Has anyone else noticed that their Etrac seems to perform better with a partially discharged battery? The last few times out with my Etrac with a fully charged battery, I seemed to start identifying the good targets from the junk much better after a couple of hours into the hunt. Today I started with a battery with about 75% charge and I started nailing the good stuff right off the bat.

Etrac performance related to battery charge level?

It has nothing to do with it.
I really didn't think that the battery run time would make much difference with today's detectors, but I know for a fact that battery charge levels did make a difference in my 1980 White's coinmaster. I kept noticing that I would get in a "groove" and nailed the deeper silver with much more frequency than other times while hunting at the same site using the same settings. After observing this several times at the same site, I noticed that when I hit the "groove", my batteries were about half discharged. On one particular hunt, I was getting ready to pack up after hunting this site hard for 4 hours. As I was loading my stuff up, a local walked over and asked about my detector and I proceeded to demonstrate how the detector worked. After completing two or three sweeps I got a solid signal in an area that I thoroughly covered a few hours earlier and dug a 1853 O half-dime at about 6 inches. I am just getting back into detecting after 25 years and the technology has changed a lot.

Yes, the detector technology has advanced by leaps and bounds since the 1980s! I think the lesson to be learned from your last 2 sentences is that you can never really clean out a spot, and luck still plays a part in this game.

In a nutshell, that's not going to happen. Please read this thread. It's a long one but it destroys many myths about batteries, chargers, and detector performance. It applies to all detectors and even covers some Etrac/Explorer info...

All of the new detectors have a voltage gate. The E-Trac has a 9 volt battery and when fully charged could be 11 or 12 volts. The detector probably runs on a constant 8 volts because of the voltage gate. When the battery voltage gets down to 8 volts, the detector shuts down. There is a constant output at the coil and constant voltage for the amplifier because of the voltage gate, so it is not likely that the performance of the detector would change with battery voltage.
