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 have several types of NiMH rechargeables including Duracell. No real preference, half came with detectors I owned or own. VLF detectors are not like some PI detectors. A VLF runs at just below the battery warning level at all times. The power is regulated down to that. When the batteries get down to warning level you get the warning, and then when you get under the operating voltage the unit quits. The bottom line being it does not matter with nearly any VLF whether you use 1.5V alkaline or 1.2V NiMH. As long as you are anywhere over the warning level for as long as possible you are fine.

NiCads sucked and still suck. I can’t believe White’s still sells NiCad packs but they do.

I use panasonic  Eneloop Pro in my Whites v3i, My Whites Surf P.I Dual Field. They are outstanding even for cameras. Ni- Mh 2450 mAh. They are available world wide. I have been using them for many years  and the Whites v3i is heavy on batteries.  There  is a cheaper Eneloop which is 1900mAh both batteries are 1.2 v .

There is no better AA or AAA NiMH than Eneloops if you ask me.  The White Eneloops 1900mAh handle more charge cycles than the black Pro's, about 1500 more from memory and work well in most things.  I use the white ones in all of my detectors, I bought some of the black ones too but the white ones have been perfectly fine for VLF's....

I've got a weather station, I've had white eneloops in it for just over 4 years now and it's still sending data to my base station for it that's about 180 feet away.  It sends the weather data every 6 seconds, still on the first batteries.  It has a tiny little solar panel on it to maintain them.

MX7........very nice detector. I feed mine standard AA alkaline as I can buy a 30 pack of quality cells for less than $10. I always take them for proper recycling/disposal when they are dead. I get 30 to 40 hours of run time on one set.......so that costs me about $2.50. I’m okay with that 👍

Where do you get those, and what is the brand?

I just took the batteries that came in the detector out. It was a brand I had never heard of, Nuon, they are just alkaline, not rechargeable. They held all four dots for along time, then just recently went to two. I haven't been able to use it a lot since I got it, until lately. The Rayovac's I have are 1350 mAh...I have used them about 3 hours, and they are staying the same.

The batteries are Varta......Made in Germany.

I should mention that I’m in Australia. 30 cells for about $6 US.

Good old Bunnings is where you can get them.

The batteries are always fresh stock too 👍

      Just a heads up...  Seeing a few of the charging leads coming apart at the head. 

      Could be a batch problem as some I have seen look 100% OK  and have had some use... 

      Others seem to have started showing problems - see the 3 pics of my 2 charging heads  AND the last pic.. (not mine) is at time of un packing; and was almost separated...

      One of mine is not crash hot and the other could fail with a little push.   A simple weld will fix the problem, but will be e-mailing ML service to let them know.

      Can anyone advise me on what USB charger I should get for the Equinox 800 please?

      Just a short note on Joe’s “shorty” AQ battery. It fits well under the cuff and balance was not noticeably effected from the lighter than stock battery. Run time for me in “tone mode” was 6 hours 20 minutes. It is my understanding that in all metal it is approximately one hour less. The M12 (CTX) phones connector was a welcomed change and the power cable with a small loop and ninety degree connector also worked well. Get one of his battery set ups and avoid changing batteries in mid hunt, while they are available. I believe he has other set ups with even longer run times. Knocked it out of the park again Joe, thanks.

      I even bought the universal charger with 4 USB ports from Minelab and NEVER used anything but this to charge the machine.
      I have used it three times, I plugged it in the first night and I though it charged it fine.  I had not been paying attention and today the fourth time I took it out it flashed BF.
      Left charging all day and green light even stays on indicating that it is fully charged but when I turn it on its flashing the battery meaning its less than 5% charged.
      very frustrating, going to try another charger that has greater than 2 amps.
      Thanks for any comments / feedback

      Being a Fisher Repair center for the South East Back In Los Banos era I met and talked with some very incredible people from Jim L. President of Fisher Research Labs To a few legendary Relic hunters of that time in the south east that needed help Repairs inspiration or a pointer in the right direction...... 
            To this day I still have my Repair manuals and updates some the best electronics ever conceived Mike asked me not to sell or give out the technology .....I have always kept my word.
           I would have 3D printer or a jig and router and a one inch extension of the battery lid on the 1280x or Cz casing.epoxy or use to battery gaskets......throw in 5 gallon paint pressure tank filled with water and compress tank 90 psi no leaks good to go.....
      get rid of the connector issue In and  out of salt
      Batteries not included....due to shipping etc each customer would order batteries and charger from battery store online.....this set up 4S2P would give 7 amp hours copper 3m tape and foam  4 series times 2 parallel .
