I was using The Explorer charged up the Batteries last night rained out today and then went for a little night hunt under the lights at a City Park,I am using these new settings and in first few swings a nickel on top of a 1952 Rosie,I got lucky because I was running Ferrous tone and it was left and low holding but I was thinking it was Silver being masked because it locked towards the bottom.Yeah for me another silver four for the year.But I am not to excited about that now I was when I found it but I stumbled onto something here just maybe.I was running the unit and it ran like I never had it run befor like when I first got it,but as I was running it here it goes the battery started to drain a little I was running the light on and then a little more it was going down I started getting the bounce bounce all kinds of signals and it just wasn't running smooth anymore.I am thinking dang this you know what.I wen t back to the same area I just hunted when it was smooth operating and it was doing all kinds of readings,Now I am thinking what the heck gives here.I am by know means stupid I can only give you my post and inputs by what I have been using but I am betting my bottom dollar that this dang unit has a bad battery pack and doesn't put out the right amount of what ever volts ohms this is where the TECH HEADS come in to play.I didnot have my Battery pack with me the spare so I will try it tomorrow on my big hunt and bring my back up for it.If this thing isn't getting enough juice will it start acting goofy is my Big Question.
 
are in the sealed unit anyone wear a sealed set out and take it apart to see.Are they China Batteries
 
was to excited about my maybe discovery of the battery pack.
 
Just a voltage regulator or something, I forget. They are the industrial batteries with the flat top and bottoms. Chinese. I have pictures of one apart I will find in a second and post.
I run mine till it shuts off from lack of juice. Not all the time of course but I have been out and not wanted to stop, etc. Never noticed anything different.
What kind off battery life are you getting from one charge? I can get a bunch of hours, if yours drains very fast it is toast. Do you have rechargeable AA's? Guvner has a link to a guy that sells some good ones. The Sanyo's are about the best I have heard. I have some green ones that do not say Sanyo but are supposed to be. I don't think they are as high of a mAh as they are supposed to be. I just did a search on ebay and it looks like there is a 2100mAh out now! Guvner said he gets an ungodly amount of hours out of his 1800mAh AA's. Way longer than the factory pack anyway. The factory batts are 1200 or less I think. I never have used my green ones in my detector, only my camera. I have like 4 battery packs that I have won and came with my two detectors. One is brand new never used and dead as a door nail! Will not even turn the detector on then right off after 10 hours on the charger. My original battery pack I have is serial number 00006 and is the one all apart because I dropped it on concrete. It did work better than my new ones, but I have never glued it back together yet to see if it still does.
You just might have a bad pack. I think I can get 10 solid hours out of mine. I think more but never really timed them. Of course the back light suck more juice.
 
I guess they are 1500's. <IMG SRC="/forums/images/biggrin.gif" BORDER=0 ALT=":D">

If I go out tomorrow and this happens and then I put new alkaline in and that fixes it.Everyone who picked on me and thought I was a ANTI-Minelab GUY say sorry to me....LMAO...just teasing but I will almost bet my Explorer that is my problem,Has anyone had a problem like this or am I the first to stumble onto this,not likely I am not that smart.I did just get off the phone with a Soveriegn user and he said that when the amps drop his wont work right.I bet I have a bad battery in my pack.I will find out tomorrow and if it is Minelab can have this one and send me a new one.I think they will do that to just hear me stop complaining...lol...but really I am here to tell you what a difference it made I usually charge my unit when it gets down to 1/4 then I plug it in.
 
I never used my light befor until tonight and I usually only get about 6 hrs befor having to recharge it.I guess I am going to get some 2100mAh or the 1850mAh they have out now.I am also sending this to Minelab and bring it to their attention once I confirm this in the field tomorrow.That if I am to pay a thousand dollars for the unit could I have some good American made Batteries instead of the Chinesse ones.Anything to cut a corner.
I know how to do a battery drain test on my trolling motor batteries but wonder how you can check these things,I guess goto radio shack and ask them for test equipment.I swear if it comes down to my battery pack being faulty and I did all this belley aching for nothing then I am sorry and mad.Mad that knowone else figured this out or didn't tell me about it...lol
 
I noticed in cold weather my factory pack only last for 6 to 8 hours.
I got the rechargable 1850s from www.ripvan100.com bought 16 of them so as to have a backup set and I got the charger for them that I can cycle them all the way down now and then.
I get 16-18 hours per charge in 30-40 degree temps
look for the web special if you want to know correct prices.

I am just waiting for someone to say this thing will act crazy if it is not getting enough ump from the batteries.I noticed it do this befor but it didn't dawn on me till it happened a second time and all the trouble I was having with it.I can see why the reboot process would work with mine because like anything with a low battery take it out and turn it move it and it gets a better contact and runs better for a bit.The battery pack for the removable batteries had a spring to long and I couldnot fit the batterys in the dang thing I ended up cutting the spring some so it would fit,just more hassles but like anything i will get it weeded out.I don't have anyway togo but up from here.
 
Rick,
I have had one guys Explorer that had a bad pack, but acted differnt, his would get very unstable at time and then shut down. I have the Sunray Super charger and discharged and recharged the pack and it seem to be fine, but after a hour or so you could see the gauge lower than normal. If you opened the battery door up and pushed on the battery the gauge would go up to full, so I thought bad connection and cleaned it, but it still did it, so I gave him a new battery out of stock and tried the battery pack in my Explorer and it worked fine for a couple of hours and did the same to my Explorer. Minelab replace the pack for me with no problem. I feel their was a internal problem with the battery pack being I could push on it and it would be fine.
One thing I would recomend is a Q 12 charger of Sunrays as it will give a perfect charge everytime without over charging. If you have one of these than I would get some of the 1800 Nickle hydrides for the alkiline pack as this charger will charge them and you will have a extra rechargeable to put in while the stock one is charging.

Rick,
Mine does the same thing when the battery indicator drops. I only get 5 to 6 hours out of a charge. I always carry a spare battery pack and it fixes the problem every time. Only once did it forget the spare battery pack and I was making some good finds and had to leave. It about killed me because it was back to work the next day and had to wait a week to hunt there again. I think the circuit board is used to keep the batteries from over charging because you would not need a regulator since the output of the transformer is 12 volts.

Thanks for the site I have some friends that are into RC airplanes that buy them by the hundreds pretty cheap. Dynacharge 1800 mah. I have got 16 of them for 10 bucks but I need to get a charger.

Rick, I don't think that anyone thought that you were anti- Minelab just a frustrated beginner. Thats all. I had a battery that did just about the same thing you have described. So I ordered a new one and found that the new battery held the charge and lasted longer in the machine while in the field. What I did to cure the problem was I forgot and left it on top of the car and by the time I remembered that it was there it was sliding down the road beside the car as I looked out the window. Thinking that it would probably be no good I just left it in the car. Well last week by mistake I put that battery into one of my explorers and when I realused what was up I was surprised that it worked just fine until I turned on that light an then the drain started. Now no matter how good I think the batteries are I never go any where without my spare.
 
I am glad someone has had the same problem as me.I am going to my three places to hunt it is 8:36am and we are all walking out the door.I have three kids to entertain too but I will still get some good hunting in.everyone take care and Carry spare battery packs.
 
I have seen the same thing, in certain areas I start getting what seems like more interference when the battery pack goes below half way. I have also seen it with a full pack that drops and raises intermittantly. I dont think its because the battery itself is low, but from bad contact between the battery and the spring contacts.. Make sure you cleant the battery terminals once in a while.. if they start getting that gray black buildup. also you can clean the springs with a pencil eraser.. I like to have as full a charge as I can and when mine gets below half I generally change out the pack.. Dont know if it actually helps performance but it makes me feel better to know I got plenty of juice, and since I have 5 battery packs(3 nimh and 2 alkalyne that I filled with 1800 nimh batterys) I might as well use them once in a while <IMG SRC="/forums/images/smile.gif" BORDER=0 ALT=":)">
 
If some of us can get together for a large order we can really get cheap batteries. Here's the site below check it out.

Mike,
I uses the Sunray charger with the Explorer alkine battery pack to charge 8 batteries at a time. The Q12 comes with a cradle that the pack sit in and will charge them up in around 4 hours. It will work with the stock rechargeable pack too.
I have 3 set of them I carry with me as the wifes MXT uses the 8 AA too and all I have to do is take them out of the Explorer pack and put them into her Whites pack.
I highly recomend the Q12 to anyone using rechargeable AA batterys.
Rick
