Replacement for HP Envy series

The GreenTech N55629-005 SA04XL is a new four-cell lithium-ion battery built to fit a wide range of HP Envy 15, 17 and x360 models. It replaces OEM part numbers including HSTNN-UB7U, L43267-005 and L43248-542, giving owners of compatible laptops a direct swap for a depleted original pack.

Thermals and power behaviour

The 15.4 V, 55.67 Whr pack delivers stable current with low self-discharge and built-in circuit protection, so the laptop runs at its normal temperature and fan profile without extra heat or noise. CE, FCC and RoHS certifications confirm the cells meet safety standards for everyday use.

Build and daily handling

The black casing measures 10.7" by 3.95" by 0.25" and weighs 0.7 lb, matching the slim internal bay of the supported Envy chassis. No extra cables or adapters are required; the battery seats with the original screws and connectors, letting you close the lid and carry the device exactly as before.

Questions about this item

How do I install the SA04XL battery in my HP Envy 17-CG, and what step is often missed?

Power off the laptop and disconnect the AC adapter. Remove the bottom case screws, lift the cover, and disconnect the old battery cable. Connect the new 15.4 V pack, secure it, and reassemble. The step often missed is disconnecting the battery cable before removing the old pack.

What maintenance or replacement will the N55629-005 need later?

The 4-cell lithium-ion pack will gradually lose capacity over charge cycles. No user-serviceable parts exist inside. When runtime becomes too short for your workflow, replace the entire unit with another SA04XL or compatible HSTNN-UB7U part.

What limit appears first during sustained use of this 55.67 Whr battery?

The 3470 mAh capacity sets the total energy available per charge. Under continuous load the pack will reach its depth-of-discharge limit and require recharging before the voltage drops below the laptop's safe operating threshold.
