including 776622-001, 752237-001 and LA04. The 4-cell lithium-ion pack is built to the same physical size as the factory unit. Buyers who need a different voltage or a higher capacity pack cannot use this model.

Thermals noise and power draw

The pack delivers a nominal 14.8V at 2200mAh for 33Wh of stored energy. Lithium-ion chemistry keeps self-discharge low during daily charge cycles. Integrated circuit protection guards against over-charge, over-discharge and short-circuit events. The 225-gram weight adds minimal mass to the original chassis.

Sustained load behaviour

Cells are rated for up to 600 recharge cycles over the service life. Steady discharge maintains voltage stability during long work sessions away from mains power. CE and RoHS certification confirms compliance with European safety and environmental standards. The pack is not suited for users who require hot-swap capability or extended runtime beyond the rated capacity.

Questions about this item

How do I install the LA04 battery in my HP Pavilion 15 and which step is often missed?

Power off the laptop, unplug the AC adapter, slide the release latch, remove the old pack, insert the new 4‑cell unit until it clicks, then lock the latch; many users forget to latch it securely.

What maintenance or replacement will the LA04 need after extended use?

The lithium‑ion pack is rated for up to 600 recharge cycles; after that capacity drops noticeably and a replacement battery will be required.

What limit appears first when the LA04 runs under sustained load?

The 33 Wh capacity delivers limited runtime; under continuous heavy draw the battery depletes quickly and triggers the low‑power shutdown threshold.
