In the following image, note the positive top metal is only separated from the negative body by 1mm or less, so it is very easy to short a Ni-MH AA batteries and even a kid just inserting the positive side to the spring in battery compartment can cause the short which can burn the battery.

I threw all the 25 pcs of NiMH AA. What kind of 12V batteries where the positive and negative are so far apart there are no possibilities of accidental short when inserted to spring edges in negative polarity of say toy battery compartments? As well as fulfilling my high ampere requirement (due to 4 channel amplifier in one unit instead of just single channel).

Not clear if you're asking a question or not.
The only 12V batteries that I know of are very small batteries used in things like some ceiling fan remotes. And those are far shorter than a double A battery. Off hand I don't know the chemistry either.
