Replacement battery for HP Pavilion series

This 14.8V lithium-ion pack delivers 2600mAh capacity across four cells for 32.56Wh total energy. It replaces HP part numbers including 728460-001, 752237-001 and 776622-001 across Pavilion 14 and 15 models as well as 248, 340 and 350 series notebooks. The unit ships new with FCC, CE and RoHS certification and built-in circuit protection.

Thermals and power draw in daily use

Normal charging and discharge cycles run cool thanks to Grade A cells rated for fast charges and low power consumption. The 20V AC adapter voltage matches original equipment specifications so the laptop's power management sees no difference. No fan or active cooling is required because the battery itself generates minimal heat during typical office workloads.

Behaviour under sustained load

Continuous discharge at full capacity maintains stable voltage until the protection circuit cuts off at the safe lower limit. The four-cell layout spreads current evenly so no single cell overheats during long sessions. Runtime scales with the notebook's actual draw; heavy multi-core tasks will deplete the 32.56Wh reserve faster than light browsing.

Questions about this item

How do I install the LA04 battery in my HP Pavilion 15-f272wm, and which step is often missed?

Power off the laptop, remove the AC adapter, slide the release latch, lift the old pack out, insert the new LA04 until it clicks, then reattach the adapter and power on; the step users skip is fully seating the latch so the pack locks in place

What maintenance will the LA04 need over its life?

The 4-cell lithium-ion pack requires no scheduled servicing; keep the contacts clean, avoid storing it fully discharged, and replace the unit when run-time no longer meets your needs

What limit appears first during sustained use of the LA04?

The 32.56 Wh capacity sets the runtime ceiling; under continuous load the pack will deplete before any thermal or voltage limit is reached
