So, I have this Acer ES1-523, and the battery doesn't work. I don't know if it's totally broken or if it simply got over discharged and can't be charged with the laptop IC anymore. The laptop is 3 years old and it has been used just like a regular laptop, nothing crazy, it doesn't get hot at all because components are very weak, it has a 45W charger, that tells you everything (laptops normally have at least 100W chargers). The laptop works just fine as long as it's plugged in to AC, but whenever you remove the AC, instant shut down, as if there where no battery at all. Nevertheless, Microsoft wrongly reports the battery is fully charged, and it detects it, doesn't report any problem. The battery appears to be model 2ICP4/80/104 from Acer I believe,
I disassembled the laptop and took off the battery, and I'm gonna post some pictures and also measurements, wondering if you can help me charge it manually:
Measurements, respecting the sign (polarity):
From orange to red: +1.656V
From orange to yellow: +2.533V
From orange to green or blue: +2.432V
From orange to black: +2.535V
From red to black: +25.0mV
According to my understanding of physics, if from orange to red there is 1.656V, and from orange to black there is 2.535V, from red to black there should be -1.656+2.535= 0.879V. That's my first question.
I don't have a lab power supply, I only have the laptop charger (19V, 2.375A) and AA, AAA batteries. Is there a way I can revive this battery? Like manually charging it somehow?
I know these batteries should start with 0V charging, go up the the nominal value almost immediately, charge at constant Amperage during the first phase while the voltage increases slowly, then about 50% you keep the voltage constant and the amperage drops slowly (second phase).
