So I haven't charged my laptop in 6 years and the battery is completely dead. If I charge it will turn on but if I disconnect it will turn off. Do I have to replace my battery?

    Yes, you do ... – harrymc Dec 31 '18 at 20:58
  • For six years, I think any battery storage device would be more or less problematic. If you can only use DC power, then I don't think the battery is charging. Replacing the battery is an option. I remember there was also a command under Windows to view the power issue. “powercfg/batteryreport”. This will give a detailed HTML report on battery issues, charge ratings, history of battery use and history of battery charge periods. – daidai Jan 1 at 7:15

You can try using BatteryInfoView by NirSoft to view detailed info about your battery.

Description

BatteryInfoView is a small utility for laptops and netbook computers that displays the current status and information about your battery. The displayed battery information includes the battery name, manufacture name, serial number, manufacture date, power state (charging/discharging), current battery capacity, full charged capacity, voltage, charge/discharge rate, and more...

For your situation, check the Current Capacity (in %) line.

If your battery no longer has sufficient capacity to hold a charge, you will indeed need to replace it.

    Might not work on a 6-year old battery, especially if it's all but dead. – harrymc Dec 31 '18 at 22:12
  • @harrymc As long as the battery is recognized, I don't see why it shouldn't work. I have a 20 year old Win98 laptop that recognizes the battery as being plugged in, even though it holds zero charge. – wysiwyg Dec 31 '18 at 23:08
