It all depends on chemistry.

The "rules" we had for NiCd and NiMH don't apply anymore. 
Generalizations about batteries will get people in trouble with Li chem 
batteries. If not a fire then possibly a ruined battery pack or worse, 
radio.

As an anecdote. I witnessed a HAZMAT training session 15 years ago that 
the local fire department put on. It involved an early Li battery, about 
the size of a quarter, and a fire in a galvanized steel bucket. When the 
Li cell reached the proper temperature, BOOM! The steel bucket ended up 
looking like a Mum.

Li chem batteries are much safer now but I still wouldn't put any IN an 
expensive radio.
