Sam's Club has the exact same Energizer Ultimate Lithium batteries in an 18
pack for $19.95.
This is the best deal I have been able to find.
They work great in the KX3.

Non-rechargeable AA batteries aren’t that expensive. $12 for an 8-pack. With
3000 mAh, they should last a long time on receive, up to 20 hours.

If cost is not but weight is an issue, lithium AA work well. I expect that
you get at least 10 hrs receive. They do not leak.
I used KX3 to locate noise with small loops, with limited success due to
poor dieirectivity. If your noise sources are on 80m, the new RDF from
RigExpert works very well.
What you're describing is the discharge curve for any alkaline chemistry
battery. Their voltage begins to decay immediately upon use. NiMH batteries
have a much flatter curve over the life of a charge cycle.
I recommend these or Eneloops.

First, and most important, don't leave alkaline cells in your radio for long
periods. They will eventually leak. If you have the KXBC3 installed, I
suggest high quality Low Self Disc
Note that "low self-discharge" or "precharged" batteries are a must.
You can get higher capacity batteries, but they'll always be dead when
you reach for the rig.

Another caution to not leave alkalines installed. I used to swear by
Duracell, but they changed around the time Gillette bought them. In spite
of the "10 year no leak" marketing, I've stopped buying alkalines entirely
due to newer Duracells destroying a thousand dollars worth of gear. Makes

Although a bit expensive, AA size Non-rechargable lithium batteries will
give longer life.
Rechargeable Ni-MH batteries will also last a longer time. If you do
not have the internal charger, you will have to remove them for
charging, so carry a 2nd set of fully charged batteries.
I have just put my KX-3 into portable service trying to locate noise sources
around my property and neighborhood. I put eight brand new Duracell alkaline
cells into the KX-3 and turned off the backlight. Preamp is set to 20 db gain
and I am using headphones with a homemade 26 inch loop for DF.
