I just use Energizer 9 volts and they seem to last quite a while. I bought a bunch of them in bulk on &$#.ay for a pretty good price. Duracell should be good too.





Current detectors:
Tesoro Bandido II Umax (2)
Tesoro Outlaw
Whites MXT Pro
Minelab Equinox 800
Whites Beach Hunter ID 300

That can be tricky choosing. Unlike other sizes of batteries not all 9 volts are the same size. Many are taller than others.
I use Duracell because they aren't as tall as some others.
I made the mistake with my tesoro 8 of using utilitech and other batteries in it and it's now permanently compressed the battery terminals.
If I do use a Duracell or Energizer now in it I have to put a folded paper shim at the bottom or it doesn't make contact with the terminals and is loose in the compartment.
I got li ion 9 volts but they are also too tall. They now go in smoke detectors lol.
If you have a Duracell or Energizer, even if it's dead, save it to compare to others you may find and you'll see what I mean about height difference. I was very surprised to see the amount of variation in size between different brands.

I tried 9 volt NiMH batteries in a CZ.

I got about 4 to 5 hours of use as opposed to 15 or so with alkalines (brands make a big difference.)
And rechargeables will self discharge in storage--Stored at 70 degrees F (20 C) NiMH batteries will lose up to 40% of their charge within a month
Alkalines not in use lose about 1% per year.

I use Tenergy NiMH and EBL Lithium Ion rechargeables in my Cibola, Minuteman, F19 and Garrett pinpointers. I have not experienced much storage loss, certainly not almost 40% on good quality rechargeables.
I have some rechargeable batteries that are at least 10 years old that still fully charge and work fine. I just carry plenty of charged spares either in my pouch or car.

First, re-read the reply by 'Stoof-tabsallday' for the biggest precaution to take. Many people haven't and it often results in problems, and that is using any battery that is over-sized. Oversized doesn't only mean the battery's length, but also the width and thickness. If over-sized a battery can over-compress the metal battery terminals in the 'drop-on' types. Being too large can also wedge them in the battery compartment, or make it difficult to slide on a battery compartment door. That can result in a cracked / broken plastic door, or wedge a battery so tightly it needs to be pried out.

This can more often happen with a rechargeable battery, but I have seen it too many times with some alkaline batteries as well. You should never have to force a battery into position.

Now, by 'quality' I am, not referring to any specific brand, either. Some batteries are what we might call an 'off-brand' meaning a bulk production or just not long-standing, well-known name. Some are a 'house-brand' battery made for a particular business. Then there are some major names that have production facilities in different parks of the world, and while some do produce a well-made battery with very reliable 'run-times' and performance, there are also many that make an inferior battery. They might be a lower voltage, or have a more variable voltage out of one package, and just not provide an ample 'run-time' .... even though they might have a higher retail price simply because the package has a popular brand name.

So, learn as you go. I don't always make a decision based on where the packaging says a battery was made. But if I find a battery that is not very impressive, I remember the warning signs and don't buy it again. I just remember those that do work Okay, and then I shop for a better price so that I get the best 'run-time' I can at a more affordable price. For example, about October or so I went to the local grocery store. A 'Thriftway' family store that carried Western Family' house brand items, but they had been bought out and the new company, I believe it is called Food Club, had their house-brand items repackaged. As I walked past the Customer Service counter I spied a price-tag on the battery display that read, in big bold numbers, 99¢.

Yes, that was for their 9-Volt Alkaline Battery! I had an extra $10 so I bought 10 of them, but that was just an unadvertised 2-Day sale, and I went back the next day and they had been cleaned out.:( I've used them before and I knew thy were a proper physical size, and they provided decent performance, so I bought a few extras for my Emergency Battery, Flashlight and Radio Tote,

Just make sure they are a 'proper-fit' size, and alkaline, not a standard or heavy-duty battery. Then be alert for any weak-performing batteries and avoid them in the future.

I've been using the Powerex 9.6V, 230mA NiMh rechargeables and find they work really well. They're "slow discharge", so retain their charge for a long time. Size-wise, I haven't noticed any issues with them fitting into the battery compartment.
