Battery 2-Power 11.1v 6 cell 57Wh Laptop Battery replaces B-5090
The 2-Power 11.1V 6-cell 57Wh laptop battery is a replacement unit for models using the B-5090 type. Built with high-grade lithium-ion/polymer cells, this battery offers a capacity of 57Wh (5200 mAh) and a compact weight of 0.317 kg to restore portable power and extend laptop runtime between charges.
Manufactured from quality cells sourced from established producers, the 2-Power battery supports reliable charging and consistent discharge performance. The SmartWatch Protect circuitry monitors charging and discharging to help prevent short circuits and overheating, providing a safer power solution compared with unprotected alternatives.
Turn off the laptop and unplug it from the mains. Remove the existing battery following the laptop manufacturer's service instructions and install the 2-Power replacement, ensuring correct alignment of contacts and secure seating. After installation, charge the battery fully before first use. Observe the laptop's battery status indicators to confirm proper operation.
Charge and discharge the battery according to the laptop manufacturer's guidelines, avoid exposure to extreme temperatures, and store the battery partially charged (around 40–60%) for long-term storage to preserve lifespan.
