My Equinox 800 no longer charges, the green light flicks on and off as if its doing its job but the battery is not holding a charge.. as soon as i turn it on i get the 'battery flat' sign.. I'm one of those pedantic bastards who always runs their battery flat and then fully recharges it, for fear that otherwise it'll create a 'memory' half full.. 

Is there anything I can do about this? or is my poor old Foxy Noxy a write off? 

Any advice will be much appreciated.. even slaughtering a black chicken at midnight during a full moon, if it works I'll be a very happy man!

Ehhhhhh... Lithium ion batteries don't have much magic to them. They either charge or they don't all of a sudden. I've always been advised to never let them go below 25%, been using them in other devices for years, and I have had a few kick the bucket. Some just... stop.

So ya got a few options. If the machine is under warranty, great, but you may have to part with it for a while. If it isn't you can get a replacement battery and replace it yourself. There are a few videos out there that will show you how. Be careful about sealing things up right. It may not be "dunkable" unless you pay strict attention to o rings and such.

The Equinox may stand alone or is one of the few machines that can run with an external battery attached via the charging cord, get a Power Delivery (PD) backup battery and attach it somewhere (velcro?) plug the detector into it and go. They are pretty cheap, and a 15000mAH battery will last 3 times as long as the installed battery. Anything bigger than that would be just too big. even a 5000mAH will give you the same life. I have found my detector didn't charge once and ran the battery out, I just taped the biggun' to the shaft, plugged it in, and started swinging. The extra cable is a bit fiddly. You will notice the additional weight as well, and you can't get the battery wet . The reason I mention PD specifically is twofold, they have a USB C receptacle and most charge things much faster than a "standard" backup (USB B)

At least you can use ol' Foxy Noxy until you get a replacement battery.

Try cleaning the contacts with alcohol where the charger attaches. One of them might be dirty.

Most devices have a battery monitor circuit  that shuts the unit down before the battery gets too low to accept a charge.   The PD battery may "jump start" the battery to get it charging regularly again but if not , going with a new battery isn't too hard to do. I have a small PD battery I carry as a backup in case the built in one dies before I do !  Oh My Goshk !  Haven't needed it yet but will also work on the cell phone , headphones or whatever else needs charging.....

Maybe someone will come out with one of those sun shade hats with a built in solar panel that can keep the detector fully charged as long as there is sun shining ???  LOL

I think abenson is on to something here. Of course I took the long road, I'm a noob. The one time my 600 didn't charge I swear the green light was flashing, I always plug it in at the end of the day. I "may" have wiped the contacts when I connected the PD battery as a reflex.

Nevertheless, if you are like me and find yourself out hunting 5 hours or more, you need a PD battery in your pocket or pack or bag. I hated having to quit when two of the three bars were gone.

Thanks for your advice F350Platinum (and others), but my Foxy Noxy was bought second hand (like all my detectors).. I'm thinking about pulling the battery out of my Nox 600 and putting it in the Nox 800.. and just share it between the two.. I've seen the videos on youtube on how to replace the battery but I can't find that particular battery in Oz..

Yup yup , If you have a 600 . Switching the batteries and trying charging both will tell you if its the battery or charger circuit that's giving you the problem !

Might be worth just sending it in for a new battery and tuneup. Risk of getting some off brand battery and toasting the whole unit + labor and effort vs tossing the control unit in a box and let them deal with it is something to think about.

Would be a different story if the company was no longer around.

      My battery in my Nox  is fine.  I pursued ordering a battery.  Just for a spare and to seek out the process so I could share with folks.
      First I called number 1-877-767-6522 (Minelab customer service) and talked to lady named Julie.  Julie referred to the following number in PA - 814-283-4270 (Minelab repair center).  I called this number and spoke with gent named Dan Diehl.  He stated I was actually the first to buy Nox battery. He while I had him on phone had just realized the batteries were at their facility for sale.  Price is $30 USD.  He said total price including shipping was $39 for a nonsignature required usps delivery.  I used a credit card.  And that’s it.  So the number above for Dan is the number to call to buy battery for Equinox.
      As a side note I inquired about their repair backlog.  He said they were in good shape.  With only about a week of backlog repairs on hand.  I asked this due to possible lasting effects of Covid 19, plus I wanted to be able to share with folks accurate info.  In case some were not sending in their units for repairs fearing long wait times.
      Cheers

      The 24k was relatively short lived by comparison of other US made detectors that seem to hang about on the market for 10 to 25 years, being a US detector it was a bit difficult for me to ever get my hands on one and I guess I was just too slow at making the move on one.  So I'm considering an alternative.  I like my Gold Monster but it is a bit simplified and I prefer more options so I just use it as a pinpointer, at the moment my primary prospecting VLF is the Equinox, I rarely use anything else.  I have a Gold Bug 2 but find it a bit primitive especially with features and I'd prefer a detector with Target ID's and the tiny gold improvement over the Nox I find is very minimal, the Nox has a great range of features and does a pretty good job but I'm wondering If I'd get a bit more out of a dedicated prospecting VLF with a higher frequency.  Am I losing much not using a 24k and sticking with my Equinox?
      The Nokta Gold Kruzer seems a viable choice, it's extremely cheap and sitting in stock at my local dealer, it has Nel coil support which I absolutely think is a major bonus, the Nel snake coil is made for it, and to me this seems the ultimate prospecting coil. I have it for my Fisher Gold Bug Pro but that detector just doesn't cut it for depth on small gold for me as I live in a place with a majority of the gold being very small.   I need a the best VLF for hot rocks possible.
      Why is it that Nokta detectors just aren't as popular, they seem to make a great range.  The Gold Kruzer and Gold Racer are what people have wanted in VLF prospecting detectors, aftermarket coil support, features dripping off them, quality builds and water proof and so on yet you don't see them as detectors people are using.  Why is this?  Steve H had a Gold Kruzer, Gold Monster etc, etc.... yet ended up settling on the 24k instead.  Is the 24k that much better than the Nokta?  What made the 24k the keeper and the Nokta the one to go.
      Would I be better off waiting to see what Garrett come out with, with any luck Nel will make coils for Garrett's version of a 24k.
      I've never owned a Notka, I am a bit puzzled why they make such feature packed and on paper great looking detectors yet people aren't using them.

      I spoke with Martha at Minelab this morning. The reason I called is, my machine is out of warranty and has been replaced three times since I bought it. I wanted to know how much it was going to cost to replace the pod and if the replacement was going to have a warranty. She told me it would cost $350 for a new replacement, or $225 for a refurbished unit. What she meant by refurbished, if someone returned a whole detector because of a faulty coil, shaft etc, they would send out that control pod if there are any available. I am still waiting to hear back from her on the amount of warranty that will come with the replacement pod. She wanted to double check on the amount of time before she gave me an answer. I have her permission to share this information on the internet forums.

      Some folk believe that their prayers are rewarded, others claim that if you ask the Universe for anything it’ll respond.. But when you need a new battery for your Foxy Noxy, these methods don't work anywhere near as good as keeping an eye out on Ebay..
      Since that awful day last month when the battery on my Nox 800 stopped charging I’ve considered many options, including an external power-pack (expensive), soldering the plug-in cable to other lithium batteries (deadly), and to keep on swapping with the battery from my Nox 600 (pain in ass)..
      This afternoon I searched on Ebay and scored two new Equinox batteries for just $50 (plus $10 postage).. That’s a new battery for Foxy Noxy and a spare for the unlikely event I ever need another one! Gotta love them win/win days..

      I stumbled across this video of the F75 finding a silver coin deeper than the Equinox, and then he goes on to show the F75 performing better finding a coin between iron.
      What are your thoughts on this one? I never did bother buying a F75 even though a SE edition came up for sale extraordinary cheap nearby to me, my experience with my T2 had me thinking my Nox was better in almost all situations, was I wrong?    I'm a bit puzzled by this video and I guess it could be soil conditions or something but I've found my Nox far better on deep silver than my T2 and I sure have experimented a lot on untouched in ground silvers.
