I've successfully removed 9V batteries from my Garrett Carrot (which now uses AAA batteries) and I've started on the process and getting rid of 9V batteries in my Fisher F2.
I've taken the approach if trying to use a single battery to power the F2. A while back, I read from somewhere that the F2 ran off two 9v batteries running in parallel. However, this means that if I use a single battery for the F2, it should work (assuming the single battery has the ability to provide the necessary current). But when I try to use this set up, my battery gets warm. I eventually realized that the Fisher F2 is NOT using a "pure" parallel setup. If it were, it would not be creating a short circuit in my single power source setup.
So my question is: how exactly is the Fisher F2 power wiring arranged? It's not parallel and it doesn't appear to be in series, either.
Any insight would be appreciated.

What kind of batteries ya'll use? I used to buy nothing but Duracell rechargeable, then in the last year I couldn't find any. I just bought some Rayovac with a charger, but they don't seem to hold a charge. I charged them, put them in, they showed full charge as I hunted for about an hour, then the next day only see two dots on the power gauge. I recharged them hoping they needed a break in, but they did the same thing. Now I have used them for 3 days, with only two dots showing, they don't seem to be going any lower, but I don't trust them. I just did a search and found a bunch of Duracells, I might of been looking for the same charger I used to have, that died, and couldn't find it. I hate to go spend more on a different brand...I didn't notice until now, the rechargeable's are 1.2 volt, whereas the regular are 1.5 volt, would that make a difference?
I don't want a battery pack, at least not a NiCad...
I seen this issue on the oz forum...is anyone besides me having a problem with the 12v charger for the gpz?
I have two- one for my ctx and one for the 7000 and they both behave badly...when I plug one into the 12v outlet in my truck it starts flashing red while charging. The manual says this means there may not be enough battery to pull juice from the truck battery...my truck battery is brand new.
So, I carry a small invertor and plugged that into the 12v outlet, then the battery charger into the inverter...the charger worked fine but my truck battery was drawn down and I had to jump it...
so, the second question is this; does the inverter draw a huge amount of amps to go from 12v to 110v to charge a the zed battery???
Also, is the sensitivey of the minelab chargers adjustable ????
Got sick of buying 9v batteries for my Profind pp. Blackube just came out with rechargeable 9v lithium batters that have the same voltage as an alkaline. A little pricey at $25 for 2 but the PP no longer falses out when put on it's side then turned back up. This used to drive me crazy. Batteries put out near full power until they run out instead of fading in power like alkalines do.
IMO worth the few extra bucks.
Did a run today but tossed in the RnB Power Pack Plus from my AT Pro into my Multi Kruzer's external back up battery case with label side up and it works perfectly. So for those looking for an extra rechargeable battery for their Kruzer series or Amphibio the RnB is a good choice. Has a really long run time and should save beating up the internal battery that comes with the machines.
Hey All, Measured White's TDI SL factory battery packs and discovered the following differences.
NiMh Battery - HD #802-5321, 2200 mAh.
After full a charge, one day later..........................................10.99 VDC AA Battery Holder - #802-7150, 8 cell.
With Nuon Industrial Alkaline from White's Factory............12.94 VDC With Member's Mark Alkaline from Sam's Club...................12.96 VDC With Energizer Ultimate Lithium...........................................14.46 VDC
Was very surprised that with Alkaline batteries, the tested voltage was higher than with the NiMh battery pack.
Also, the NiMh battery pack seems to drop about 0.05 VDC a day.
But the clear winner are the Energizer Ultimate Lithium batteries at 14.46 VDC!
