2-POWER pääakku korvaa HSTNN-1B8C - akku - 4 113 mAh

When your HP laptop starts losing its charge faster than you can find an outlet, this 2-POWER Main Battery Pack steps in as a direct replacement for the original HSTNN-1B8C. It delivers the same 10.8 V output and 44.42 Wh energy as the factory unit, but with fresh Li-ion cells that hold a full charge cycle after cycle. No software tricks, no compatibility guesswork—just a straightforward swap that brings back all-day runtime.

Highlights

• Replaces HP part number HSTNN-1B8C exactly, with identical voltage and connector layout.
• 4113 mAh capacity and 44.42 Wh energy give you the same runtime as a new original battery.
• 6-cell Li-ion construction balances weight and endurance for everyday carry.
• Built-in protection against overcharge, over-discharge, over-current, and short circuits.
• CE and RoHS certified, so it meets strict safety and environmental standards.

In daily use

Slide this battery into the same bay as your old one and you are back to working untethered. The black housing matches most HP notebooks, and because it uses the same charge controller logic, your laptop's battery gauge reads it correctly from the first boot. You can leave it plugged in overnight without worry—the overcharge protection cuts off current when full. And if you accidentally run it down to zero, the over-discharge guard prevents cell damage that plagues cheaper third-party packs.
