2-Power pääakku 11,55V 4380mAh 50,5Wh (2P-996QA254H)

When your laptop's runtime drops to minutes, the 2-Power Main Battery Pack restores full mobility with a 50.5Wh Li-ion cell that matches or exceeds the original specification. Unlike generic replacements that degrade within months, this pack uses grade-A cells and a 3-cell configuration for stable output across hundreds of charge cycles. The 11.55V nominal voltage aligns with modern ultrabook platforms, while 4380mAh capacity delivers enough energy for a full workday away from the wall. Built-in protection against overcharge, over-discharge, short circuit, over-current and over-temperature keeps both the battery and your laptop safe. Installation is tool-free on most compatible models, and the black housing blends seamlessly with the device.

Highlights

• 50.5Wh energy storage for extended unplugged use
• 4380mAh capacity with 11.55V nominal output
• 3-cell lithium-ion construction with grade-A cells
• Five-layer safety: overcharge, over-discharge, short circuit, over-current, over-temperature
• Rechargeable design rated for hundreds of cycles
• Black internal form factor fits original battery bay

In daily use

Slide the 2-Power pack into the battery bay and power on—no driver installation or configuration needed. The battery communicates with the laptop's fuel gauge, so remaining charge is displayed accurately in the OS. During heavy workloads, the stable voltage curve prevents sudden shutdowns even below 20% capacity. For professionals who move between meetings, classrooms or job sites, the extra runtime removes the need to carry an AC adapter. The pack recharges using the laptop's standard charger, reaching 80% in roughly two hours on most systems. Over time, the cell balancing circuitry maintains uniform voltage across all three cells, delaying the capacity fade that plagues cheaper alternatives.

Final note

Before ordering, verify that your laptop model is listed in the manufacturer's compatibility documentation. The 2P-996QA254H is engineered as a direct replacement, but physical connector and voltage must match exactly. When in doubt, compare with the original battery part number printed on the existing pack.
