One my beefs with the Kruzer is the battery life in the Multi Kruzer especially in low frequencies even though you get close to a full day run time it is nice not have to recharge every time your done. I went and got the external battery for it which balances the machine even better but also noticed they use the same battery pack as the Garrett AT series detectors. I think I will use my RnB litho battery on it to see how long it lasts and see if the battery life indicator shows battery life (something the standard rechargeable lithium batteries don't do). Should work as the voltage is the same, has anyone tried this before?

Just thought I'd post this............. I now run a 14.8v pack (4 x 18650 cells in series) which gives me a 7 hour run time. My previous version used loose cells in a holder but I wasn't happy with that. I made up a battery lead that connects directly to the battery compartment contacts with small brass "screw terminal" connectors soldered with 22AWG wire. A bit fiddly to hook up (long and narrow screw driver needed to tighten the two terminal screws) but very secure and + - leads well apart to avoid a short. I may put in place a rubber divider that further separates the +- battery contacts but the screw connectors are quite secure. The battery pack fits in snugly and does not move around at all. I deliberately made the wire lead long enough so the battery can be unplugged with the excess lead bundled inside the battery compartment. Tony

Did a run today but tossed in the RnB Power Pack Plus from my AT Pro into my Multi Kruzer's external back up battery case with label side up and it works perfectly. So for those looking for an extra rechargeable battery for their Kruzer series or Amphibio the RnB is a good choice. Has a really long run time and should save beating up the internal battery that comes with the machines.

Hello all I'm just wondering if anybody has taken a GPZ 7000 battery and replaced the (I'm guessing 18650??) cells? I have two battery packs both out of warranty and have some time on my hands at home due to bloody Rona. Stay safe Cheers BBB

This morning I plugged the charger into the deus and my WS4 headphones were dead, they would come on for a split second when first plugging them in but that was it and the battery indicator was completely nonexistent, I’d run them down last time out and forgot to charge them and they sat uncharged for probably a couple months my bad I know better. Couple years ago the lithium battery in my Cordless drill stopped taking a charge and after researching I found with my drill anyway the batteries had a habit of doing that and someone had found a fix that sometimes worked, trick was to rapidly plug and unplug the battery from the charger and or with the battery in the charger base do the same action at the wall plug in, the intent to introduce little power spikes into the lithium battery controller circuit tricking the battery controller into thinking there was a charge in the battery and beyond my understanding this somehow resets the battery with enough juice so it will accept charging. with my only option sending them in to have the battery replaced and with things kind of iffy right now in the world I opted to try the bush fix, took me a couple tries with 3 or 4 rapid connect disconnects and the battery indicator started responding flashing from empty to full in succession. After about 8 hours time (the first 4 hours the battery didn’t fill past the initial indication) the meter shows a full charge and the headphones seem to be working fine. someone here will I’m sure have a better understanding about this and why it worked and probably several reasons why this is taking a chance zapping the firmware, but it worked and I don’t have to send it in😀.

Just wondering if anyone has tried these? Sound and look like they are amazing and can be used with other devices that are charged by usb.

Hi all newbie on this forum from the UK anyone know which battery charger fits the Nautilus 2ba and what is the full electric specification for this voltage etc? just got a very nice 2ba machine near mint condition any info would be good thanks.

Well the Northeast has for the most part been blistering cold. Pretty much made me decide to follow new pursuits during the winter, as well as hanging up the NOX. Didn't give much thought until now about keeping battery for the Nox, headset and adaptor. Was kind of thinking every two or three months until spring. Do you people (gender Neutral) have any different thoughts on this? PROP

I seem to remember that reading that the NOX 800 required a 5 amp USB charger ? Can not find such an item ? I do a lot of battery stuff - automotive , solar , electronic etc. And generally it's referred to as C-rate - for charging batteries , the only issue from all of my experience is a lower C-rate just charges slower , but can not do harm . So what's up with the NOX 800 , I can only guess that in a manual it will say it will charge in a set amount of time ? So what's up with my memory of reading something like " NEEDS 5 AMPS " , or 25 watts .

It seems requirements around shipping or flying with Lithium Ion batteries are increasing. Either intentionally or by mistake. See this post: “Hi forum, I’m desperately looking for a good condition LI battery full size for my GPX 5000. I travelled half way across the world to do some winter detecting Arizona way and my airline refused my battery at check in; both hold and carry on were not permitted. Any one got a battery for sale this would help me out massively. Don't want to buy a new one as I’m only here for a month and can re-unite with mine back home.” Fisher Research was originally designing the new Fisher Impulse AQ with a Li-Ion battery pack but recently switched to NiMH instead for the external battery pack. It may be this decision was prompted by issues like this. It does not bode well for those traveling with large batteries in particular. On my trip to England my having a large Anker USB charger pack in my carry-on got me shunted into a separate full security check. There is a lot more scrutiny on international flights. Just a heads up for anyone traveling with a GPX detector. Integrated batteries like on a Equinox should pose no issues.

The Impulse AQ was said to have Li-Ion batteries up until recently, and is now said to be coming with a NiMH battery pack. I am guessing this is related to increasing issues surrounding the shipping and transport of Lithium Ion batteries. Especially large external batteries. See this thread.

Hello, I hope everyone had a Great Christmas and Santa was good to you. I have an old Minelab GPX 5000 from 2014. I tried firing it up and of course the rechargeable batteries are as dead as a doornail. There are three (I think they are lithium) batteries that are about 2.625" long by .720" diameter. I don't want to spend the enormous money of getting a new battery pack or having Minelab replace them. I have spent most of my life as an Electronic Technician so this would be a simple replacement for me. I am almost positive that these batteries are a 1860 Lithium, but I want to make doubly sure. I would really appreciate it if I can confirm this info. The batteries in the unit are not labeled at all. Thank You.

I'm thinking about getting a TDI sl and I have read about doing battery mods to achieve a higher voltage. This battery is only 12 volts but being li-ion it will maintain 12v for longer. Does anyone have any experience with this particular one? https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.amazon.com/RnB-Innovations-HP-3100-Lithium-ion-Detectors/dp/B00LXBWB6Q&ved=2ahUKEwju1Y3o3NTmAhX3GjQIHXcpAh8QFjABegQIBBAB&usg=AOvVaw0BCc0ZVlS3nhsHmuE0gszj&cshid=1577412259463

I need one for a project and wanted to find a cheap replacement, thanks.

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...

When hooking up to charge LED is not lighting up except with feeble glow. Charger cables and contact were checked. If not lighting up bright do I assume a faulty coil battery?, how do I know? thanks

After one year of testing my old Whites, Spectra V3i works almost 4 times longer. 18650 3.7V LiPo batteries holder, from my 3D printer, is ready:

Hi folks, so I've ordered myself a TDI SL and spent a few hrs on line trying to find anyone that ships the RnB innovations 14.4v battery to Australia which proved to be an impossible task. So I went on to try and find the highest capacity longest lasting AA batteries for the dry pack and came across the Kentli 1.5v 3000mWh rechargable lithium polimer batteries. I have to say it looks like a brilliant idea but some of the reviews I seen aren't all that great. Now being aware that a lot of reviews are probably BS of one kind or another I have to ask who here has heard of or tried these? The idea of getting a constant 12v in the machine is appealing. Would be good to see some of you electrical gurus out there put them to the test?

Just received the Equinox Charging Essentials from Doc's Detecting. It came fully charged and the power bank seems to be a solid piece of equipment. Cost $63.45 including shipping. As soon as my local park detecting sessions drop my E600 one battery level, I'll try it out. Maybe I should also buy another charging cable before venturing to remote areas. About a month ago I also obtained Doc's cover for the 600. Both sales resulted from references to Doc's in the Equinox Handbook. Speaking of the Handbook, I have changed Park1 to the Cherrying Picking settings, Field2 to the souped up version, and Beach1 to Beach for Land. The latter nabbed me a 1952 Wheatie in a hammered park.

I recharged my Nox 800 as usual 3 days ago and it took about 12H. Before it took about 4 hours in average. I did not change any items nor did I use a different socket. What came to my attention for some while is that the magnets of the charger cable became weak not holding on to the unit as they used to. I have about 100 charging cycles done in the past 7 months since I got my machine going out about 5-6 times a week. I'm curious if anyone made the same experience? I will try the other cable which came with the machine after running it flat. I usually charge after 2-3 detecting sessions (usually about 2-3 hours each session). As I have a trip to CA coming up beginning of September I don't want to take a chance getting into trouble being there. Should I have the battery replaced?

Does anybody know if its possible to use a solar cell panel to run a small electric bilge pump for a small highbanker? Will it have to be in direct sunlight ? Mine is a Johnson 2200 gph bilge pump that pulls 8 amps at 12 volts What size panel will I need and what do they cost? Can I run the output straight to the water pump or do I need a controller thing? Or can I use a panel to recharge my 12 volt ,15 amp gel cell and how long will it take? Thanks. -Tom V.

How many of you have had problems with the charger cable? I’ve had the 800 for 14 months now and both of my charger cables have died. Have any of you had this happened to you and were they replaced under warranty? Thanks Oscar
