Battery 2-Power 11.1v 6 cell 57720Wh
The 2-Power 11.1v 6 cell 57720Wh battery is a replacement lithium-ion pack designed to restore or extend laptop runtime. Compatible as a direct substitute for model 45N1042 (MPN 2P-45N1042), this six-cell battery uses high-grade cells to provide consistent energy output and longer unplugged use. With a rated capacity of 5200 mAh and a lightweight design (0.309 kg), it is suited for everyday computing and heavier workloads where dependable power is required.
Manufactured with quality cells from recognised suppliers, this 2-Power battery supports faster charging and stable performance during discharge. Built-in SmartWatch Protect circuitry helps monitor charging and discharging to reduce the risk of short circuits and overheating. The six-cell format balances capacity and weight to deliver extended runtime without significant added bulk.
Turn off the laptop and disconnect the mains adapter before removing the old battery. Follow the laptop manufacturer's instructions to access the battery compartment or service panel, remove retaining screws or clips, and disconnect the old pack. Install the 2-Power battery by connecting the battery connector, securing any screws or clips, and replacing the panel. Charge the battery fully before first use and then operate the laptop as normal.
To prolong battery life, avoid exposing the pack to extreme temperatures, do not short-circuit the terminals, and store at partial charge (around 40–60%) if the battery will not be used for extended periods. Use the laptop manufacturer's or 2-Power recommended charger and follow normal safety precautions while charging.
