I’ve opened my laptop

Lithium polymer battery
model:3282122-2S
Nominal voltage: 7.6 V
Charge limit voltage: 8.7 V
Rated capacity: 4500mAh 32.4 Wh
Manufacturer: Dongguan Nuowei Energy Co., Ltd

Based on my electronics background theoretically, we can use a charger that can provide 9Volts output and 2000mA. For sure internally there are some voltage converters that convert 12V to lower DC like 7,2 or 7.6 (nominal voltage). This means the laptop will charge around in 2h20m from 0 to 100%.

My Ezbook 3 V4 can work on battery for 4h only  like many users. One reason why I selected this laptop was the battery…TOTAL FIASCO!

Using batteryBar, my discharge rate is always 3800mW, doesn’t change (strange).

If my laptop consumes 3800mWh and if battery capacity is 48000mWh. In ideal environment 48000/3800=12,63 hours!

Any idea what the users can do?
