What should i do in this situation?

My big brother is being a jerk because I ”lost” his battery for his psp.So i wanted to use it this one day and he was ok with it.Then when I didn’t need it anymore,it told him i put it in this box.Then he said ok.Now though the battery is not inside the box and now he is p*ssed off.However,we have about 3 more psp batteries inside our house.Now he said i have to find his battery or buy him a new one.Then i said no.Then he had pushed me down.I dont know what to do now because i can’t beat him up and i don’t want to snitch on him because i am not a person who snitches.In fact, i hate snitches.So what should i do now?
