Battery icon, no lightning bolt, not charging

I tried everything I could find in posts on this forum and other Apple communities and struck out on them all. The classic fix is to hold in the power and home buttons. Heard that one among many other variations with the device plugged into outlet power and/or computer with ITunes. No option of that sort worked, but I was determined to get my iPad functioning again and refused to pay Apple support to troubleshoot and fix it. I finally ran across several forum posts that were well written and logical about the lithium battery being discharged to the point that the battery will no longer function properly. I will Not attempt to go into the science behind lithium batteries and why the fix of heating the battery up puts a mild charge back into the battery, etc. If your iPad or other iX device battery has been completely drained and is displaying the red battery icon with a few red strips, and all other troubleshooting measures fail you may want to try heating the device until the back of it is hot to the touch, then try plugging it in and waiting for at least 10-20 minutes.

I had little hope in this fix, but it indeed gave the internal battery in my iPad enough juice to start taking a charge. It is now at 48% and climbing. I am convinced that no other troubleshooting method would have resulted in my iPad battery being jump-started into taking a charge and powering the device on because I tried them all. There are probably a million ways to heat the iPad to attempt this fix with what seems to be the most popular being a hair dryer and standing there for an eternity until the back of the device is hot to the touch. If I told you that I put the iPad on a wooden cutting board and placed in the oven at 170 for 20 minutes I am sure many would not believe it or get holier than thou that I violated some safety commandment of placing the iPad in an oven, but that very well might have worked...
