No batteries included, whats a human double A or triple A?

I'm trying to figure out what my dry weight is in dry cell batteries, a bunch of batteries thats all i was to some women, i saved them having to change the batteries in their rampant rabbit. It's a two way split, i'm as guilty as they were i sure as hell didn't say no. But i've found out i can't have kids, i could have when i was wasting my time being a walking breathing vibrator. It's all too late now. I'm trying to envisage my son or daughters weight in dry cell batteries, 9lbs is average for a baby isn't it whats that in battery weight?
