The F5 manual says use "9-volt alkaline batteries only", but I see rechargeable Nickel-Cadmium batteries listed for use for the F5 on various retail websites. Any insight on using rechargeables with the F5? What type of rechargeable battery works with the F5. Or should I stay with the standard alkalines. Many thx.

The manual says that for a reason. They dont usually give as high of a voltage output as alks do. That may be why.

POWEREX MH-R9V True 9.6V 230mAh NiMH Rechargeable Batteries
* 230 mAh
* Ni-MH
* Battery Voltage: 9.6 V
* Feature: Actual Voltage is slightly higher than standard 9V Alkaline Batteries. Will outperform a standard 9 volt rechargeable battery due to the higher voltage. PowerEx 9.6V 9V batteries will operate paintball hoppers and wireless devices that other 9V rechargeable batteries cannot power. Enables wireless microphones and paintball hoppers to last longer and work faster.
Powerex are extremely high quality. (my opinion). They are not cheapy junk and cost a little more than others. "Most" of their batteries are actually manufactured in Japan, not China. I use the C cell versions in my older White's unit. They last forever. Hold their charge like you wouldn't believe. Way better than american branded (made in china or some other funky place) rechargeables. These should have the juice to power your unit. They carry a 1 year warranty. My 2 cents worth
Now don't make the mistake of thinking of going to a higher mAh version is better:
example: "Maha MHR84VI 1-pack 250mAh 9V Ni-MH Rechargeable Batteries"
These will only actually push 8.4v, thats why you need True 9.6 volt version I first listed

I wanna check into them!
Thank you for the responses ths far. I agree that you should adhere to the manual, but it gets confusing when you see sights such as KellyCo advertise the below Pro Series charger as a F5 accessory. Along with other website retailers throwing in a free rechargeable 9V when you buy from them.

It's all about how much real voltage the battery supplies. Get the right battery..you will save a ton of money. Get a underpowered battery, nothing but problems....seen & unseen.
FWIW, knowing about battery voltages and how they really perform in electronics was part of my employment responsibilities.
And dealer supplied batteries do not guarantee that the proper batteries are being used, especially if the batteries are aftermarket and not from the metal detector manufacturer.

I tried the rechargeables in my detector. Yes, they work, but, what you will find is that they will not last as long as the alkalines and they will go from beginning to get weak to stone cold dead very quickly. Alkaline batteries will fade very slowly, so, you will have ample time to hunt before changing them. If you don't mind changing the batteries often and carrying a supply, then they may work well for you!

If you get high quality NiMH batteries, like Powerex, the phenomena your describing does not occur. What you are describing is what happens with old technology NiCad (nickle cadmium) batteries. New NiMH batteries need to be charged a very specific way before first use so that they run at full capacity. Do some internet research on this.
Gotcha Terra and I know what you are referring to. I did get some Nickel metal hydride, and properly charged them. Additionally. I got the highest amp/hr rating batteries I could find. These were the 9v's that go in the Bounty Hunter Pioneer 505 and did the same thing with some AA's for the F75. Up to this time the alkaline batteries would last a long time......no I didn't keep notes, but, many hunts were made. When the NiMh cells went in, the usable service was cut, at least by half and when they tell you they are getting low, it means they are not long for the world,,. When they get the Lithium Ion batteries for the detectors, I'll try them again.
