I just bought a thd72a with dual batteries and the emergency alkaline pack it uses "AAA", Can anyone give me an idea on what to feed this, are regular Duracell process ok or do I want to go lithium , I plan on stocking up 100 "AA" and 100 "AAA" You just never know when they will be pushed into service, or when they will sit for months at a time.
