I know it is ok to use the 3030 battery in the GPZ. Is it ok to use the GPZ battery in the CTX? I am thinking the larger battery would help with balance when using the large coil. Any thoughts? Norm

Anyone know of any 1.8V AA rechargeable batteries with a high mah for sale? Trying to find something hotter to use in my TDI SL. Or how to go about using 4 of the Panosonic 18650 3.7v 3400mah batteries in the 8 battery box? Still waiting for Whites to have an upgrade available.

We have some detectors that have a battery pack that has to be charged in the unit and others that can be removed. The only thing I dislike about the batteries that can't be removed is when this happens you don't have a working detector anymore. I know most have a long charge life but all have a limit on how long that will last. Now give me a detector that a battery pack that can be removed to be charged and have a pack you can drop in to keep detecting is in my opinion is the best way to go. I'm sure everyone has their opinion and I'd like to hear yours. Chuck PS At this time I have just one Scuba Tector that batteries can't be removed

There appears to be a new genuine by Minelab smaller battery option available for the GPX series. Oddly enough it is not on the Minelab site and no reference to it anywhere except one Australian dealer http://www.minersden.com.au/minelab-gpx-small-lightweight-battery/ Part number 3011-0332 and less than half the weight, 18.6 wH good for around three hours.

Does anyone know the part number and or the manufacturer of the connectors on the end of the Minelab gpx battery cable ? It looks like a common 5 pin mic cable. I make my own cables have so since the sd's. Thank you Kenny

however, being somewhat 'thrifty' I have often gleaned over the thought of using a rechargeable alternative. My brother, who is thriftier than I, not long ago told me about rechargeable alkaline batteries and their abilities. I have experience with both the normal NiCd and NiMh rechargeable varieties each type having their pros and cons and the biggest being the lower operating voltage when fully charged of about 1,2 volts. Alkaline in my experience initially will be in the 1.6+ voltage range, much better for my LST and GM4. I guess my question might be, why did the Rechargeable Alkaline alternative never get advertised or promoted? I believe they may be a worthy consideration but, " anyone out there ever go this route?"

Wondering if anyone's using the GoldScreamer power packs for their gpx? Thinking I may have to go that route very soon....if you do how do you like the system? Has anyone had any bad experience with using it as its not an official minelab battery.

If you own a GPX I'm sure if you don't already have a battery back up you are probably wanting to get one. Well, that's where I am at. Problem is buying a 2nd battery is some 400 dollars or more. I know Doc's has the Screamer kit with the amp and a couple smaller batteries etc which don't sound bad but it's still over 400 dollars for the complete set up. There may be some other similar set ups as well, I don't know. I could see the option of buying the Screamer amp for 135, the little pouch that goes around the detector for 50 and another 50 for one battery cutting the cost a bit. But then you need a different charger for this battery so probably another 20 or so bucks. So with shipping your probably better than 250 for the set up. Some say the screamer amp is plastic and can get cracks in it easily? I'm assuming too the screamer has a built in regulator but I don't know. Anyone have experience with using the stock minelab set up VS the aftermarket one's?

Part of this in is for jasong with his recently acquired FisherScope T-30, battery setup. Plus, a sample of some neat FisherScope models all in working condition with the exception of the MA-two box. Plus, What may be the first White's Gold Master and auctally maybe the first model they made under OreMaster before becoming White's Electronics. Jasong, the first two pictures are of two FisherScope T-30 models, one stock with the original battery the other modified with either a 9-volt or 12 volt battery pack. They work with either 9 or 12 volt setup, go with 12 volts if you prefer. Use the attached pics to determine which leads to solder the battery clip, then make sure the battery is secure or covered to prevent a short...... Plus, You'll need the older headset to plug in to power on the unit, or the plug in vintage speaker I believe yours has one. Current headsets will not work, needs to be the older vintage type. Ok, Moving on with the White's Gold Master. It is powered with one 67.5 volt pack and two 1.5 volt packs. Until a few years ago, the 67.5 battery packs were available on the internet. But recently, they stopped making them. Someone out there started making a neat setup which resembles the original battery and has same battery clip setup. Using seven 9-volt batteries in series they came up with a cool setup which slides into a cartion for those needing 67.5 volts to power old radios, Metal detectors and such...one of the pics shows the 1950/1960's FisherScope T-10X and the BFO Gold Master, Both use the same 67.5 volt battery pack. And both use an additional set of 1.5 battery packs. In case someone wants to power up an old piece of vintage equipment, several sources are out there to provide the type of voltage needed. Hope this information helps. These are a sample from my collection, and with the exception of the Gold Master these are different types of Fisher Scope models. Several with painted wooden coils, And some are extremely advanced looking for their time. Jasong's T-30 was one of them, only drawback was it's an arm killer to swing. Thanks for looking, Paul

I seen this issue on the oz forum...is anyone besides me having a problem with the 12v charger for the gpz? I have two- one for my ctx and one for the 7000 and they both behave badly...when I plug one into the 12v outlet in my truck it starts flashing red while charging. The manual says this means there may not be enough battery to pull juice from the truck battery...my truck battery is brand new. So, I carry a small invertor and plugged that into the 12v outlet, then the battery charger into the inverter...the charger worked fine but my truck battery was drawn down and I had to jump it... so, the second question is this; does the inverter draw a huge amount of amps to go from 12v to 110v to charge a the zed battery??? Also, is the sensitivey of the minelab chargers adjustable ???? thanks fred

Hi , Could someone point me in the direction of a decent set of rechargable batteries for the 2300.... i have the charger i got with it... i threw the batteries that came with it away....

I have a claim that has lots of very tall thick brush. Tired of getting caught on all the branches. So I ordered a Gold Screamer battery kit for my 4800. Since I am very protective of my GPX I thought I would ask for reviews from others before I used the Gold Screamer. Anyone have any problems using it with there GPX? Thanks in advance. Steve

Anybody try this is it new? Any info? https://www.reedsprospecting.com.au/shop/detail/eq-spirit-battery-special/ From https://www.reedsprospecting.com.au/shop/detail/eq-spirit-li-ion-battery/ : This battery is designed to function with all of the Minelab "gold" detectors. Voltage can be adjusted to suit each type of detector. It is possible to use the battery as standard, but it is recommended that you attach the battery to the detector and run it using the Wireless LINK. The headphone or speaker jack is inserted into the LINK and the detector is free of cables. The LINK and the battery are re-charged separately. The sound quality of the battery is very high. The battery is re-charged with standard Minelab GPX chargers. If you need to buy the chargers when you buy a battery we are selling the chargers at $60.00 for both the 12V and 240V. There are Noise Cancelling Headphones that work with this battery as well.

Has anyone heard of these batteries? If so, where are they available? I read a thread on Findmall (White's main detector forum) and it sounds like these batteries can give an edge to a detector. Also, it is claimed they last a loooong time.

Ok I got the ring thing. Now I'd like a few spare batteries. Don't like using my CTX half day ones. What do you think we will see first, the batteries or a coil?

Looking to buy rechargeable 9 volt battery`s. Wow a lot of options out there and I am clueless on all of it. Any suggestions on battery type and brands. Also is their and difference on the chargers? Seems the more I search the more confused I get. HELP.

Very interesting advance.

For a long time the standard in VLF detectors was 12V operation. Eight AA cells, perhaps still the best example being White's Electronics and their AA battery pack. There are a few detectors running a single 9V battery, like the Gold Bug Pro, but they are pretty rare. Tesoro is the main proponent on a few models. The new standard is 6V or four AA cells. Many examples there like the X-Terra 705, AT Gold, or FORS Gold. Now we have the new Fisher F11, F22, and F44 running off two AA batteries. 3V operation. There is no direct connection to battery voltage and depth in modern VLF detectors. In general I have always looked at more battery mass as simply meaning longer battery life. But even that appears to no longer be true. New low current designs are getting good running times out of fewer batteries. Nothing earth shattering here, just a general observation. The main thing we are seeing is the overall reduction in weight possible by using fewer batteries. Just a FYI. The main drain on batteries is the detector speaker system. Number one way to boost running time? Use headphones.

I have never used many rechargeable batteries before,just wondering what you guys think may be the best and longest lasting of the many brands? I will mainly be charging C batteries for sdc 2300,and also some 9 volts for gold bug. I lost track of the thread that had some of this info. About recharging, and solar chargers. Thanks guys Rick

I want to make a external battery set up for my GPX 5000. I already have the correct 7200 MAH LiPo battery. I purchased an external headphone amp from Jonathon Porter. (JP) What I'm having trouble finding is the 5 pin male CB Microphone plug. And after I find one, how do I wire it from the LiPo Battery . I have Deans plugs and wire to go the 5 pin. But the battery has a + and a - , the 5 pin has (of course) 5 pins. So which pins do I wire to. I don't want to fry my GPX 5000. Any input appreciated.

Hello all, I have been assigned to ask just how you guys out in the field recharge your batteries for your Minelab SDC 2300 gold detector? I am really curious, as I saw one of those new detectors in a box, and it had separately, not in the box, a off the shelf charger with standard 2 prong 120v. plug end. Aside from having a portable generator, or an inverter, how WOULD you charge your rechargeable c cell batteries? The rest of the Minelabs had a 12v plug that would work in any 12 volt plug in a vehicle, but this one has me stumped a little. I know there could be others that will be curious about this in due time... Thanks for setting me straight, as most times in the field, I don't have a current bush to plug into. Maybe I am missing something somewhere... Have great day! Gary

I try to use rechargeables as much as possible but use alkalines for backup and around the house enough it seems I always have these batteries sitting around. I usually replace batteries in my detectors well before they are dead, so keep them to use in flashlights etc. until they really are used up. I decided I needed something simple that would test any size battery with no fuss to sort out the good from the bad. I've been using a little multimeter but wanted something simpler. I found the La Crosse battery tester on Amazon and it has been perfect for me. I rounded up every loose battery I had and it makes it very easy to just drop them in and test. AAA, AA, C, D, and 9V are all easily tested as good, bad, or somewhere in between. At less than $10 for a pocket sized tool it has been proven a real bargain for me. Anyone else got a great battery tester to report on?
