So I just bought a Nitecore Intellicharger i4. It's been many years since I have used rechargeables so I'm a bit confused 
The manual says if I'm only charging 2 batteries then I should use slots 1 & 3 or 2 & 4 so effectively leaving an empty slot in between.
If I wanted to charge 2 x AA's and 2 x AAA's for example does it matter what order I insert them in or does this only apply when charging 2 batteries??
Also what do peeps use to store their batteries when not being used?
Thanks!!
