Sporty's specs show the Verte as having a 15 hour
battery life, and the ICOM NiMh as 6 hours or so.

I use alkaline cells exclusively for all my aviation equipment: GPS,
Lamps, Transceiver, Active Noise Reduction Headset, ... That way,
it's difficult to find yourself frustrated by an exhausted battery
pack; it's always possible to 'borrow' a cell or two from another
device. And in the event of a forced landing, the redundancy could be
a lifesaver.
