TREE.NB LA04 8-Cell 5200mAh Replacement Battery for HP

TREE.NB LA04 is an 8-cell high-capacity replacement battery engineered to restore and extend runtime for compatible HP Pavilion 14/15 and G1 series laptops.

This direct-from-manufacturer battery swaps into many Pavilion and G1 notebooks as a practical, lower-cost alternative to OEM packs. It uses eight Li-ion cells to deliver 5200mAh at 14.8V (compatible with 14.4V systems), and its slightly lower mounting profile lifts the laptop off the work surface, improving passive airflow. The pack is designed with overcharge/discharge protection, tested to meet CE, FCC and RoHS guidelines, and includes a 24-month warranty with responsive support.

How much longer will this battery run compared with the original?

With eight cells and a rated capacity of 5200mAh, this replacement provides extended runtime compared with many stock packs that use fewer cells. Real-world battery life varies by workload, screen brightness and system configuration, but heavier capacity generally translates to noticeably longer use between charges.

• 5200mAh nominal capacity for prolonged sessions
• 8-cell configuration increases usable run time versus 4–6 cell originals
• Lower mounting height improves cooling, which can indirectly extend effective runtime

The cell pack is manufactured with multiple safety features and quality checks. It includes protective circuitry to guard against overcharge and over-discharge, and undergoes factory testing to comply with common international safety standards.

• Li-ion chemistry with low power-consumption IC design
