IDK what i left on to kill my battery today but anyway, i jumped the car and it started right up, ran fine and then i went home and went to leave again and no start, no cranking even. When i hook up the charger it will start with the charger on it but if the charger aint runnin it wont even start to crank over. Is my battery just completely dead?

 

Sounds like it

 

Try and take it to autozone/kragens type and ask them to test your battery and if it needs a recharge.

 

yeah. depending on how old your battery is, sometimes it will recharge its self when you jump it. but if the battery is old, it wont recharge. sounds like its time to buy a new one
