I don't know why not. Based on using them in other devices you should get much longer battery life. If the higher price is not a factor, go for it. Alternatively, a good set of rechargeable batteries might be cheaper for you in the long run.

The F-75 uses standard AA 1.5v batteries.
I own an F-70 which uses the power source and battery compartment.
These two detectors will also run on the 1.2v rechargeable batteries.
Don't mix battery types!

Now, back to your question!
Its my understanding that the lithium batteries our designed for either higher drain devices or longer term uses such as Heating/cooling thermostats. But, they are still only 1.5v per cell.
If the batteries in question are the standard AA size and are in fact 1.5v and you don't mix them with other battery chemistry then there is NO reason for them to not work.
Higher current ratings does NOT mean that more current is forced into the electronics, the voltage is the force and the current is its reserve available power.
1000ma @1.5v will not have the operational time at the same load as a 2000ma @1.5v

My best bang for the money for ALL of my detectors has been the rechargeable "Tenergy Centura" LSD Nickel Metal batteries.
They have a very LONG run time!
The are the LSD type (Low Self Discharge) so they have a really good shelf life! So 8 of them gives me a set to run on, and a backup set to get me back home!
With the rechargeable's I'm thinking that I may not have to by anymore detector batteries for YEARS!!!!!!!
I get the Tenergy's at either batteryjunction dot com or amazon.
They're other brands that I'm sure would work well also, but I wouldn't recommend the Rayovac brand!

And to note!
No! the lower 1.2v of the rechargeable batteries does not reduce detector performance due to the electronics using internal voltage regulators of a lower voltage than the source voltage.

Same for me, MarkCz's brother Ron. I hunted all last year with the same 4 batteries, I would charge them the night before a hunt and use them all day and I was still ready full charge at the end of each day.

So I didn't have to worry about batteries the whole summer, just charge and go.

What I do is a little different than Big Brother, but its not better or worse its just a preference, but I start out with with 8 charged batteries, 4 in the detector and 4 in a little storage box with me as backup. I will leave the originals in the detector until they go dead, (or several months) and then when they die I swap them out with the backups and when I get back home I recharge those and pack them up for the next backup set of batteries.

Another trick I used to do is when I only only had one set of rechargeable's is I used regular cheap Alkaline batteries for backup, and then recharge the rechargeable's when I got home and once charged I would put them back in the detector and put regulars back for the next backup. But you have to monitor the backups because they will in time go dead, so you almost always have to have a couple of sets of backup batteries.
Before the LSD batteries came out was another reason for the regular battery backups, the early Ni-Cd and Ni-MH ones didn't have enough shelf life to use them as a good back up because every week or so they would just go dead, or you would get 10 minutes of run time out of them.

Yes, they will work. A little over two years ago I purchased a battery charger called 'Chargeit! from eBay (just do a search)and started re-charging my alkaline batteries. It works beautifully! Even the cheapest alkaline batteries will recharge several times. This battery charger has saved me tons of money! I get my metal detecting friends to give me their used alkaline and use them. Believe it or not, the worst batteries to recharge are the copper top brand. Also, sometimes there are a battery or two that will leak after charging and sitting so inspect them every so often. Otherwise, I am very happy with the charger and it also has 2 usb ports for charging on the front of the unit. My only problem with it is that it does not have an on/off switch but I purchased a cheap power remote that does great.

Well, "moose" have you come to a conclusion on your next battery purchase? :smile:

I think that moose's disappearance may mean than he's been off taking vocational battery class 101 :detecting:
