Phone Won't Charge/Turn On

[Cr8zyC8tL8dy]

In July I upgraded to the Samsung Galaxy S4. I tried selling my mint condition Galaxy S2 Epic 4G Touch on eBay, but had no takers. It had a brand new battery in it which had bee used for a total of about 3 months. Now, come (almost) December, my mom said, I want your old phone since you didn't sell it. I said, okay, why not. I she can't figure out how to use it, I can always try and sell it again, right? So, I decided to put it on the charger and get it ready so we could switch it over to her account. The problem is, as soon as a plugged it in, the little blue light flashed to tell me it recognized that I plugged it in, and then nothing. The little battery icon didn't show up, the screen stayed black. I tried holding the power button in and nothing happened. I did some Google searched and found nothing. The phone has been laying here on a dead battery for 4 months, but that battery was only 3 months old at the time. I have no idea if that has anything to do with it or not? Can anyone help me? She could have got a brand new one for free via Sprint for her upgrade, but they are sold out. She doesn't want to spend $99 on an S3 if I can get this one working, makes sense. Any ideas/advice is appreciated, thank you!

Got any different charging cables? Or, the original battery, just to test?

I tried the USB charging cable that came with the phone, which also works just fine with my Galaxy S4 and I tried the charger (wall) that came with Galaxy S4. Nothing works. The original battery was DOA (actually bulging in the center), which is why I replaced it back in the spring in the first place, it's long been disposed of. I'm still hunting down the original wall charger for the Galaxy S2, but the S2 and S4 chargers are exactly the same.
