OK. Got it. Bottom battery always comes out first. And, I always load the left bay of my charger first, just feels right. So, now I'll put that battery in the back of the 2-cell plastic box (the other in the front) because I always put to top battery in first (which will be the front battery in my box). That works!
No, that's wrong. Wait a minute. The battery in the left bay will go in the front slot because I always put the top battery into my BB first.
I think I've got it. Bottom battery out first. Into left bay of charger. Into front slot in battery box. Into top slot in BB.
That's Bottom Left Front Top, Bacon Lettuce and F**** Tomato!
The ONLY thing to remember is to reverse them at some point. What point? That's up to you.
