SE battery swap! charging Qs

[mshkttck]

I am about to swap an se battery into a normal ZZ. I will also make a stand alone charger using an extra controller. Would the swapped se battery be able work with the charger's 2 AAAs directly? Should I remove a AAA? Is there anything else I should do or know before I try this? I recently put another zz out of its misery attempting this, and I really dont want to ruin a new one.

thanks for your time
