Hi there.
I have an old laptop with crappy battery life (mainly because of the age of the machine and the tech of the time). From the command prompt in Windows 10 I used powercfg /batteryreport to generate a report of the battery.
It states the battery is a 62160 mWh (62 Wh) 6-cell battery with full charge capacity of 50816 mWh (51) Wh. How accurate is this information? I don't think the battery life is very good, but when I went online to look for new batteries, I see that most of the inexpensive replacement parts are 4400 mAh to 5200 mAh, which corresponds to 49 Wh to 58 Wh. However ,those are all non-OEM parts so who knows how accurate those numbers are and how good the quality of the cells is. So, if the battery report is accurate, I won't buy one of those batteries because it seems pointless, as my current battery is still almost 90% of one of those higher capacity batteries, and actually higher capacity than the low end models. Also, the OEM batteries essentially don't exist anymore, but even if they did, this battery is still over 80% of the original capacity, if the Windows 10 battery report is accurate.
I can get a 7800 mAh (87 Wh) 9-cell battery that fits, but not surprisingly it costs twice as much, and again who knows how accurate that info is. I'd rather just put that money toward a new Core M laptop or something.
