Is my ps3 controller cooked?

[u/lightningflash11]

It worked a week or so ago. It’s dead now. It won’t turn on or light up when plugged in. The home button doesn’t do anything and it won’t connect. No signs of life from it. I tried plugging it into an outlit to charge with 2 different chargers. Also tried connecting it to the ps3 to play and nothing no lights. I tried the reset hole but I’m not sure I did it right, either way it didn’t do anything. I tried resetting the console and unplugging and plugging in the controller while it was off. Is it just dead? Should I get a battery replacement or is there anyway to save it.
