I have read where others (Jimbo) reported his detector worked better on lithium batteries.  He was using 8 AA batteries.  Lithium batteries are a little higher voltage than alkaline batteries.

I run a lithium AA 8-pak.  Seems to be enough to carry me for a two week trip (under moderate use).  As a matter of fact, on the last trip I pulled a couple out to put into my GPS who's batt's had succumb (since I wasn't fishing my way out to the exit).  I've used the GPS several times since my trip and the batt's seem to still be going strong.
