[Tfug] OT: Batteries

How about a missing option:

4) A "proprietary" battery in a commonly available form factor. Lots of 
various cordless phones/radios/etc. use a battery pack (usually AA or C type 
rechargeable cells) permanently bound together in a standard form factor. You 
can pick the batteries packs up at Target/etc. and remove the cover/plug them 
in.

For a large production run you can make/brand your own. If it turns out to be 
a small run, then the option is "go buy X brand cordless phone battery pack 
at Target".
