Back in Battery 

Originally an artillery term for a gun which has completed its recoil/postfiring cycle and is ready to fire again. Common usage now is 'ready to go,' or recovered. Also seen as 'Back to Battery.'

"I set my hair on fire last night, but five hours' rack time and I'm back in battery."
