Battery 2-Power A42-G73 14.8v 8 cell 77Wh
The 2-Power A42-G73 is a 14.8 V lithium-ion laptop battery with 8 cells and a rated energy of 77 Wh (5200 mAh). Designed as a direct replacement for models using the A42-G73 specification, this battery provides reliable power for extended mobile use and is compatible with systems that accept the A42-G73 form factor. The unit is finished in black and weighs approximately 0.414 kg.
Manufactured using high-grade lithium cells from reputable suppliers, the 2-Power A42-G73 delivers steady discharge and fast recharge characteristics. Integrated SmartWatch Protect circuitry helps monitor charging and discharging to reduce risk of short circuits and overheating, while the 8-cell design and 77 Wh capacity offer longer unplugged runtime compared with smaller batteries.
Turn off the laptop and disconnect any external power source before replacing the battery. Remove the old battery according to the laptop manufacturer’s instructions, install the 2-Power A42-G73 in the same orientation, and secure it in place. After installation, connect the AC adapter and allow the battery to charge fully before first use to help calibrate the battery management system.
To maximise battery lifespan, avoid exposing the battery to extreme temperatures, store it partially charged if unused for long periods, and use the laptop’s built-in battery calibration and power management settings. If you notice abnormal heat or swelling, stop using the battery and contact the supplier.
